Can i put cannabis seeds directly in sunshine advanced

Growing marijuana basing on latitude

Marijuana is a plant that grows outdoors throughout the entire world – except in the Poles – either wild or under the care of a farmer. For a crop to be successful, we must consider when to grow it and the most suitable marijuana strain to use. This post aims to provide information on growing marijuana based on the latitude in which we are.

Climate world map

The latitude on the Earth has a direct impact on photoperiod, in other words, on the daily hours of darkness and sunlight. In turn, latitude also determines the planet’s geographical zones. Taking into account that marijuana is an annual plant – it germinates, flowers and is harvested in the same year – and that its different phases are related to the photoperiod, we come to the logical conclusion that, based on our geographical zone in the planet, the growing period of cannabis varies. Mild temperatures and low humidity during the flowering stage provide the ideal conditions for harvesting top quality marijuana.

To simplify the information, as it’s a very broad subject, three major areas have been identified: northern hemisphere, intertropical zone and southern hemisphere.

Growing marijuana in the Northern Hemisphere

It comprises the half of the world that is north of the equator. The longest day in the year occurs between 20 and 23 June (summer solstice). The shortest day (winter solstice) is between 20 and 23 December. Day and night are the same length (equinox) on 20 March and 22 September. For cannabis farming, we will mainly focus on two areas: the Iberian Peninsula and the Canary Islands.

Marijuana in the Iberian Peninsula

It is situated between the 36º and 44º North. Although its climate is mild due to its latitude, crops must be adjusted to the climate and latitude of the area where they are grown.

Early Maroc from Philosopher Seeds, almost ready to harvest

Luckily, in the Iberian Peninsula almost all marijuana strains grow in perfect conditions. The only problems that a grower may encounter are with equatorial sativa strains that can finish their flowering by the end of November or even December.

The ideal months to start growing marijuana are March, April, May and June. You can also do it in July and August, but only the autoflowering strains are recommended in this case, for they do not depend on photoperiod but need a maximum of sunshine – and daily light hours – for a productive yield. In addition to the last chances of frost during spring, choosing the month we start growing depends basically on the strain and its needs, so if we have enough space, planting during the waning moon in March can produce large plants of the size of Moby Dick from Dinafem, Domina Haze from Kannabia or Jack Herer from Sensi Seeds.

If you are growing marijuana on a terrace or in pots, April and May are ideal months to start growing early strains. Early Maroc from Philosopher Seeds is an option to bear in mind, as it can be harvested in the first half of August. Plant it in June if you want to control the height or reduce the growing time of sativa strains. Notice that the cycle of cannabis plants ends in Autumn, so you should choose the fastest plants according to the Iberian Peninsula latitude, as they can be harvested before the cold and heavy rain period start.

Types of weed for the Canary Islands

The Canaries are located between 27º37′ and 29º25′ North. The climate is mainly subtropical, but it varies depending on altitude and slope, north and south. Except in areas with cooler microclimates, on these “lucky” islands you can grow at least two outdoor crops per year naturally. The planting months are from March to June and from September to November, to be harvested in March, always depending on the strain and its quality.

Growing marijuana in the intertropical zone

Tropics are the region between the Tropic of Cancer and the Tropic of Capricorn. In the intertropical zone there is little variation on the photoperiod throughout the year, while in the equator (latitude 5° N / 5° S) there is a constant photoperiod of 12 hours of daylight and 12 hours of darkness.

Neville’s Haze from Mr Nice

As we approach the Tropics there is a maximum variation of one hour during the day, which varies in the calendar depending on whether you are located north or south. For example, in the Tropic of Cancer, the months with more daylight hours (13) fall between May and August, while in the Tropic of Capricorn, it will be between November and February. As for the weather, usually these are warm areas with no frost risk. However, like in the rest of the planet, this may vary depending on altitude.

Given the photoperiod in these latitudes, marijuana can be grown all year round and the plants behaviour will be almost like that of autoflowering strains, i.e. they will go into flowering when they reach maturity, regardless of the current photoperiod.

A hindrance when growing weed is rain, specially during flowering. It is recommended to be prepared for drought and rainfall periods so that we choose the right month to harvest. Direct rain water to plants should be avoided during the flowering period, so using a cover can solve the problem of rain. However, suffice it to say that cloudy skies have an impact on harvests and final yields.

In the intertropical zone, Indica strains don’t grow as vigorous as in areas further from the equator. However, the tropics characteristics are ideal for Sativa strains, local or commercial strains containing tropical genetics such as Acapulco Gold from Barney’s Farm, Oldtimers Haze from Ace Seeds and Neville’s Haze from Mr Nice, for they will easily adapt to these conditions.

A good way to overcome nature constraints when harvesting marijuana is using a grow lamp in order to grow the plants indoors or in a greenhouse, and taking them outdoors when we wish to make them flower.

Growing marijuana in the southern hemisphere

The southern hemisphere is the area located south of the equator. The day with more daylight hours in the year is 21 December, which is when daylight hours begin to decrease. The shortest day falls on 21 June, coinciding with the winter solstice. On 21 March and 21September, day and night are of equal length. These are called fall and spring equinoxes.

What are the best marijuana strains to grow in Argentina, Uruguay, Chile, Paraguay, southern Brazil, South Africa. 23° to 33° south

In the area comprising 23 and 33 degrees south, the months with more daylight hours are November, December, January and February. Depending on the area, we find subtropical or semitropical climate in all its variations. In most of the area the climate is mild, but because of its montainous landscape there may be serious chances of frost and even snowfall.

White Afghan (23 to 33 degrees south). Depending on altitude, at this latitude, at least two outdoor crops can be produced without artificial lighst.

In warmer areas it is possible to grow two outdoor crops per year. In the winter, the yield will be poorer, which is ideal for experimenting with local seeds. In the summer, selected cannabis seeds are recommended, so you can grow strains such as Nexus from Eva Seeds, Channel + from Medical Seeds and Easy Haze / K13-Haze from Philosopher Seeds . You can get excellent yields in terms of quality and quantity ensuring a great stash of marijuana for the rest of the year.

What are the best seeds for Argentina, Chile, South Africa. 33º to 50º south?

In these latitudes, the four seasons are perfectly differentiated, so there are chances of frost in almost all areas, being abundant in high areas and of course, in areas nearer the South pole.

The ideal time to start growing marijuana depends on altitude and risk of frost – either at planting or harvesting – of the area where it is going to grow. It is also recommended to take into account what strain is planted in a certain month -this will avoid unexpected results regarding the final size of the plant.

Mataró Blue from Kannabia Seeds, late October

For those experienced growers seeking large plants, September and October are ideal months to start growing. For beginners, a good option is to start growing autoflowering strains, for they are fast and thus avoid salt accumulation or potential pests that may occur in regular seeds during the 5-9 months of their cycle. It is recommended to pay attention to the weather, as frost is still a risk. By covering your plants or moving them indoors at night you can avoid wasting time and money.

If you start growing in November or December, you will avoid problems related to low temperatures. Marijuana plants are nicely developed with 14-15 hours of sun in this season and if the growing conditions are good you will get large plants, whether you are growing them potted or in-ground. These months are also ideal for growing autoflowering strains, such as Maxi Gom from Grassomatic, Deimos from Buddha Seeds and Jack 47 Auto from Sweets Seeds, as they are productive cannabis strains despite being automatic. If Rudelaris genetics are not available, any regular strain will develop well.

Mataró Blue from Kannabia Seeds, late December

January is perfect if you want to grow sativa cannabis strains that do not exceed 250 cm in height. You can also grow indica strains, but they won’t get big, although they will be perfectly developed, especially if planted in the early days of this month. Growing autoflowering seeds is recommended – as well as during the mentioned months – even at the end of February, when you can also start growing tropical genetic seeds. In this case,keep in mind the weather conditions when harvesting it.

Mataró Blue from Kannabia Seeds, about to be harvested

As in the mild area of the northern hemisphere, plants will end their cycle in Autumn. Based on the strain, climate and when you started growing it, the harvest can be between late March and May. Some pure sativa stains can be harvested in June.

Hello! Thanks in advance for your help. I live in North America, at 32° N Latitude. I would like to breed a semitropical African strain from 19° S Latitude with a strain from Kwazulu Natal Province, SA, 29° S. Latitude, which did VERY well here last season. I’m thinking the subtropical strain – from Mozambique – might increase the potency of the F1 generation. My question is: will this work, trying to hybridize strains from latitudes this far apart, roughly 800 miles? Can hybridizing these two strains produce offspring that will flower in the fall here (when the SA strain flowered), or much later? Thanks for your time!

Tim Alchimia 2022-01-10
Hi James, thanks for your comment and question. Wow, you have some really exciting and exotic genetics to work with, they sound really interesting and you should get some fantastic results. There will definitely be an increase in vigour with the F1 generation and, if the subtropical variety is itself a more potent plant, then it ought to increase the potency relative to the original Kwazulu variety. I don’t see any issue in hybridizing two varieties from distant locations, in fact, the less they are related, the more vigorous and interesting the results ought to be. As far as the flowering times go, it’s inevitable that the subtropical genetics will increase the overall flowering time, however, you should find examples within the F1 population that would flower in a similar timeframe to the Kwazulu, as well as very long-flowering plants much more alike to the semitropical variety. So, I would recommend pheno-hunting from a large population to find suitable plants which can then be used for further breeding to fix the characteristics you’re looking for, whether they be faster flowering, increased potency, resistance, etc. I hope that helps, best wishes and happy growing!

Hi, thank you so much for a very informative article on growing cannabis based on latitude, as well as the blog to pose questions. Just by reading throught the blog I have learnt a lot. It is interesting to note that a large percentage of the questions being posed on the blog concern growing in the intertropics. It’s unfortunate that most of the information on growing cannabis caters for people living in the northern hemisphere. Hence this website and blog comes as a breathe of freshair!! I would appreciate help on the following: Currently living and growing in Cape Town, South Africa. So doing things at generally oppersite times to the northern hemisphere. Have been asked to setup a grow in a country to the north, latitude 9 degrees south of the equator. Region is classified as subtropical. Elevation is 1000 to 1800m. Rainy season October to April. Drier months May to August, humidity in this period 50% to 59%, temperature during these months 9 to 29 degrees. Longest day of the year is 21 December at 12hr 41 min, gradually dropping to 11hrs 33mins on 21 June (shortest day of the year). I would like your opinion on the best time to start a grow for the best possible results in this region? My thinking is to veg in the wet season and flower in the dry. But my concern is that from late June the flowering plants might start to reveg as the daylight hours start increasing. Could you please advise. Thank you.

Tim Alchimia 2021-10-27
Hi Nibor, thanks for your comment and kind words, we’re so happy that the info on our blog has been useful to you! You’re right though, there’s not a lot of information related to cultivation in the intertropical region on there, but I guess this is because the vast majority of our client base is based here in Europe. That said, I’m sure it’s every outdoor grower’s dream to be able to flower cannabis almost all year round, and in the tropics that’s possible, and indeed it can be quite hard to avoid, so there’s really not much chance of your flowering plants revegetating at all, I don’t think that the daylight hours are enough to trigger regrowth, even on the longest day of the year. You’re correct to suggest that vegging during the rainy season is the best approach, the high humidity will really help the plants grow vigorously and get to a good size. Adjust the sowing time depending on how large you want to grow your plants, calculating that you’ll want them to start flowering at the end of the wet season. You can use supplementary lighting to ensure that the plants keep growing until you decide to let them flower, and then when that time comes, simply stop providing the supplementary lights and the flowering will be triggered by the natural photoperiod. If you are cultivating pure landrace varieties from the same area you’re growing in, then you probably won’t even need to use any extra lighting as these genetics will be fully acclimatised to local conditions and photoperiod, and will grow following the natural rhythms of the seasons, which most likely still follow the same pattern of veg growth in the rainy season and flowering during the dry season. I hope that helps. Best wishes and happy growing!

Chad 2021-08-25
My plant has been outside since a wh b4 june and the plant is green and still growing when will it start to either get buds on it

Tim Alchimia 2021-08-27
Hi Chad, thanks for your question. The answer will depend on a couple of factors, the first of which is the genetics of your particular plant. Fast-flowering Indicas will start to flower a lot earlier than equatorial Sativas, for example. The second main factor in outdoor flowering is the potential for light contamination. If your plant is in complete darkness all through the night then flowering will proceed as normal. If, however, the darkness is interrupted by, for example, outside lights on a house, street lamps, car headlights shining on it, it could easily delay the onset of flowering indefinitely. It’s vital that the dark period is unbroken. That said, and assuming your plant is an Indica/Sativa hybrid and that there’s no problem with light contamination, it would usually begin flowering around mid-late August. I hope that helps, best wishes and happy growing!

Looking for some direction on the best seed types for my area. I am going hydroponic this time and have my set up. Living in Baja I always seem to get bad leaf burn right before hurricane season …UV index 10. Looking for something that can handle the high heat and UV. Thanks and love reading your answers to others questions, has helped a lot.

Tim Alchimia 2021-07-02
Hi, thanks for your comment and question. I always try to recommend that outdoor growers choose genetics that originate in their geographic area, where possible, or at least from a similar latitude to yours (either above or below the equator). In your case there are some Mexican landrace options to choose from that’ll probably do really well in your area, but I’d also recommend taking a look at what outdoor growers in places like San Diego & LA are growing as the conditions aren’t too different. If that kind of Sativa isn’t your thing, you could look at Lebanese or Moroccan genetics which are well adapted to high heat and blazing sun. You could also look at pure Afghani genetics, which are also suitable for this kind of conditions. Personally, I’d probably hedge my bets and try all these suggestions to see which perform the best. I hope that helps, please let us know how you get on! Best wishes and happy growing!

Bread Cruz 2021-05-09
I have heard that a hotter clime may be mitigated with a combo of appropriate genetics and CO², any recommendations for landrace strains that might be appropriate for acclimatization to 32° 46′ N 96° 48′ W. We have many days over 100°F. Am I way off base in thinking something like Durban Poison would do well after a few generations?

Tim Alchimia 2021-05-12
Hi, thanks for your comment. In your situation, I’d most definitely be looking towards Mexican landrace genetics as well as other Central American landrace varieties such as Panama, Colombia, Honduras, Guatemala, etc. although the Mexican strains will be more adapted for your climate conditions. Things like Acapulco Gold and Oaxaca would be ideal, and the various hybrids using them, such as Destroyer, Mexican Sativa, both of which would be good options. As far as Durban Poison goes, not a bad idea to find the examples that can deal with your climate and then breed with them to produce an acclimatized seed line, that could definitely work! Best wishes and happy growing!

shimmerveil 2021-02-27
Hi there, newbie grower thought I would give bag seeds a crack outside at Lat -45 or -46ish. Local seed. Didn’t get them them sprouted until early December, are healthy and in the preflower stage now (late feb). Just a bit concerned I am gonna run out of good weather for the flowering stage because our daylight hours are pretty long down here, just wondering if you have any advice to help me on my quest? cheers

Tim Alchimia 2021-03-02
Hi, thaks for your comment and question. If I’ve understood correctly, you’re in the southern hemisphere, around the same distance south of the equator as we are north of it, so the seasons are reversed. meaning you’re towards the end of summer. If they’re in the pre-fower stage now then they’re on track for harvest at the end of April/start of May, depending on the genetics – Sativas will take longer, Indicas will finish earlier. You say you panted local seeds, so the chances are that they will be acclimatised to the conditions in your area. If you think that the weather there will be too bad for the plants at that time of year, you could try covering or protecting them from the worst of the elements with a clear plastic sheet/rudimentary greenhouse, for example. Alternatively, you could bring the plants indoors or to a dark shed or garage overnight, as long as the plants won’t be exposed to any light pollution which could interrupt the flowering. I hope that helps, best wishes and happy growing!

tony 2020-09-06
hi! i was wondering what strain would be best suitable for outdoor growing. i currently live in mexico Latitude N26´54. climate here is mostly dry with 30 plus celcius degree average temp. on hottest summers it goes up to 42 celsius degrees. would it be better to grow an autoflower? a photo?

Tim Alchimia 2020-09-08
Hi Tony, thanks for your comment and question. You live in a great place to grow cannabis so I wouldn’t waste my time and efforts on growing autoflowers, they’re best in cold, wet climates where the summers are short and it’s vital to harvest before the autumn rains and frosts arrive. In your position, I’d be looking at some kind of Sativa hybrid, and if possible something with some Mexican genetics in the hybrid so that there’s a certain genetic adaptation to the climate there. Fast-flowering hybrids like Destroyer would be ideal, as would almost anything with some Haze influence. Also, Sativa varieties from other countries on your latitude ought to do well too, such as Morocco and much pf North Africa, India, Burma, etc. I hope that helps, best wishes and happy growing!

Billy T 2020-07-23
Last year I grew enough bud to last the whole year. This year had an issue with rooting critters, so I’m down to one healthy plant. I want to try a fall crop. I’m at 33°lat, 86° long. Have Collin OG AND OG SOUR seeds. My concern is that there may be too much heat when I germinate and in the early seedling stage, as these will be outdoor in pots. When would you recommend I germinate? First frost is typically not before 11-15.

Tim Alchimia 2020-07-24
Hi Billy, thanks for the comment. I’m sorry to hear you had trouble with critters this year, that’s too bad. At least they left you with one good plant, that’s something! The seeds will most likely germinate well now, but you’ll need to keep them in a shady spot until they’ve got a pair of leaves and make sure they stay hydrated (but not water-logged) and they ought to develop well. You’ll also need to give them some supplementary lighting after mid-august until they’re big enough to flower and give you a good yield. Otherwise, they’ll start to bloom when they’re far too small and the harvest will be a disappointment. I hope that helps, don’t hesitate to ask any more questions if we can help. Best wishes and happy growing!

Babb 2020-05-18
How many generations would a certain strain (say cm1) need to be grown and breed to acclimate to new growing climate and be a regional variety of the strain cm1? example seeds from cm1 grown in Cali. I take and plant in Southern Illinois. The seeds from these plants I again plant in Southern Illinois. How many generations until I have cm1 Southern Illinois acclimated stabilized variety? It would be different then the original cm1 we got seeds from grown in Cali. but would still be cm1 strain because no crossbreeding just changed growing environment. That should make it a “regional” variation of cm1 or a new strain all together? Southern Illinois cm2. Thanks in advance for any answers.

Tim Alchimia 2020-05-20
Hi Babb, thanks for your comment and interesting question. Firstly I’m afraid that I’m not familiar with the strain CM1 so it’s hard to assess how much potential genetic variability it has, which would definitely have some impact on the breeding program. Generally speaking, the time it will take to acclimatise a variety to a new environment will depend on a few factors, as I mentioned above there’s the genetic variability of the strain used, but a lot will depend on the selections made by the breeder, and more importantly, the omissions, i.e. the plants he rejects. With the proper selection and breeding practices, the process will be a lot quicker. As for the number of generations it might take, it will depend on the factors I’ve mentioned, but a lot of people seem to think that by taking a variety to F5 (i.e. inbreeding for 5 generations) you can have something unique and uniform. Whether or not it then can be classified as a different strain is another matter. If it shows markedly distinct characteristics from the original CM1 plants then it’s possible. Otherwise, it’s really just the same thing but bred to suit a different climate. Calling it Southern Illinois CM1 would be fine, in my opinion, you’d be clear about the heritage but also recognising all your own breeding work. I hope that helps to clear things up. Best wishes and happy breeding!

JoseMa Is an Alchimia client 2020-04-07
Great thread- Trying to get some info for an outdoor grow in Ecuador. Land race seeds, literally on the Equator but at 10000 feet, so mild Mediterranean climate that is consistent all year long. My question is two fold. How long can we expect the entire growth cycle to be with out light intervention and at what stage would it be best to clone the best looking female plant. Many thanks.

Tim Alchimia 2020-04-08
Hi Josema, thanks for your comment and questions. That sounds like you’ve got a great opportunity for some amazing plants over there, I’m mildly jealous! So the answer to your first question depends on the genetics being grown. Many tropical Sativa plants will flower for 14, 16, 18, 20 weeks or more! From what I understand on the matter, the finishing time is also determined by the time of germination, as the plants are exposed to 12/12 photoperiod they will be triggered to flower when they are mature enough, which apparently can be anything from 2 to 5 months after germination! I’ve read that when they are planted in the ground it can take longer for them to be triggered to bloom and that the roots being restricted in pots can help speed up the onset of flowering. But as I said before, it’s mainly the genetics that will be the deciding factor. If you can find local landrace seeds, and if there’s any way you can speak with local growers to find out how they manage their gardens, then their experience will be able to help you far more than I can. To answer your second question, I’d say that taking clones any time before it really starts flowering will be acceptable. You can take clones as soon as the plants have shown sex and they’ll root very well and quickly, but by waiting a bit longer you might be able to get a better idea of which is the best plant to choose. I hope that helps, all the best and happy growing!

Sam 2020-03-16
Hey, great website, truly. I am planning a grow in tropical South East asia, will be naturally a 12 12 light cycle (planning on growing outside under an open greenhouse (sides rolled up) ) I will grow sativa dominant or 100% sativa (if i can get my hands on some) I plan to grow in a no till planting bed, my biggest piece of the puzzle is, do I plant the germinated seed straight into the soil outside and let it go 12 12, or do i grow the seedlings under a CFL and transplant to outside? if so how and when to do this? thanks in advance, love your resource here.

Tim Alchimia 2020-03-19
Hi Sam, many thanks for your comment and your kind words, we’re really happy you’re finding our blog useful. Wow, what a great opportunity, I’d love to be able to grow some amazing Sativas in their natural environment! I suppose that the answer to your question about when to sow seeds will depend on just how big you would like your plants to get and how much you want to be harvesting when they finally mature, which I’m guessing could be as late as December or January. The earlier in the season you sow, the bigger they will become, which is fine if you’re growing without any concerns regarding the law or nosey neighbours, or simply space restrictions in your greenhouse! Of course, most of these issues can be dealt with by using pruning and/or training techniques, but you can save yourself a lot of trouble by planning ahead. Sativas and Sat-dominant hybrids are usually very vigorous and tend to stretch a great deal at the onset of flowering, so you really need to take this into account so you don’t “overgrow” your greenhouse! As to whether to germinate directly in the soil or start them indoors, well that will mostly depend on how many seeds you’ve got to play with. If you’ve only got a precious few, then I’d germinate them indoors and start them under a CFL, gradually getting them used to the sunlight and planting them out after a few weeks of healthy growth, when they’ll be a bit more hardy and resistant outdoors. On the other hand, if you’ve got plenty of seeds then I’d recommend starting them directly in the no-till beds. You may well lose a few seeds or seedlings to pests, but the strongest will survive and what’s more, I’ve always found that starting plants in the same place they are to mature gives me much healthier and vigorous specimens, compared to other plants that I’ve started elsewhere and transplanted into their final spot. I hope that’s some help to you, feel free to contact us with any further doubts you may have. Best wishes and happy growing!

I’m at latitude 44.07 N and 89.28 W How many weeks of flowering do I have? And when does it typically start ? also we tend to receive storms right during flowering time. Greenhouse isn’t a option with nosy people . I usually shake the excess water off.Sometimes it gets hot after the storms in August and early September. What strains are the best for moist and humid. I Know that the flower time depends somewhat on where the breeder created the strain. I like Sativa knowing when they my flowering in general starts will allow me to count back enough weeks on when to force the Sativa to finish in time. Frost is normally oct 15 it can go on either side of that a few days. -the safest time to set out is April 30 . –

Tim Alchimia 2019-11-28
Hi Corrie, thanks for your question. A lot of the answers you’re looking for will depend on local climate and the prevailing conditions but you’re at a very similar latitude to myself, so the photoperiod will be very similar. Here, my plants tend to begin the transition into flower around 15th August. Of course, there are some exceptions like fast-flowering cultivars that will begin flowering earlier, and some sativas with tropical heritage that take a lot longer to initiate bloom, but as a general rule for most plants it’s the middle of august. As for the flowering time, it totally depends on each plant. It’s not so dependant on where the strain was created though, it’s got much more to do with the characteristics of the genetics used in each hybrid and where they were originally from. Plants originally from mountainous regions like Afghanistan and Pakistan have developed to flower quickly in the short season when conditions are favourable before the frost arrives, and have morphological characteristics to deal with harsh conditions of drought, wind and extreme heat and cold. On the other hand, varieties that have developed in equatorial or tropical countries where frost is never seen will flower much longer, growing much bigger and their morphological characteristics will have evolved to deal with the different climatic challenges of high humidity, heavy rains and monsoon season. It sounds like you’d definitely be best choosing sativa-leaning varieties, the looser flower structure copes with humidity and mould issues much better than the dense buds of indica-dominant plants. We have a wide range of mould-resistant varieties to chose from, and our blog article on growing cannabis in harsh conditions can offer some ideas of resistant varieties too. From my own personal experience, I can recommend Bangi Haze, Nepal Jam, Orient Express and Congo from ACE Seeds, which are all high-quality sativa-dominant hybrids that finish flowering quickly and should be ready before the frosts hit your area. I hope that helps, all the best for next season and happy growing!

StickyFingers 2019-10-05
Hi guys. Writing from 12.4634° S, 130.8456° E at sea level here looking for some advice on good easy grow strains for beginners. Auto flower & outdoor would be good but can come inside if need be. We have monsoon/wet season through summer so mould resistance would be a benefit too.

Tim Alchimia 2019-10-07
Hey StickyFingers, thanks for your comment and question. Wow, you’re certainly at a great latitude for growing tropical Sativas, which are genetically adapted to grow in your part of the world and deal with monsoon/wet season easily. Tropical Sativas can be a challenge to grow for gardeners further away from the equator, but shouldn’t be a problem where you are. All you’ll need is good soil and patience, as some can take a long time to finish flowering although yields will be huge to compensate for the wait. Personally, I would be looking at Sativas from seed banks specializing in landrace varieties from countries on a similar latitude as you, like ACE Seeds (their Bangi Haze is a fast-flowering and highly resistant Sativa and their Panama is astounding), Cannabiogen, (Destroyer in particular is an easy-to-grow and highly satisfying plant) Seeds Of Africa or Underground Seed Collective. Look for landraces from Central America, Central Africa and South-East Asia, for example Colombian, Congo, Thai, and bear in mind that any hybrids containing afghani, kush, skunk etc. will be more likely to suffer from mould during the wet season while the pure Sativa strains will withstand this due to their later flowering and their more open, airy flower structure. Auto-flowering plants will be fine if you can avoid the wet season, but as a general rule, they don’t deal with rain very well. I hope that’s helped, all the best for the season ahead, please let us know how you get on. Happy growing!

Brave 2019-07-23
Thanks Tim. I’m working on it. I’m going to post my solution to anyone growing outdoors in the tropics. Like Tim suggested just 15 mins of light in the night will disturb the dark process or flowering process. Hence enabling the plant to continue in a vegetative stage until it reaches a size/height suitable to the grower. Then simply don’t use the light and let our natural 12/12 take over to flowering. For those like me, who need an auto system. Here’s what you need. I spent all day on July 21, 2019 mentally trying to set up a solution. Keep in mind everything can be found on Amazon. I don’t post links due to the fact, I don’t want others to think I’m benefitting off affiliate 1. 10W Solar Panel 12V. 2. A charge controller 3. A 12v rechargable lead acid battery 4. A Digital Timer to automate the process, which will avoid me going in the bush every night. 5.100w Waterproof outdoor grow light or lights so basically the reason these are necessary is due to the fact that, you want to automate the process of giving the plants extra light, but not all night. If you have a light on all night in the bush. It’s likely to draw attention from folks who go in the bushes at night. Tim recommended lighting for 15 mins, which is great, but I suppose you can do so for 30mins to 1 to 2 hours. THe solar panel is hooked to the charge controller (prevents the panel from over charging the battery, you will need it since u won’t be present to unplug the panel from the battery if you don’t have a controller). The battery is then connected to the charge controller. The real automation is the digital timer. It is also connected to the charge controller. So charge controller take power from the panel, to the battery. The battery send power to another channel in the charge controller, which is then released to another connection to whatever product u want to power up. The grow light will then be connected to the timer, and also the charge controller. There will be some wiring involved, but youtube has vids on setting up digital timer. Its something that’s common, many use it to automate their chicken houses among other things. Here’s a Youtube link explaining how to set up with Panel to charge controller to battery (no digital timer) but you can add with imagination. In this vid, where you see the fan connected would be where the Timer would be connected on that charge controller. Hooking up the Digital Timer has some mid-level home electric skills to it, hence many who purchase don’t know how to hook it up. Here below is a vid of an indian guy explaining how it’s done. So add the two links together or show them to a friend who does electricity and you’ll get set up. The wiring set up starts at 8:40, prior to that he showed how to set the time on the timer for automation which would be our end goal after setting up everything. N.B this vid does not have a Charge Controller. But any friend who does basic electricity home connections for a living can get around this. This is the best vid on wiring the digital timer I’ve seen on youtube. If Tim says it’s ok to post links to the amazon products, then I gladly will. But this is what I came up with, it’s the best solution for us who don’t sleep in the bush, who got ordinary work life and plant as secondary income. This set up would ensure that we grow indica/sativa photos as large as they grow in the colder climates. The automated light would break the flowering triggered by early darkness in our 12/12 year round climate. Tim said just 15 mins of light on the plants is good enough. I’m thinking of 30mins for extra coverage.

Brave 2019-07-21
Re-reading your first comment to mine. I now realised you addressed this, and only now seeing that. So just 15 minutes of light is needed to interrupt the plant from flowering. The reason why I wanted a light that comes on automatic n goes off on my timing. Is because I’m doing guerilla growing, it’s not close to home. it’s like 15 mins walk up a hill, offroad and in the bushes. So I wouldn’t have to go every night to the grow spot.

Brave 2019-07-21
Tim I appreciate your response as it helped me understand my location more when it comes to cannabis. I have a suggestion as I’m trying to work around this. How about if I got solar spotlights, to interrupt the dark period for about 2 hours? They come on automatically as darkness hits, and prevents the plants from going into flowering mode. I have one little issue with the spot lights. I can’t find one with a timer. It’s not needed to be on all night, as this also could make my grow area be found at night by wanderers. Hence why I’d like a timer that shuts it off after even 1 hour to 2 hours. If the solar spotlights have no timer to shut off, do you think a solar path light would work effectively? They would be on all night, but as we know they’re much dimmer than a spot light, not sure if a path light gives off enough light to interrupt flowering when dark falls. This is how I’ve thought of preventing the flowering stage in my zone, and enable the plants to grow bigger and longer period. If you have a solar powered light you could recommend, I’d gladly check it out.

Tim Alchimia 2019-07-22
Hi Brave, thanks for your comment. Personally, I wasn’t sure if those path lights would be bright enough for the purpose, so instead of a spotlight I decided to go for some solar-powered LED strips from a local hardware store, which seem to be the perfect compromise – not too bright so as to attract unwanted attention, but bright enough to properly illuminate the plants. Additionally, the flexibility of the strips means it’s really easy to adapt them to any situation, fitting them in a way that lights the plants but without letting too much light spill out to the surrounding area. Although, as you say, a solar lamp with a timer would be the best option, I’m still looking for one, no luck so far I’m afraid! All the best of luck for the season and happy growing!

Susi sorensen 2019-07-19
I started outdoor clones in San Diego June 12, then I moved them to north of San Francisco July 5. They look like they are trying to flower and vegetative growth is minor, not much branching. Was this an effect of moving them to a more northern latitude. They are mostly kush varieties

Tim Alchimia 2019-07-22
Hi Susi, thanks for your comment and question. Moving them further north at this time of year shouldn’t provoke them to start flowering because, in theory, the days are slightly longer the further north you go, until the autumn equinox anyway. Is there any chance that the plants were in darkness for more than 12 hours at any point during the move northwards? If so, then that could be the cause of the problem, otherwise, I can’t really think of any reason they’d begin to flower, apar from it sometimes happening if the plants are rootbound and are long overdue a transplant. Some particularly sensitive varieties can begin flowering as a reaction to stress, in this case, possibly the stress of the move could have caused it. Of course, it’s also possible that the plants are very early-flowering varieties, and that beginning the bloom phase this early is perfectly normal for the genetics you’ve chosen. There are plenty of variables, it’s difficult to know what could be the root cause, but either way, I hope the problem resolves itself and that you end up harvesting a nice crop of buds. All the best and happy growing!

How long would a sativa veg in the tropics?

Brave 2019-06-06
Also I’d like some understanding for my zone. In the tropics, the long grow period from April/May to Sept/Oct, we call it long crop where I live. The ideal strains are Sativa photoperiods. Can description that says “Mostly Sativa” work also? Suppose I decide to buy some sativa photoperiod strains. Then I plant them in September/October, will they flower as autos do, due to shorter light days leading up to Dec/Jan? Or will they stay in veg stage till next September harvest? Early Maroc strain, is it only for July to August harvest? Can it be used in my Tropics zone any time of the year? Also from my understanding, In the Tropics, Indica photoperiods cannot be grown outdoors for a long vegetative growth. I first have to either grow indoors or in a tent with long light cycle until desired growth is reached. Then I can take it outdoors to begin flowering. Basically indica for outdoors was meant for areas 25 degrees and beyond, north or south of the equator. Just clarifying if I understood correctly.

Tim Alchimia 2019-06-06
Hello Brave, many thanks for your comments and questions, I’ll try and help you the best I can. As you’ve already found out (and yes, you’ve understood it correctly), the critical night length to trigger flowering can vary depending on the genetics chosen. The Indica varieties are from areas of the world with long days and short nights in summer, and vice-versa in winter, so at your latitude, they began to flower almost as soon as they sprout. Now your plants are flowering they will continue until mature, so yes, you can effectively harvest them like autos. If you’re growing purely outdoors without any electricity then Sativa genetics are probably your only option. While seed banks may classify a variety as being Sativa-dominant, that doesn’t mean it will match everyone’s idea of what a Sativa is, or perform well in tropical zones. One frequently sees OG/Cookies/Diesel etc. labelled as mostly Sativa, which I think can be a little misleading. Another thing to remember if you’re growing a Sativa-dom hybrid from seed is that you’ll find some plants are more Indica-leaning, with others more towards the Sativa side. For your latitude I’d recommend seed banks like ACE Seeds,, USC and Seeds Of Africa for good quality pure Sativa and mostly-Sativa hybrids based on landrace genetics from tropical zones. I’m not sure about sowing them in September though, I guess a lot would have to do with local seasons, I don’t know if there’s a rainy season or not. Personally, I would sow as soon as humanly possible so that the plants can grow to a reasonable size over the summer and give a decent harvest in December/January. Regarding the Early Maroc, in your climate and with the natural outdoor photoperiod, you could be flowering pants like that all year round if weather permits. If you’ve got lots of seeds, you can do a Sea Of Green (SOG) type grow with lots of small plants giving you one main bud each. If, however, you want the plants to grow bigger before they flower, you could give them some additional illumination to extend the day or break up the night time. This would keep them in vegetative growth until you felt they were a good size to begin flowering, at which point you’d simply remove the supplementary lighting. If you don’t have mains electricity another option would be to use a solar panel to power low-energy LED lights. Switching the lights on for 15-30 minutes in the middle of the night can be enough to keep the plants from flowering. I hope that’s answered everything, all the best for the rest of the season and happy growing!

Brave 2019-06-05
Tim I came across this page looking for solution. I planted photos strain of Afghan Kush and also White Widow. My countries latitude is 15° north. Clearly in the tropics. They have begun to flower to my dismay. I was hoping for a long veg grow b4 flowering. Will the flowering phase last up till Sept or will I have to harvest like the autos. To be clear, it means I need to plant on sativa photos for my region? here I was hoping to shoot for a 1lb a plant with a long veg. So disappointed.

SunFan 2019-05-31
Tim I’m trying to figure out what I might expect with the length of vegetative and flowering cycle times. I’m in central Mexico, 22 degrees lat, 5,000 feet up in the Sierra Madras mountains. Climate is classified as high dessert. Daylight varies very little, averaging 12 hours a day with maybe a swing of one to two hours summer to winter. Temperatures are very moderate, averaging 70 degrees. Lots of sunshine. I planted some seeds from a friend two months ago. Variety unknown. They’re up about 18 to 24 inches now. Its now the beginning of June. What might I expect for the end of vegetative growth and the start and end of flowering? Is there an optimum time of the year I should be starting seeds? TIA SunFan from Lake Chapala, Mexico

Tim Alchimia 2019-06-05
Hi SunFan, thanks for the question. A lot depends on the genetics you’re growing, for example, an Indica variety would most likely flower straight away outdoors with that kind of photoperiod, whereas a pure Sativa that’s adapted to your latitude would grow for the whole summer and begin to flower as autumn approaches. By the sounds of it, the seed your friend gave you must be Sativas, because if not, and they’re Indicas, I think they’d have begun to flower before now at your latitude/photoperiod. In this case, you can probably expect them to get quite big over the summer, this is the peak period for plant growth. I’d imagine that towards the middle/end of August, the plants will begin to flower and hopefully be finished at some point before Christmas! Without knowing the genetics, it’s really difficult to predict when a plant will be ready for harvest, but as long as you protect them from frost and the weather doesn’t turn really cold and wet they will be fine, and you’ll need to pay close attention to the colour of the trichomes as they mature. This is all explained in another of our blog posts “When to harvest according to trichome ripeness”. As for an optimum time of year to start seeds for the outdoors, it mostly depends on a combination of factors, such as the genetics, the size of plants we want, and most importantly the climate in which we grow. If a grower in a warm climate wants large plants, he will germinate seeds in January and grow them up over spring with supplementary lighting to ensure huge plants by the end of summer, whereas someone in a northern country who doesn’t want their plants to get too large can start seeds in mid June and still get a decent harvest without the plants growing too large. I hope that’s helped to clarify things, all the best for the season ahead, good luck and happy growing!

Tan 2019-04-12
Hey there, this is a very nice article and it is very helpful thank you!! I live in the tropics located 22.3° N, 73.18° E This year I am planning to grow during September but I am confused whether the plants will flower or will it continue its vegetative growth once it matures. Maximum sunlight received from September to February will be less than 12 hours, somewhere around 10 hours. But after the winter solstice that is 22 December will my plants still flower or continue vegging? So, my question is should I grow feminized seeds during this period or should I grow autoflower?

Tim Alchimia 2019-04-15
Hi Tan, thanks for the question. If the daylight hours are less than 12 or 13, then the plants will continue to flower, no question. As long as the conditions are warm enough then you’ll be able to grow some amazing long-flowering Sativas. Autoflowering plants are not designed for your latitude, they’re for much further north where plants need to flower during the long days of summer to avoid the early autumn cold and rain. Where you live, plants can flower pretty much all year round, and you’ll be best planting Sativas which will give you the best vegetative growth before flowering. Indicas and Indica-dominant hybrids will stay very small and produce very little as the will begin flowering as soon as they are mature, behaving pretty much like autoflowers do. Sativas, however, can be germinated under 12/12 photoperiod and still easily reach 7ft tall by the time they finish! I hope that’s cleared things up, all the best and happy growing!

James P Yale 2019-03-23
Hello Tim: nice website ya got about some outdoor grow recommendations for southwest Florida.

Tim Alchimia 2019-03-26
Hi James, thanks for the kind words, and for the question too. Really the best thing is to talk to local growers and see what they’re planting and how they do it, but I also realise that in non-legal states this isn’t as easy as it sounds, so I’ll help the best I can. I don’t know too much about growing conditions in your area, but I do know that it’s generally fairly humid there and that mold is a very real risk. We have a post all about, but it’s really aimed at more northerly growers, whereas you’re quite far south so you have more options open to you. so for outdoor growing, you’ll probably be best with something very Sativa-leaning, almost pure. The looser, more airy floral structure will greatly help to keep botrytis/bud-rot to a minimum, and I don’t imagine you suffer from frosts in autumn, so your flowering season will be easily long enough for these varieties. Personally, I’d be looking at varieties based on landrace strains from the general area/latitude, so start with Central American and Caribbean varieties like,,,,, etc. and the various containing them can also offer another interesting option. I hope that’s helped you out, if you need any more advice, don’t hesitate to ask. All the best and happy growing!

harlz 2019-03-12
hi what are the best strains to grow outdoors in new zealand ? cheers

Tim Alchimia 2019-03-19
Hi harlz, thanks for your question. So I can help you, can you tell me roughly which part of NZ you’re growing in? There’s quite a difference in seasonal conditions between the top of the North Island and the bottom of the South Island, which would greatly affect your choice of variety.

Daniel 2018-12-06
well, this make sense of why my plants started to flowering so soon(intertropical country), well, next time I will try in the “dry season”, next time I will try an hybrid indoor/outdoor, get some lights and run them for 3 to 4 hours when it get dark so they can grow a bit then turn them of to flower, also what strains you guys recommend for intertropical countries? also there is a chance you guys ship to Costa Rica? thanks

Joey 2018-07-31
Hello.just want to know if I plant in August in Sydney Australia when could I look at Finishing .I have MBs xwhite widow .c99 . it’s still a little cold start them in greenhouse and plant out .never grown out of season before.and would they stretch alot..thanks your knowledge would be greatly appreciated.

Tim Alchimia 2018-08-02
Hi Joey, thanks for your question. At that time of year there are only 10-ish hours of daylight in the day, so the plants would begin flowering as soon as they’re mature, usually after growing 4-5 sets of leaves. They won’t grow very big with so few hours of light, and they oughtn’t to stretch too much either. If you want to give them a better start I’d recommend starting them indoors and growing them under lights for a few weeks, letting them get to a bigger size before putting them in the greenhouse to flower. All the best with your grow, happy planting!

Mic 2018-04-05
What strains do you recommend for the intertropical zone around the Tropic of Capricorn. Would sativa dominant strains veg longer

Tim Alchimia 2018-04-10
Hi Mic, thanks for your question. Wow, how lucky you are to grow in those latitudes, you’ll be able to grow some amazing tropical sativa genetics there for sure! Firstly I’d look at landrace varieties from countries that have a similar latitude, here at Alchimia we stock two highly reputable seed banks that work with landrace sativas, firstly ACE Seeds who have some excellent pure varieties from Panama, Honduras, Ethiopia, and Malawi as well as some very interesting sativa hybrids like Zamaldelica, Golden Tiger, Old Timers Haze or Tikal. Then we also have Cannabiogen with their Colombian Red or Destroyer (Mexico x Colombia x Thai). Other varieties worth mentioning are Zambia from Tropical Seeds, Double Zamal from USC, Mangu Karot from French Touch. Those are just a few suggestions, but by searching our shop for “landrace” or “sativa” you’ll see a whole range of options. Have fun deciding! All the best and happy growing.

Alexander 2017-09-23
Hi I would like to grow Autos outdoors, im located in 31N 32E Can you recommend best indica/sativa auto strains for this climate Many thanks

Dani Alchimia 2017-09-25
Hi Alexander, With your climate, as long as plants have enough irrigation they’ll be ok. Most of the automatic strains in our web will adapt perfectly to your climate and location. That being said, I’d recommend you Fraggle Skunk Auto if you want high yields, Sweet Nurse Auto if you want CBD and a more medicinal effect, or OG Kush Auto if you want a tru intense effect. Hope it helped!

Isleno 2017-07-26
Thanks for the fast and helpful response! So, if I understand correctly, it should be all year like “flowering” hours, is that it? I would BE able to use photoperiod and clones for quick harvest and not big size. Or vegetate indoors then take outside? This is good news to maybe not depend on autos. Light pollution is a concern however. But this info should push me to try a photoperiod to see how it turns out for a test.

Dani Alchimia 2017-07-27
Hi Isleno, I’d definitely try some photoperiod strain and see how it performs. Most people I know who live in Canaries use their outside yard as a flowering room, they know plants will start flowering as soon as they’re taken outside during – almost – all year, so they grow them indoors and take them outside when they have the right size. Light pollution may be a problem, although I can perfectly read a newspaper at night in my yard next to my flowering plants, they’re less sentitive to it than we normaly think. Hope you’ll be lucky!

Isleno 2017-07-25
Hi, very helpful article, thank you very much! I am at 32° 38″, so close to canaries, what advice would you give me on grow schedule and my best bets? Weather is also rather close to canaries: no frost ever, no negative temps, maybe aniversário average humidity. would love some info for future planning anos possibilities. For the moment I have a small terrace that gets direct sun all day however size is a big concern unfortunately so I’m thinking of very small autos to be safe. 🙁 Less than 1 m high is the maximum at the moment, any specific advice on that for not a Pure indica? Would rather have a sativa dominant but doubt it would be possible? Thanks in advance!

Dani Alchimia 2017-07-26
Hi Isleno, You have a nice weather to grow cannabis, although in your latitude plants don’t grow much and start flowering as soon as they reach sexual maturity (3-4 weeks). If you’re interested on mostly Sativa autos, I’d definitely try Philosopher Seeds Cheesy Auto, Sour Ryder ASB or Dinafem’s Amnesia XXL Auto. Hope it helped!

freddy 2017-06-19
Thanks dani! One more question. My mother plant snap ped due to wind, I taped it up in hopes of re generation. Is that a good idea? Or should I cut my losses and take clones?

Dani Alchimia 2017-06-20
Hi freddy, It’ll probably regenerate, cannabis is a very tough plant, although I’d take a couple of clones if possible, just in case! 😉

juan ochoa 2016-11-25
Hello, I would like suggestions on strains for tropical climate outdoors, exactly at 11 latitude, i am growing a seedling with 60% critical mass 40% white widow and its growing well despite the cloudy days we have had since its germination. i am also concerned about mold because of high humidity almost all year round. thank you

Dani Alchimia 2016-11-25
Hi juan, Since you probably won’t have problems with cold temperatures, and taking into account that you grow in an area with high environmental humidity, I’d try hybrids with Sativa dominance. Sativas are more resistant to fungi than Indicas, which often develop more compact buds and are more sensitive to mold infections. All the best!

Breton 2016-11-11
We just passed recreational and legal grow for up to 12 plants in Massachusetts. Final frost is first week of April, we get almost no rain all summer and a peak temp right around 85 F on Cape Cod. We make it to 12/12 right around mid/late October. 42parallel. I would love some input on ideal strains for this area. Thanks!

Dani Alchimia 2016-11-14
Hi Breton, Congratulations for the results of the ballot!! I’d try early flowering hybrids like Sensi Seeds Early Pearl, Barney’s Farm Critical Kush, Philosopher Seeds Easy Haze or Mr.Nice Seeds Early Skunk. All the best!

Artemis2318 2016-08-16
Hi! What strains can you suggest that suit the climate in Central America, especially for a newbie grower?

Dani Alchimia 2016-08-17
Hi Artemis2318, Doubtless, and because of the natural photoperiod of your area, I’d try Sativas or mainly Sativa hybrids. This type of plants grow much more vigorous and taller than Indicas, and are perfect for your climate conditions. Hope it helped!

David 2016-07-17
How are you any suggestion on outdoor plants for Ireland I have a greenhouse will autos work thank you any help will do

Dani Alchimia 2016-07-18
Hi David, Autos will do in Ireland, especially in a greenhouse, although you should grow them during the warmest months of the year. Photoperiod strains with early flowering could also work, like Early Maroc from Philosopher Seeds or C-99 from Female Seeds. Best of luck!

Scubasteve68 2016-07-10
If i started my plants in late june in e colo just east of mountains how big will my plants get outside will they bloom in sept?

Dani Alchimia 2016-07-11
Hi Scubasteve68, Well, it depends on several factors: -Pot size (if you want big plants plant them directly in the ground) -Daylight hours (the more direct sunlight they have, the more they’ll grow) -Nutrients (the more accurate the feeding, the more they’ll grow) -Genetics (mostly Sativa strains grow much taller and wider than Indicas). Depending on these factors, you plant can reach 1-2 metres in height, approximately. All the best!

Nizar 2016-01-23
Hello, im moving to the canaries soon, wanna still make the closest window on March, what do I need? I wanna grow different strains outdoors and maybe some indoors just to know how and try them I like Sativa strains, i prefer the happy/energetic mood, We r a few friends and we will plant enough ? Best regards, Nizar

Dani Alchimia 2016-01-25
Hi Nizar, Basically, growing in the cannaries is almost like growing autoflowering strains. Unless it is midsummer, when they may grow for some extra weeks, plants are usually ready to harvest after 3-5 months from seedling (depending on strains, Sativas will take longer). Here you have a list of some of the best Sativa hybrids on the market. Since plants start flowering at almost any time of the year, many growers grow them a little bit indoors and put them outdoors when they have the desired size to begin flowering. The canaries are affected by sirocco coming from Africa, so perhaps you need to protect your plants from this hot and dry wind, otherwise they could wilt. Hope it helped!

Motlotlegi 2014-10-14
hi, i browsed through your article searching for information that will guide me through a plantation process whereby im interested in growing a marijuana plant that, its height wont protrude higher than 30cm and will produce kush that has a less tiring effect. my ideal location is tropic of capricorn, southern africa. can you please provide information? including of course how to get a hold of the seeds or how to produce them at my own peril. thanx 🙂

Dani Alchimia 2014-10-15
Hello Motlotlegi, If you are looking for a strain short in size, you should look for pure Indica plants or autoflowering strains. The problem is that most indicas have a narcotic/sedative effect, which is not what you want. Thus, I think you should look for short, mostly sativa autoflowering strains , which won’t grow at all like normal strains and will produce an uplifting/stimulating effect. Unfortunately, we are not shipping our products to Africa, so we can’t help you getting these seeds. We hope to publish a post about the basics of breeding in a few weeks, so you can start thinking about making your own seeds. Thanks for your confidence, Best vibes!

Grow Weed Starting From Seed

“Don’t judge each day by the harvest you reap but by the seeds that you plant.”

Growing your own cannabis plant starting from seed is a remarkable journey. Understanding the biology of the plant is one thing, but comprehending how a little miracle bean can turn into a gigantic tree producing flowers that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.

Start Growing Weed From Seed

Our favorite thing about growing your own weed starting from a seed , rather than a clone, is that you get to see the full life cycle and enjoy a plant that is unique, just like you. An entirely new genetic makeup will enter the world for the first time, and if you’re lucky, something remarkable might be born.

Raising a cannabis seedling , however, requires some patience, gentle hands, and a smidgen of luck. Thankfully pot seeds are remarkably vigorous because they are what’s called endosperm seeds , which means they have almost pre-formed cotyledon leaves before you even add water. Below is a brief guide on the techniques we have found yield the most success when starting seeds and raising your seedling to a healthy plant ready for transplanting. And, don’t forget, a Pot for Pot’s Complete Grow Kits take the guesswork out so you always wind up with a splendid harvest!

1) Germinating Your Cannabis Seed

To accelerate germination, soak your seed in a small container with lukewarm water and place it in a dark and warm place (like a kitchen cabinet) for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process on a physical and chemical level. Doing this helps to loosen the shell as it becomes a little softer making it easier for the embryo to crack it open. When your seed sinks to the bottom, it is ready to be planted, and sometimes the seed will pop out a small taproot. A seed can still be planted though if it does not sink or put out a taproot. When a seed pops a taproot (often called a tail), it becomes more vulnerable and it is better to plant it before this root emerges.

2) Planting Your Weed Seed

We see best results with seedling pellets that are made of a mix of compressed peat moss and coco husk. To expand, soak it in water for 10 to 15 minutes. Using warmer, lukewarm water, instead of cold water, will speed up the time the pellet takes to fully expand. Once your seedling pellet has absorbed enough water and has expanded to its maximum size, gently squeeze to remove excess water. The growing medium should be like a damp sponge that would not leave streaks on the table. Dig a small hole about 1/4 inch deep for your seed. Use a spoon to lift the seed out of its bath. If it has popped out a taproot be careful not to damage it. Gently place the seed into the hole and lightly cover it with dirt from the pellet. Now that you have started the germination process, your seedling will come above ground within two weeks. The older the seed, the longer it takes for it to germinate.

3) Weed Seedling Sprouts

Perhaps the most exciting stage, your plant baby will come above ground in 1-2 weeks, with the average popping up in 5 to 7 days after planting. As your seedling comes above the soil, its shell might take a few days to fall off. It’s best to leave it alone, nature has the job covered. If it does not come above ground after about two weeks, the chance of success is dramatically reduced, and it’s best to try again. Even the best seeds have an 85% germination rate. When your seedling comes above ground, it is going to want to see a direct light source.

Avoid Common Mistakes

4) Lighting for Your Cannabis Seedling

Marijuana seedlings require a medium amount of light — enough to get energy to grow, but not too much light that to get burned. Leaving your seedling in direct sunlight will cause the leaves to curl, while too little light will cause the seedling to stretch. If growing outside, seedlings want to see a direct light source to stop them stretching. If inside, a sunny windowsill with more than half a day of sunlight works wonders. Otherwise, 24 to 30 inches from a grow light is an excellent supplement. Your seedling should not stretch more than 6 inches at most.

5) Watering Your Cannabis Seedling

For cannabis plants young and old, it’s best to use bottled, distilled, or filtered water as these are without chlorine. If using tap water, let it sit for 48 to 96 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp but not soaking wet. Overwatering is just as deadly as drying out!

Damping off happens when the seedling is in too moist of an environment. The young plant’s immune system is not strong enough to ward off a fungus that results in the plant rotting from the bottom of the stem. When this happens, the plant will bend over and die if not treated. To help fight the infection, lightly spray a 0.5% solution of hydrogen peroxide around the affected area. However, the best option is to avoid this by not exposing your seedling to too much moisture.

6) First Cannabis Seedling Leaves & Hardening Off

The first set of leaves to come above ground are called the cotyledons . These little leaves are packed with energy and will grow to about 1/4 in in size before eventually falling off. Your second leaves to emerge will be single blades and will be serrated, looking like regular pot leaves.

They will become several inches in length. During their growth your first actual set of leaves will appear. These are typically three blades. Around this time is when your plant is “hardening off”. You will notice that the stem will start to develop a thicker skin and harden off. As the leaves of the plant get bigger, they can gradually handle more sunlight, so move it into more direct light– the more light the better!

7) Transplanting Cannabis Seedlings

About 10 days after germination, when the baby cannabis plant has hardened off, roots will start emerging from the bottom of your seedling pellet and the plant is ready to be transplanted into a bigger pot. Be very careful not to damage the roots during this stage. Any stress will slow its growth.

Dig a small hole in your bigger pot for the seedling, sprinkle some rooting booster in the bottom of the hole then carefully plant the whole seedling pellet holding your weed baby.

Now bury so the base of its stalk is level with the topsoil. Give it a watering to set the roots in the ground, then hold off watering until you pick up the pot and it feels light in weight.

8. Separating the Girls from the Boys

At about 4-6 weeks into your plant’s growth , you’ll be able to determine the sex of the plant. You’ll want to separate and dispose of any male plants. This is an important step for growing marijuana because the female plants are more potent and valuable. You also don’t want male plants to compromise the growth of your female plants.

Why Do You Only Want Female Weed Plants?

Only female marijuana plants produce THC buds that are high in potency. You want to make sure your Cannabis plants are all female. If you have a male plant, it can fertilize the other female plants, and they will work to produce seeds instead of flowers and nugs.

It’s essential as a grower to know the difference between a female and a male plant so that you can remove the male plants before they contaminate your crop . Unfortunately, you have a 50/50 chance of getting a male plant when growing a plant from a seed from a nug.

There is a massive market for seeds that will only grow into female plants. But even these seeds are not a 100% guarantee you’re going to get a female plant. To ensure a good crop, you’ll want to germinate and plant many marijuana seeds and then separate the females from the males when the plants begin to show their sexuality.

How to Tell if a Weed Seed is Male or Female

As your plant matures sexually, it will develop between its nodes. Nodes are the area of the plant where the branches connect to the plant’s stalk. The distinguishing characteristics that will help you identify your plant’s gender:

  • Male Plants : Small pollen sacs will cluster in the nodes.
  • Female Plants : Stigmas will develop in the nodes. The stigmas can catch the pollen of male plants. Stigmas have hair-like veins that will extend from the sacs in the nodes.
  • Hermaphrodite Plants : These plants have both the stigmas and pollen sacs in their nodes. These are female plants that develop both sex organs when exposed to a lot of stress.

Once you can identify the sex of your plants, you’ll want to remove the male or hermaphrodite plants because they can negatively affect the harvest of your female plants. That’s why it is crucial to germinate and grow several cannabis plants to this stage to ensure you get at least one healthy female plant.

9) Grow Weed Plant, Grow!

Suddenly, before your very eyes, the plant will transform. She will grow in height and branch out, putting off leaves and a network of branches. It is your job as the grower to meet her needs so that she can reach her full potential. With a good grow kit, this means as much light as possible and lightly watering only when she is thirsty.

This is considered your marijuana plant’s vegetive stage. The goal in this stage is to keep her healthy and allow the plant to grow as big and strong as possible so that she can hold many, many flowers.

Step 1 – Pick the Best Marijuana Seeds for You

Cannabis genetics are important to consider when planning your grow. Most cannabis consumers are familiar with the idea of Cannabis indica vs. Cannabis sativa . They understand how an indica -dominant strain is typically more relaxing and that sativa -dominant strains are known for their abilities to energize the mind and aid your creativity superpowers.

However, many people don’t understand the difference between autoflowering cannabis and photoperiod cannabis , aka regular flowering cannabis. Understanding these two options makes a big difference when selecting a 1st time strain based on how easy it is to grow. For beginners, we love autoflowers !

Autoflowering Cannabis vs. Photoperiod Cannabis

The key difference between autoflowering and regular flowering cannabis is how (and when) the plant’s flowering cycle begins. Simply put, autoflowering cannabis automatically starts its flowering cycle, while photoperiod waits for the correct light vs. dark period (12 hours light / 12 hours dark) to flower.

Autoflowering is Easy for Beginners

By far, the easiest and cheapest plant to grow for beginner growers is autoflowering cannabis . It comes from the species Cannabis ruderalis . This type of cannabis flowers, as the name suggests, automatically.

Once the cannabis plant is a few feet tall, or about 30 days after she pops out of the dirt, she starts her flowering cycle. Autoflowering cannabis is typically ready to harvest in 80 days from seed— regardless of her light schedule. This means the autoflowering cannabis growing season is year-round! Autoflowering cannabis seamlessly integrates into your home and plant family. Make it easy on yourself and go this route.

We love these types of seeds so much that our Grow Kits include a $40 discount coupon on autoflowering seeds from our friends at .

Photoperiod Cannabis Can Produce More Marijuana

Commercially – grown marijuana or those grown by seasoned growers are typically regular flowering marijuanas plants. More specifically, they are photoperiod cannabis. These, under the right growing conditions, are the giants of the pot world– with the potential to grow 16 feet (or taller) and harvest 10 pounds of dried pot off a single plant.

This species of cannabis starts her flowering cycle when she starts receiving equal hours of sunlight and darkness. This means if you are growing this type of pot indoors, the plant needs to consistently receive 12 hours of light and 12 hours of darkness to release the necessary hormones to begin flowering. This is why many people that grow photoperiod cannabis indoors opt for grow tents or dedicated grow rooms.

Before flowering, these plants savor what is known as the vegetative stage. This is when the plant enjoys more hours of light than darkness. Indoors, this is typically 18 hours of light and 6 hours of darkness. During this phase and light cycle, a photoperiod plant will continue to grow in size without flowering.

Growing Photoperiod Cannabis Requires More Work and Investment

Growing marijuana outdoors, this specific lighting need is why photoperiod plants flower in the fall and can grow to such staggering heights. They grow all summer long in a vegetative stage until the start of fall, when there is less light, which triggers them into flowering. Indoors, a grower needs to control this light cycle to avoid confusing the plants. Addling light when the plant thinks it is nighttime can ruin a whole crop. Light leaks are a common mistake. If it’s your first time growing cannabis, this will be a bit more of a challenge to keep up. It’s also going to be a bigger investment to start growing, as well as a lot more work.

Take it from a seasoned grower: If this is your first time learning how to grow, autoflowering strains are more stress-free, cheaper, and easier to maintain. Autoflowering cannabis seeds are the best way to grow yourself some weed at home — without all the fuss.

Indica vs. Sativa Growing Styles

Cannabis ruderalis and photoperiod cannabis both have strains that lean towards either indica or sativa dominance. The experience post-consumption and their growth traits are the same for both photoperiod cannabis and autoflowering cannabis.

For example, Jack Herer Autoflower genetically is a predominantly sativa plant . This plant will grow larger and might take a little longer to finish than her indica-dominant counterpart. Indica-dominant plants, like Wedding Cake Autoflower , tend to stay relatively short, reaching 4 feet tall at most. They are squat, stubby little weed plants with wide leaves. Sativa plants tend to be tall, stretchy plants with thin, narrow leaves.

If your goal is to grow one small cannabis plant, you should grow some of the best autoflowering strains, such as OG Kush, Cheese Strains, Northern Lights or Girl Scout Cookies. Indica-dominant autoflowering cannabis plants typically grow to around 2 to 4 feet tall. This makes them great for growing in gardens adjacent to nosey neighbors!

Autoflowering sativa plants grow much taller. Many will grow past 4 feet, and some reach 6 feet tall. If you grow sativa-dominant plants outdoors, plan on sharing these amazing plants with your neighbors!

Step 2: Select Your Grow Location

Cannabis grows well in a variety of environments, and they are remarkably tough plants. As a grower, you just need to keep your grow space clean and let the plants do the work.

When learning to grow autoflowering weed strains, the number of factors that can go wrong dramatically decreases compared to photoperiod cannabis. If your goal is to grow a single cannabis plant, then the number of locations you can grow without risking your crop increases with autoflowers. Contrary to popular belief, you don’t need a $1000 grow tent setup to grow some good cannabis – all you need is sunlight and good water.

Growing Your Plant Inside

You can grow the best cannabis indoors or outdoors. A good indoor setup for weed provides total control over the growing conditions. Indoor growers have a lot of responsibility — you become Mother Nature! Your cannabis plants depend entirely on you to meet all of its needs – including light, humidity, airflow, temperature, food, and water. Unfortunately, it can be expensive to get all the right equipment, plus you must consider the cost of ongoing electricity.

Growing Your Plant Outside

Alternatively, you could grow your cannabis plants outside. This option is less expensive because nature does most of the work, such as providing sunlight. And cannabis plants love the natural sunlight because it boosts their immune systems. There is no replacement for the sun. If you are just getting your feet wet, doing a combination of indoors and outdoors is a great way to start.

There are some drawbacks to an outdoor plant, however. Growing marijuana outdoors isn’t as private as many people would prefer, and growers often have to contend with the risk of stolen plants, animal attacks, or the wandering eye of your neighbor, who is now working from home.

In summary, you’ll need to consider your budget. Weigh the pros and cons of growing pot indoors or outdoors before you start growing. Then, select the option that works best for you and your specific situation.

Growing Cannabis as a Houseplant

Autoflowering cannabis can be grown as a houseplant, just put her in the sunniest spot in your house and let her rip. This method of growing cannabis is best if you are just looking to grow and don’t have high expectations. However, that doesn’t mean you shouldn’t expect something.

With 4 to 6 hours of direct sun, you can yield a surprising amount of cannabis. And since the cost of starting with just a pot is just some soil, a seed, and the sun, the investment will for sure payout in the green.

Cannabis in a Grow Tent

People typically grow marijuana indoors in a grow tent or dedicated grow room. The goal is to optimize the plant’s environment and blast the plant with as much light as she can handle so you can yield the most amount of cannabis per square foot. Although, as most cannabis growers will tell you, locking a 600-watt HPS grow light in a 5x5x7 grow tent will give you more problems than you’d expect. Heat, humidity levels, airflow, and pest management practices are all things to consider and plan for. (Yes, indoor grows are just as likely to get bugs as outdoor.)

If you plan to grow in one of these environments, we suggest setting aside no less than a $700 budget for the tent, lights, fans, timers, and control boxes you will need, plus an extra $80 a month in power bills. Keep in mind this is a pretty hefty investment if you’re just looking to grow a small amount of cannabis. However, if you are looking to make some cheddar from the cheese you are growing, this is a good way to learn to grow your own sticky icky before scaling up. We all know that commercial cannabis will never be as good as homegrown goods grown with love and detail to attention.

Things to Consider When Growing Cannabis Outside

Autoflowering weed will grow year-round outside. As long as the temperature does not get below 43 degrees fahrenheit, your plant can survive. And when it does get cold, you can just bring her inside. Because autoflowering cannabis will flower no matter the light cycle, you can get up to 4 harvests a year outside on your balcony or in a garden. Plants grown in the winter will have a beautiful purple coloring to them by the time they are ready for harvest. Plants in the summer will grow bigger and bushier, reaching C. ruderalis full height potential of up to 6 feet tall and yielding up to 8oz of dried marijuana.

On the other hand, growing photoperiod cannabis outdoors is a one-time a year thing; she’s a seasonal crop. You put her outside in late spring; she grows all summer and then flowers once the days start losing light. Timing when this occurs can get tricky, depending on your latitude and how cold it gets. So plant a lot and clear your social calendar because those plants will run your life for most of the year.

Step 3 – Pick the Best Grow Light for Pot

Light is how your plant gets all her energy to convert the nutrients in her soil into more plant matter. So, the quality of that light is vital to your final yield.

If you grow indoors, you’ll need to think about your plant’s light source. Keep in mind, one of the biggest benefits of growing a single plant is that your plant won’t need much light. You can place your plant on a windowsill and have enough natural sunlight for it to thrive in many cases. However, if you’d like to grow your plant in a more discrete location, away from natural light, or have limited natural light, you’ll need to think about grow lights . In that situation, how to grow a small weed plant quickly becomes how to select the best lighting.

The general rule of thumb is that the more light you give a cannabis plant, the more you will harvest. Autoflowering cannabis plants like to have some dark cycle to do their nighttime activities; we suggest around 4 to 6 hours of darkness a day.

Growing Weed with the Sun

The ultimate, cheapest grow light for cannabis is the sun. Sunlight is the most powerful light us earthlings have access to, so i f you are lucky enough to live somewhere that allows you to take advantage of the giant fireball in the sky, we suggest you use it. Even just as little as 4 hours of direct sunlight will do wonders for a small autoflowering pot plant.

When growing marijuana outdoors in full sun your plant can yield up to 8 oz. Cannabis grown outside will always yield more and be more potent than any indoor grow light. You just can’t beat the power of the light spectrum of natural sunlight, and cannabis plants love it!

If you opt for natural sunlight and you aren’t using autoflowers, you’ll need to ensure that your plants receive at least 18 hours of sunlight during the vegetative stage of their growth. Unfortunately, that means unless you are growing during the correct season and in the right area, this may not be obtainable without supplemental lighting. In other words, even if you are growing outdoors, investing in an LED lamp for those cloudy and or ‘short’ days might be a good idea.

Growing Weed with LED Lights

LED lighting is a great option for giving your plant everything she needs or just an extra boost. Natural colored LED lights using a COB LED are our preferred choice because you can see the correct color of your marijuana leaves and most closely resembles natural sunlight . While the pink and purple LED lights do a fine job, they also miss specific spectrums that contribute to the robustness of your plant. We’ve found that a more complete light spectrum develops a more complete terpene profile and produces more hearty plants.

For a single plant, a 75 watt COB LED grow light is ideal. LEDs are a popular choice for growing marijuana and are perfect for producing healthy marijuana buds on a single plant. They are also optimized to prevent your plants from receiving too much light, which could cause a condition called ‘light burn.’ Another huge benefit of LEDs is their cost. The bulbs are inexpensive and readily available. Best of all, they don’t require much energy, so you are not going to spike your electricity bill. The casual observer will never suspect that you are growing marijuana indoors just by seeing the light shining from your home.

We discourage using HPS grow lights mostly because they tend to generate a lot of heat for indoor use. Plus, HPS lights can easily burn cannabis plants. For hobbyist growers, LED technology will grow great buds at a significantly reduced electricity cost.

There are, of course, other cannabis lighting options, but for a single plant, they can be much more than necessary. However, it is still a good idea to research your options to make an informed decision based on your wants and needs.

Step 4 – Picking a Pot Size for Autoflowering Weed

Some say cannabis got the name ‘pot’ because early growers would move the pots they’d planted in as needed. With marijuana restricted and illegal in some places, people who grew (and in some cases still grow) had to be creative! The pot provided the freedom to create the best environment depending on what was available.

This is even more the case with autoflowers. Autoflowering cannabis is a really smart plant! She can sense her environment and grow accordingly. Much like a goldfish in either a fishbowl, aquarium, or ocean, your plant’s size depends on the size of its container. An autoflowering seed has the same potential– it just depends on what you plant it in—the bigger the pot, the bigger the plant (which means more pot).

To help you decide how much autoflowering cannabis you’d like to grow, we made our grow kits in three different sizes:

If you want to grow a tiny little cannabis plant that will be perfect for your desk or just as a little experiment for the kitchen windowsill, a ½ gallon pot will grow an autoflowering marijuana plant less than 2 feet tall. These little plants are adorable! How much you harvest will largely depend on the genetics and how much light you give the plant. It will need more frequent watering due to its small size.

A 2-gallon pot will support a small marijuana plant that yields about 4oz of pot. This size provides more space for your cannabis plant’s roots. When growing outside during the summer using organic soil, water every couple of days, especially on hot days. Your cannabis plant will stay a reasonable size.

This size is the gold standard for autoflowering cannabis plants. If you go much bigger, you start to get diminishing returns as autoflowering pot plants don’t grow massive root structures. With a 5 gallon pot, your plant will grow to her genetic potential of about 4 or 5 feet tall on average. A 5 gallon pot is a great size for growing outside under direct sun or indoors inside a grow tent.

Step 5 – Selecting the Best Grow Medium for Pot

When thinking about how to grow a small weed plant, one of the most important things that should be on your mind is what you will grow the plant in. Your plant will need a medium that provides the required nutrients for developing picture-perfect buds. And, just like grow lights, there are numerous options for best grow mediums. Each medium will have its own set of requirements for best growing conditions, such as how often you’ll need to water, but in the end, every option is equally capable of producing high-yielding cannabis plants.

Super Soil is Superb.

The most common (and easiest to use) grow medium is soil. Ideally, you should use well-composted organic soil rich with nutrients designed for growing cannabis and formulated for commercial cannabis specifically. A Pot for Pot’s Superb Soil is an excellent example of this. Superb Soil is what professional growers refer to as “hot soil.” This means it has a surplus of bioavailable organic nutrients that are alive and working for you!

It’s also the plant equivalent of rocket fuel, so adding nutrients isn’t really necessary. If you do not start with soil that has been optimized for cannabis growing, you’ll want to ensure that the soil includes perlite so that it drains well. Mixing your own super soil for cannabis requires over 17 ingredients and some heavy lifting when mixing it all. If you would like to learn how to mix your own, download our full guide below.

Save Money – No Tent Needed

Organic Cannabis Soil Recipe

Avoid Common Mistakes

Hydroponics grows are hard.

You could also go soilless and buy vermiculite, coco coir, or rockwool. These mediums require constant feeding and flushing to keep the root zone moist and free of nutrient buildup. While these may be more expensive than soil, they come with some advantages, including yielding a lot of cannabis. Hydroponic growing is a super fun and rewarding process that grows great cannabis.

A disadvantage of hydroponic growing, though, is that they do not contain nutrients for your plant, so you’ll need to carefully measure and distribute the proper nutrients in the right proportions and at the right time. Worst of all, one over-feeding can ruin a whole crop. You can produce very high yields with this method, but there is a steep learning curve, and it is a bit expensive (both time and money-wise) for a single plant. If this is your first time, we suggest keeping it simple and letting the plant do the hard work in an organic soil mix.

Step 6 – Select Your Nutrients for Marijuana

With marijuana, you want to use specific nutrients that help your plant thrive during the different stages of plant growth. Choose nutrients formulated for the particular medium you’re using – that doesn’t mean Miracle Grow. (Please don’t use Miracle Grow aka Miracle No-no) Certain nutrients will only work in hydroponic systems, while others work best with soil. There are even organic nutrients if you are so inclined!

No matter what nutrients you use for your pot plants, we suggest using ⅓ of the strength of whatever the manufacturer suggests (hint: they want you to use more than you need so you buy more faster). Marijuana plants can be very sensitive to too many nutrients. Lock-out from too many nutrients results in stunted, stressed plants that may flower too early.

Watering Cannabis

You’ll also need to consider the pH of your water source. Water is an important factor to consider in your plant’s growing conditions because it is how nutrients get to your plant. If the pH is incorrect, your plant cannot absorb those nutrients – think of a square block moving up a round pipe. The pH should be appropriate for the medium that you choose. When growing in soil, the pH of your water should be slightly acidic, between 6.5 and 7.0 ideally. This allows the plant to absorb the nutrients in the soil efficiently. (Growing hydroponically, your pH should be lower, preferably in the 5.5 – 6.5 range.)

To be honest, nutrient and pH levels can be complicated and a definite hassle when you only want to grow a single plant. A much easier solution is a Pot for Pot Grow kit . Not only are these kits designed to make growing a single plant simple and easy, but they also provide the best organic nutrients and growing medium for your plants so that you don’t have to spend any time on this step.

All you need to do is add water (in that sweet spot pH range) and let your plant do the heavy lifting. As you get more experienced with growing cannabis, you can start adding nutrients to maximize your yield. But, if you are just trying to grow one amazing cannabis plant, a Pot for Pot does a great job of empowering you to grow your own. You simply need to know how to follow instructions, provide sunlight, and add a little water!

Step 7 – How to Germinate Cannabis Seeds

Autoflowering cannabis can only be grown from seed. There are plenty of ways to germinate a seed, but a seed germination kit is the easiest option. We like the method of soaking your seed in water for up to 48 hours; when it sinks, or you pop a tap root, she is ready to come out. And no matter what, after 48 hours, transplant your seedling to your germination medium.

Another easy germination method is to place the seed inside a damp paper towel. Then place the moistened paper towel inside a clear Ziploc back and close the bag. Place the baggie in a warm environment to help the seed germinate.

After one to three days, the seed should have a tiny white tail growing out of the seed. If the seed hasn’t sprouted a tail within five days, the seed isn’t viable.

Jiffy Pellets

To use a Jiffy Pellet , moisten the peat-based medium, insert your seed, and water as needed. Once your seed sprouts, you can place the entire medium into your pot for easy transplanting.

These steps produce the best results when germinating seeds:
1. Soak seed in a cup of pH neutral water in a dark place (like a kitchen cupboard) for 24 hours
2. Prepare jiffy pellet by soaking in pH neutral water
3. Gently squeeze any excess moisture out of the jiffy
4. Use your seedling or scissors to poke a ¼ inch hole into the expanded jiffy and plant the soaked seed
5. Place planted jiffy pellet in a seedling cup under direct light until your seedling makes an appearance topside.

Plant Your Germinated Seeds in Seedling Pots

When germinating cannabis seeds, you’ll want to germinate multiple seeds. This is critical because not all seeds will germinate, and you can’t determine which seeds will be female or male until the plant has grown. While male plants produce pollen, they do not flower, which is what you want. So you’ll want to ensure you’ve grown a female plant.

Once your seeds have germinated, you’ll want to plant these seeds about one inch deep into your planting soil in seedling cups. If you don’t have seedling cups, you can use plastic cups. You’ll want to poke holes in the bottom of the cup for drainage.

Then place your seedling cups where they can get direct sunlight or from a grow light. You’ll want to water your seedlings by keeping their soil moist. The best way to water your seedlings is by misting them with a squirt bottle . Within a couple of days, your seedlings should sprout a few baby leaves.

Getting your seeds to sprout is one of the most challenging steps of the growing process. If you’ve made it this far in the growing process, then you’re in a good spot. Now you just need to provide the necessary water and light to help your tiny plants grow.

Step 8: The Cannabis Vegetative Stage

Once your marijuana seedling develops a pair of leaves, she has officially entered the vegetative stage. This is when pot plants have the singular purpose of growing bigger and stronger in preparation for the coming flowering stage.

During the vegetative stage, marijuana plants need plenty of light . You’ll need to give them around 18 hours (or more) of light during this phase. Also, ensure that the temperature in your grow room (or wherever you are growing your plants) is a bit warmer than room temperature. That means between 68°F and 82°F. The long hours of light and higher temperature mean your cannabis plants will need plenty of water , so monitor the moisture level and adjust accordingly. You don’t want your plants to be too thirsty. But, overwatering is more deadly than under-watering.

How well your plants grow during this stage will directly impact their yield. Smaller plants will yield fewer and smaller buds. Bigger plants, however, are stronger and can support denser,

more plentiful buds. So, remember to provide the best care for your plants in the vegetative stage!

Your cannabis plant will need to grow during this stage for at least three weeks for it to reach its sexual maturity. If you’ve given your plants enough light and nutrients, the plant leaves will be dark green and won’t have any brown spots.

Transplanting Your Young Plant into its Flowering Container

At this point, your plant is ready to be transplanted into its final flowering container. Your final container is a personal choice based on how big a plant you want to grow . Whatever size container you choose, you’ll want to fill it with about one gallon of soil per foot of anticipated plant growth.

You may want to add some bloom fertilizer to the soil to give your plant a growth boost. Bloom fertilizers have higher phosphorus and potassium levels and lower nitrogen, which provides ideal growing conditions for your young plant.

Be very gentle when transplanting your plants into larger containers because the roots can damage easily. To remove the plant from the seedling pots, squeeze the bottom sides of the cup to help loosen the roots and soil. Then gently flip the plant into your hand and be careful to support the root mass as you place it into its new container.

Step 9: The Cannabis Flowering Stage

When flowers start to form, you’ve entered the flowering stage. Only female plants produce flowers. The first sign is thin flowers with white hair-like structures called pistils. Those little pistils are pre flowers and will eventually produce buds – which you can eventually consume. This important phase in the life of your pot plant lasts until you harvest the mature buds. Here’s what happens during this stage:

Your plants will get large and bushy. You may want to ‘train’ them by trimming and/or bending the leaves to form a flat canopy on top. This pruning allows light to reach all parts of the plant for maximum yields. Pruning is an advanced technique, so you’d want to read up on it first before trying it.

If you did not purchase feminized seeds , or you are unsure of the sex of your pot plant, you’ll need to confirm that it’s female as only female plants produce flowers.

How can you know if your pot plant is male or female?

Easy. Just look at the junction of the branches and observe whether you see wispy white strings emerging from the buds. If these wisps (pistils) are present, that plant is female. If pistils aren’t present, then what is growing is a pollen sac, and the plant is male. Male plants do not produce the buds that you wanna consume. Female plants are prized for their ability to grow the yummy flowers we all love.

Depending on what type of cannabis you are growing, you may need to change the light schedule to initiate the flowering stage. If you are growing photoperiod cannabis, you will need to increase the amount of darkness your plant receives to 12 hours daily. That means 12 hours of light and 12 of darkness each day. Respecting the light schedule is an absolute necessity for regular flowering cannabis seeds. Autoflowering marijuana doesn’t depend on a change in the length of daylight hours to start flowering, so this step is unnecessary with autoflowering seeds.

For all types of marijuana, you will want to consider adjusting the temperature. The flowering stage requires cooler temperatures, so keep it between 64°F to 78°F. Ideally closer to 65 degrees Fahrenheit if possible! If you used any nutrients, make sure you’ve stopped and are providing plenty of water. This helps with taste, aroma, and potency when it’s time to enjoy your cannabis.

You’ll need to carefully monitor your plants for the next eight to nine weeks as they grow. Watering during this stage means adding tap water to the soil whenever the top three inches of soil are dry. Flowers will finish blooming around the end of eight or nine weeks in a 12/12 light cycle.

You’ll also want to keep your plants in a grow space that has airflow. Air circulation is critical to the plant for photosynthesis. If growing outside, this won’t be an issue. If growing indoors, you’ll want to ensure the room has adequate air movement.

The most important thing to remember about this stage is to watch your plants. Marijuana plants in the flowering stage are rather sensitive to the conditions under which they are growing. Look for signs of a problem, such as brown leaf tips. This could signify a problem with watering, lighting, or nutrients.

Step 420: How much Cannabis will you Harvest

Harvesting pot at home is really exciting! You watch weed plants develop and blossom amazing, pungent flowers. Soon, you’ll start to wonder when you can reap what you’ve sown. But how do you know when to make the cut? How do you know when to harvest your weed?

Cannabis gives clear signals as to when she’s ready to move on to the most exciting time of her life — consumption!

Two things to look for when determining if your marijuana flowers are ready to harvest:

1. The color of the stigmas (the hair-like structures coming off the buds). You want 80% or more to have turned from white to orange/red/brown.
2. The color of the trichomes (the yummy crystals on the buds). You want these to turn from clear to milky.

You will know the buds have matured from the color of the stigmas. You will see wispy white hairs growing out of the buds. These wisps will change color gradually until they become amber at the peak of maturity. This is a great first sign to look for. Cannabis can be tricky, though, and can keep producing stigmas way past her prime. This tendency is why it is important to look at more than just the stigmas for cues.

Your plant’s trichomes’ color and shape are a more reliable way to gauge readiness for harvest, but this will often take magnifying lenses to see properly. You’ve reached peak THC when the trichomes are cloudy in color and have rounded mushroom-like shaped heads. Premature trichomes have flat heads.

A good time to harvest is when most trichomes are cloudy or milky in appearance, with one or two trichomes appearing amber. Too many amber trichomes, and you’re past peak THC harvest. At this point, a significant portion of the THC is now CBN (a cannabinoid that relaxes and calms the mind). So, you will still get some medicine from over ripe buds– just a different cannabinoid.

How do you harvest the buds?

Simple, take some scissors (there are some in the a Pot for Pot Complete Kits ) and start cutting. First, remove fan leaves and pre-trim. Extra leaves hold water, and we want our weed to dry efficiently! You can leave the fan leaves but know that drying will take longer. Grower’s choice!

Sometimes, the top-most buds are ready before the bottom buds. This is a normal occurrence because of the relative light exposure between the top and bottom of the plant. In these cases, harvest in stages– take the top buds first and circle back for the bottom buds in a few days.

Using your scissors , cut each branch just below the bud and hang it upside down (buds facing downward) in a dark closet for a few days until dry. If you lay your buds flat to dry, they will get smooshed and dry unevenly. It’s best to have humidity levels around 50%, temperature around 65 degrees fahrenheit. Drying can take up to a week, but most finish in about 5 days.

Test for dryness by bending the stems– when they snap instead of bend, it’s time to cut the buds off! Don’t test for doneness by touching the buds because if the buds are still wet, they’ll get smooshed. Finally, give them a proper trim job and store them in glass jars. It’s best to keep these jarred-up nuggets out of direct light, as sunlight can bleach your buds. Open the jars everyday day to burp them for a few minutes (this allows fresh oxygen in and other stuff out.)

You can smoke your weed as soon as it’s dry. Some impatient growers throw a few fresh flowers in a brown paper bag for two days (a flash dry method) and then grind them right into a rolling paper. The curing process really just brings out the flavor, terpene profiles, eliminates chlorophyll and makes for a smoother smoke. We recommend curing your buds if you plan to smoke or vape your harvest. You can cure for ten days, two weeks, four weeks, two months, or even up to 6 months – how much patience do you have? (This is coming from some impatient stoners but, hey, we appreciate a quality experience!)

FAQs about Growing a Small Weed Plant

What’s the difference between feminized and autoflowering seeds?

Autoflowering seeds bloom automatically without having you do anything, while feminized seeds need a change in the light cycle to start the blooming process.

What pot sizes should I be using for Autoflowers?

The ideal pot size for autoflowering cannabis plants are 0.5 to 5 gallon pots. The size of the pot determines the size of the plant! Bigger pots = bigger plants.

Do I need to add nutrients to my marijuana grow?

Not in an organic, general-purpose Superb Soil mix! It has a complete nutrient load for an autoflowering plant. You should add nutrients if you’re growing in hydroponics or any nutrient-less medium.

How much light should I give my autoflowering plant?

Autoflowering cannabis is great because she can grow under any light conditions. Ideal conditions outdoors are a minimum six hours of direct sunlight. When sunlight is not available, supplementing with a grow light (or a high wattage regular light) will keep your plant happy. We recommend giving her 20 hours light / 4 hours darkness each day for those growing entirely indoors.

How Do You Manage the Plant Smell Right Before Harvest?

Just before harvest, your plants are going to start smelling very distinctive. Depending on if you want your neighbors and friends to smell your sweet stinky weed, you may want to try different products to manage the smell.

The most common method to manage the smell is using a carbon filter. A carbon filter utilizes mesh tubes filled with charcoal so that when the fan pulls the air through, the charcoal absorbs the particulates and leaves the air smelling clean and odorless.

Why is My Weed Plant Not Growing Taller?

Unfortunately, many factors can stunt your plant’s growth:

  • Watering and Pot Size : If you overwater or underwater your plant, it will affect the development. If seedlings are in too big containers, they can drown in overwatered soil. Make sure your container and watering are appropriate for your plant’s size.
  • Nutrient Toxicity : If there are too many nutrients in the growing medium, the plants will react. The leaves will have burnt tips on dark green leaves. If the leaves turn yellow, brown, and then crispy, the soil is deficient in nitrogen and needs more nutrients.
  • Temperature : If temperatures are too hot or cold, it can also stunt growth. Leave tips will turn up or curl if temps are too hot. It’s essential to keep the growing environment between 72-79 degrees Fahrenheit.
  • Too Much or Too Little Light : Both too much and too little light can also affect your plant’s growth. If the plant has too much light, then the plant’s leaves will curl or appear burnt. If this happens, you’ll want to move your lights up or adjust your plant’s position to direct sunlight.

Can a Weed Plant Grow Forever?

No. Cannabis is an annual flowering plant, which means its life cycle is only one season. So your plant will grow, flower, and die. Some plants have several harvests before their cycle ends, but you will need to start again once it completes its life cycle.

Some growers can force a cannabis plant to revert to its vegetative stage, but that’s a more complicated process. For beginners, you’re better off collecting the seeds from your plant and germinating your seeds.
