What is the best way to germinate cannabis seeds?

This article explains how to correctly germinate your cannabis seeds, covering everything from optimum temperatures, to potting your seedlings and transferring them outdoors (or inside under lights).

The best way to germinate cannabis seeds requires only two saucers or plates and some moist tissue. Here is a step by step guide.

Warning!
Unfortunately, regulation and implementation in respect of cannabis seeds often differ from country to country. For this reason we advise you as a matter of urgency to make inquiries about the regulations to which you are subject. Read the complete disclaimer here.

Step 1. The setup – How to germinate cannabis seeds

Line the bottom of the first plate with a few layers of wet tissue and drain any excess water from the plate.

Seeds should be placed on top of the tissue, allowing each seed as much space as possible.

Place another few layers of moist tissue on top of the seeds, again allowing excess water to drain off.

Lastly, cover everything with the second plate, upside down, to form a ‘clam-shell’ shape – this will create the dark, moist environment necessary for germination.

Step 2. Germination – How to germinate cannabis seeds

Place the plates somewhere warm (21ºC) and away from direct light.

Check the seeds every day to ensure that the tissue does not dry out. Spray the tissues with water if necessary.

Within a few days some or all of the seeds should open and put out a root. It is common for cannabis seeds to open within 72 hours of being put in the germination medium. Less commonly, some seeds may need up to 10 days or even two weeks to open and put out a root.

When the first few millimetres of root have emerged from a germinated seed, each one should then be carefully transferred to a small container of growing medium (soil, coco-fibre or rockwool).

Step 3. Potting – How to germinate cannabis seeds

Make a hole in the growing medium that is about twice as deep as the seed is long, so that each germinated cannabis seed sits 2-5mm below the surface.

Place the cannabis seed, root first, into the hole and cover with a small amount of growing medium – just enough to block light, not enough to obstruct the seedling when it emerges.

Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.

Step 4. The seedling stage – How to germinate cannabis seeds

New seedlings should be given access to bright light from the time they emerge. Care should be exercised in the first week or two, as seedlings are still quite delicate.

Seedlings intended for outdoors should be acclimatised to direct sunlight by placing them on a windowsill inside the house and increasing their exposure to direct sunlight by an hour or two per day.

Seedlings intended for indoors may emerge into an artificially lit environment with no problems. If using HID lighting, seedlings should be kept a minimum distance of 50 to 80cm from the bulb. If using fluorescent light, seedlings can be kept a normal distance from the tube/bulb.

Laws and regulations regarding cannabis cultivation differ from country to country. Sensi Seeds therefore strongly advises you to check your local laws and regulations. Do not act in conflict with the law.

Hi, Once seeds have sprouted, how long can or should you leave them to grow under 24 hr lights before moving to your outdoor garden?

Good afternoon Ken,

I hope you’re having a great day.
For the vegetation process, a light schedule of 18 hours of light, and 6 hours of darkness is preferred. It would be best to get plants acclimatized to outside by placing them in a window, or under direct sunlight for a few hours a day.

Thanks again, and have a great day!

Hello everyone, all these suggestions are wonderful but I think a lot of you make it sound a little overwhelmingly. I’ve been very successfully cultivating for decades and I’ve always just placed my seeds, be it 1 or 100, in between 2 folded sheets of tissue which I’ve made wet with tap water. I then place them on a tray or plate in a warm dark area , such as an airing cupboard and leave for how ever long they take usually, 12 to 24 hours. The ONLY thing I do which takes effort is PH balance the water I germinate them in and I’ve only lost 5 seeds in nearly 40 years .

Good afternoon Paul,

I hope you’re having a good day,
Thanks for sharing your experiences with germination. pH balancing is a great tip You also might be interested in our new Jamaican Pearl Feminized Grow Report

Thanks again, and I hope you continue to enjoy the blog,

I lightly score my seeds by shaking them inside a rolled up piece of sandpaper – sandpaper side on the inside before leaving them in a cup of water for a few hours to hydrate. I then place them between wet (good quality) paper towel per instructions above. I find using an old plastic takeaway container with a heatmat below keeps the humidity high and with good end results.

Good morning Jonny,

Thanks for sharing your methods for germination with us, the heat mat and low-humidity are great tips!

Thanks again, and I hope you continue to enjoy the blog,

I have found out that the best and fastest way is to take a glass of clean/filtered water and place the seed right on top of the water (floating – NOT immersed in it!). If the seed is viable it will sprout in no more than 48 hours. Right after that you plant it in your pot/soil etc and you’re done.

Good morning Mary Jane,

Thanks for your support, and for sharing your experiences with germination!

Have a great day!

What happend if they sink I had em sink they came out fine

Are you saying they sprout in the glass of water and don’t “drown”?

Take aluminum foil flatten it out and put on top of your dirt it detects planes and grow it just like a tomato plant

Good morning Tammy,

Thanks for getting in touch with Sensi Seeds, and sharing your germination method with us!

Thanks again, and I hope you continue to enjoy the blog.
With best wishes,

Detects planes? Like magnetic? I’ve always has best success 24-48 hours soaked In water, spring water if possible. Usually do this in a shot glass, once they pop I’ll take a paper towel fold so it’s 2 layers then fold once more so you know where center is. Dump the seed in the middle of the edge and the true center (reason we folded a 2nd time)as well as the water just enough to saturate the paper towel. Do not soak! Carefully with the seed in the middle using sterile tweezers turn so the tap is growing down. This will prevent circling and tangling if doing multiple seeds. Now you can fold the other half so your seed will be “sandwiched” between 2 layers. At this time carefully take a corner and the waters attraction should keep your paper towel from unfolding but just in case be gentle. Holding it from 1 corner you can dangle it over a cub or the original shot glass so any extra water runs off. Now take a standard zip or press n seal sandwhich bag and slide your napkin in Carefully . REMEMBER which way was down! Work the air out making jt flat snd seal. Find a temperate dark area around 70°. A cabinet works we’ll as your going to prop it up with taproot facing downwards. Now just close it up and wait in 24-72 hours checking once a day. In rare cases you could have a 1/2″ tap root in the first 24 hrs some may take 4-5 days. Once the tap is about 1/2″-3/4″ long its ready for transplant into its first small pot. With this paper towel method I typically have 100% success.

Can you leave your seed to develop longer roots in the germination phase and can this make them better to grow or is a big no no?
Last year, I had 2 seeds that had really long roots with lots of secondary roots coming out when they were planted, one of which died after a couple of weeks and the other grew into a huge plant.
The other two seeds only had a short germinated growth and both died almost immediately after planting so not sure what I can learn from this…lol

Appreciate any thoughts and advice

Unfortunately, legal restrictions mean we can’t answer grow-related questions or give grow advice on this blog. However, other readers of this blog will often answer questions like yours.

Please check out the following articles on our blog which I think you may find of use, and I hope you continue to enjoy the blog!

With best wishes,

How often do you water and how wet should the plant be? Please.
Also if they are outdoor plants do you need to keep them covered with clingfilm for a wee while or do you just hope for the best. Thanks

This article, about how to water cannabis plants, should answer your questions. I can’t help you with the clingfilm one though, as it depends on the climate. Good luck, and happy gardening!

With best wishes,

Just drop the seeds in water, they will sprout , don’t have to use a towel and check it all the time , drop it in the water , let it float then it will sink and the root will grow out ,let the root get 1/4 inch and plant it where it’s going to grow , 8 hours sunlight starting as soon as it is out of the soil. Always grows great , don’t have to transplant from cup to gallon to bigger and bigger , if it’s growing outside put it where it stays , always does just fine.

Good afternoon Graham,

Thank you so much for sharing your experiences with germination.

Thanks again for your comment, and I hope you continue to enjoy the blog.

Have a great day!

I recommend this article to all breeders and cultivators who plans to germinate seeds and to some who don’t know how to germinate seeds, this article has the best and perfect ways on how to do it.

I have large bay windows at my condo which get about 11-12 hours of light per day. They are tinted but warm. I grow other indoor plants there perfectly. Is an ok place for my pot plants?

This sounds like a great place for all kinds of plants! I recommend you have a look at autoflowering varieties, as otherwise light pollution may negatively affect the flowering cycle. Good luck, and happy gardening!

With best wishes,

5 common mistakes when germinating cannabis seeds

Although the germination of cannabis seeds is a relatively quick and easy process, it is crucial to take into account a series of important factors in order to obtain as high a germination rate as possible. In addition, it’s in our interest that the seeds germinate as quickly as possible, and especially if we want to avoid problems like fungal infection or a low germination rate.

In our article on how to germinate cannabis seeds we explain step by step what you must do to achieve successful germination. Today we will take a look at the main mistakes made during this process, some simple errors that, as we will see, can easily be solved. Let’s see where many growers fail to germinate their seeds, it’s a great way to learn what not to do if we want to make the most of our seeds.

A germinating cannabis seed

Letting the germination medium dry out

By placing the seed in a moist culture medium, it begins a series of reactions that will lead to germination in a few hours or days. Whichever substrate we choose for germination, we must ensure that it never completely dries out, because as the seed stops absorbing moisture, it’s likely that the seed will cease its activity and never germinate. Cialis for Erectile Dysfunction http://valleyofthesunpharmacy.com/cialis/

For this reason, it is advisable to check every day to make sure the germination medium remains moist, especially if a heat source is used to achieve a higher temperature and therefore a better germination rate; the heat will cause the substrate to dry more quickly, something that must be kept in mind to avoid nasty surprises. In case of hydroponic cultivation it is always better to germinate in rock wool cubes, which of course must always remain moist.

The paper towel should never dry out once germination begins

Leaving seeds to germinate for too long

Another common mistake, in this case when germinating in kitchen paper or similar, is to let the seed germinate until the cotyledons appear. If we do this, then the subsequent transplant is very difficult, and it is very likely that we’ll damage the root in the attempt. Additionally, the longer the root is exposed to air and light, the more damage will result, so it is preferable to transplant it before this occurs.

To avoid problems, it is best to plant the seeds when the tap-root measures approximately 1cm, or 2cm at the most. This will make it much easier to transplant and we won’t harm the development of the roots, which can be expand into the new growing medium without setbacks. Phentemrine diet pills http://kendallpharmacy.com/phentermine.html

Direct germination in soil

This is a common mistake that usually results in non-germination, especially if the substrate hasn’t been previously watered before sowing the seed but is watered afterwards. By planting the seed directly in the substrate, we run the risk of it being buried too deep, made worse when we irrigate the growing medium post-sowing.

To obtain much better results, first germinate seeds in kitchen paper, jiffy pellets or peat plugs used for rooting cuttings and then transplant them to the soil or to a pot once the small seedlings have been born. Another benefit of this method is that we can germinate a large number of seeds in a very small space, such as a small greenhouse, which will make it much easier to provide the correct temperature and humidity.

Temperature and humidity for germination

Cannabis seeds germinate correctly with relatively high temperature and humidity values. It will be necessary, especially during some seasons of the year, to use some source of heat to get a temperature of about 26-28ºC. For this purpose there are many options on the market, such as thermal cables or heated greenhouses. The latter are particularly interesting because they also provide the perfect high humidity environment for seed germination.

The ideal is to maintain the germination medium at about 26-28ºC and at 70% relative humidity. Lower values ​​will result in a slower and less successful germination, while higher values ​​can bring fungal or rot problems.

A heated greenhouse is perfect for germinating seeds

Planting the seed incorrectly

If you look closely at a cannabis seed, you will notice that it has a slightly oval shape, ending in a point at one end and forming a small “crater” at the other end, which is called the crown. When planting your seed (whether it’s a seed that you want to germinate, for example, in a jiffy, or a seed already germinated on kitchen paper that you want to transplant) you must keep in mind that this crown should always be facing upwards.

So, you should plant the seed with the tip down and the crown uppermost and facing you. Once the seed germinates the crown will serve as a hinge, so that the seed will open at the tip and let out the root. In case of placing the seed incorrectly, the tap root will grow upward and the seedling downwards, which should be avoided at all costs because it is likely that the seedling will not be born.

Planting at the incorrect depth

Too often the seed is buried too deep (a problem that we have already seen in case of watering after planting the seed), so the seedling may never emerge. In the other case, if we sow too close to the surface, we can find that the seed germinates well but the stem grows weak, bending and not allowing the seedling to develop correctly.

To avoid these problems it is be best to sow the seed at about 2cm depth. In addition, we can cover the lower stem as the seedling grows, so that it gains stability and produces new roots along the length of stem we have buried. In this way we can accelerate the growth of the plants.

We should plant the seed with the root downwards

Planting several seeds in the same pot

Although it may be tempting, germinating several seeds in the same container is not usually successful. In addition to the difficulty of correctly planting several seeds in the same pot, once they are born they will compete for the little space available for their roots. Having restricted root growth does not suit cannabis plants, which will grow more weakly and with greater internodal distance.

In addition, the scarce space between the plants will also mean they will compete for available light, something not recommended if we want to get the most out of each plant. The plants will produce very little lateral branching, and will center their growth on a weak main stem, with too long an internodal distance, factors that usually affects negatively on the final yield of buds.

We hope that this article will help you avoid problems when germinating your seeds, it can be very frustrating to start a grow with all the enthusiasm and excitement, only to run into problems straight away! Do not hesitate to leave us any doubts, comments or your own tips and tricks, we’ll be happy to answer you.

I quit reading long back when the initial 100 seed results were reasoned. I’ll likely be missing many points observed. Simple opinion, for better than 25 million years of natural survival this plant has recreated itself for man to adapt to its uses in a very short 10,000 or how ever many years there’s been somebody crapping In a watermelon patch Surely it knows its way around a 2cm [email protected]&?ing hole surrounded by its predecessors environment. I would think genetically it knows what the !(@& to do. Especially if you are using a “Feminized seed”. Now, surely many observations have been made justifiable or not the laws of average are easily debatable, but I believe that the laws of average have established the standards many moons ago friends. Maybe I’ll fill up a kiddie pool 4ft Dia. @6 inches deep perlite and drop a 100 seeds through a pine bow from 6 feet high and then document the seeds position when it’s at rest in the perlite.. . I’m Extremely new to cuktuvating cannabis, my 2nd year. My first year turned out peesonally satisfiable at best simply because I planted shark cookies. I germinated in a paper towel, from there I rested the seed however it rested in a tub of perlite with an aquarium bubbler, also a circulator moving a solution of compost tea through the roots for 2 weeks, then put them in a small crawl area with a fan and a few lights for another 45 days, and then moved them to a bucket and put outside for the next 3 months and then brought back inside for another 2 weeks. So any opinions that we all have are open for discussion, but the only resolution for judgement is our own environmental abilities to nurture the development of variable genetics. Happy gardening friends..

Hi and thanks for your comment. We’re happy that your first year of cultivation was a reasonable success, we hope that this year will be even more so! Germinating seeds may seem like the most natural and easy thing in the world, and that’s how it should be, but it’s amazing just how many people fall at this first hurdle, and when the seeds are not particularly cheap, as in the case of cannabis, it becomes even more nerve-wracking, especially for beginner growers and those who have no basic experience of growing other plants like vegetables, flowers, etc. There’s no real substitute for experience in this game, and the more seeds we pop, the more confidence we get. Thanks again for your comment, best wishes to you!

Jubjub 2021-11-19
Hello Good day I have some that looks like stale might be more than years old seeds. It was a given to me by a friend and I doubt it was preserved properly in proper containers. Will it still germinate?

Tim 2021-11-24
Hi, thanks for your comment and question. The older the seeds are, the less chance they will germinate, and if they weren’t stored in good conditions (dry, cool, stable, e.g. in the fridge) then the chances of non-germination become even greater. You can try a few things to help improve germination rates, for example, the application of fulvic acid and/or gibberellic acid will give older seeds a better chance of germinating. Try germinating a few of the seeds in the normal way and then if you don’t get success I’d look at using one or both of the compounds I mentioned. I hope that helps, all the best!

I have germinated five seeds of different stains, all paper towel method. All sprouted.. All healthy.. All put in good seedling raising mix but the problem is they just sit dormant just not growing. I grow under lights. Last year.. No problems this year no growth. Seeds r less than a year old. HELP.

Tim 2021-09-08
Hi and thanks for your comment. To work out the problem, we need to eliminate a few possibilities. First, check that the temperature and humidity levels within your grow area are suitable for vegetative growth: ideally from 20 to 28ºC with 40-60% RH. Then verify whether your lamps need changing – old bulbs put out significantly less light than new ones, which could be leading to poor growth. If all those factors are as they should be then the most likely culprit is the soil mix itself – the quality can vary from season to season, even with the best brands, so it’s always possible that there could be pests or pathogens in the soil which are preventing the seedlings from making progress. I would recommend trying with a different brand of soil to see if that makes a difference. I hope that helps. Best wishes and good luck!

Fishnass 2021-08-30
I germinated in paper towel until tap root was as long as seed it curled around the seed anyway my question is if I planted in jiffy pod should I put it under light or wait till it pops up to put it in the light .

Tim 2021-09-01
Hi and thanks for your comment & question. The newly germinated seed doesn’t really need a light source while it’s below the soil surface but as soon as it pops out it will need light to prevent it from becoming stretchy, lanky and unhealthy. For this reason, it’s probably best to keep it under a light with a photoperiod of 18 hours light and 6 hours darkness for the day or two that it takes to break the surface. I hope that helps, best wishes!

Master 2021-08-13
You’re incorrect, seeds should be planted pointy end up crown down.

Tim 2021-08-16
Hi Master, thanks for your comment. I honestly don’t believe there’s a correct or incorrect way. In our time, we’ve tried germinating seeds point down, point up and also laying them on their side in the soil, and we’ve come to the conclusion that it makes no difference at all – we certainly didn’t see any real difference in the results of one method compared to another. In nature, cannabis seed dispersal doesn’t rely on the seed landing in the soil in any particular position and it’s managed to spread pretty well! That said, if you like to sow your seeds pointy end down, then that’s great, keep doing it your way if it works for you! Best wishes!

Sean 2021-05-17
I had my seeds in the paper towel for 3 days. The tap-roots appeared(not out just showing a bit) and I planted them in the soil. 3 days have past and I haven’t seen any progress. Is there a reason why this is happening?

Tim 2021-05-17
Hi Sean, thanks for your comment. As long as the soil is neither too wet nor too dry, there shouldn’t be a problem with the seeds. They can take a few days to pop their heads up above the surface once they’re planted, the root needs to work its way downwards and find a solid hold to be able to push the seed head out of the soil. Speaking from personal experience, don’t be tempted to dig around looking for them as you’ll probably do more damage than good. The only times that seeds didn’t come up for me were the times I overwatered them, it’s crucial that they get enough air at this moment and too much water can lead to them rotting quickly. Of course, if they totally dry out then they’re not going to survive either. At this stage, I’d just recommend patience, good luck! Best wishes!

This article has a lot of nonsense in it. From Mandala Seeds: A #1 seed killer is a closed humidity dome/mini-greenhouse. Humidity domes are only required for rooting cuttings. Many growers make the mistake of thinking that they need a high ambient humidity for germination or seedlings. This is an unfortunate myth of cannabis cultivation. The high humidity and lack of fresh ventilation quickly causes fungus in the soil or growing medium and the seeds can rot! Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%. Btw, seed should be planted with the pointed end UP, not down. Tap root ALWAYS goes up no matter how you place the seed. It’s by the nature, goes against the gravity to create a support for itself so it can push the seed out. It you put it with the pointed end down it will have to make double turn loosing the precious energy stored in the seed.

Tim 2021-05-13
Hi, thanks for your contribution. Mandala Seeds give some helpful advice but they don’t have a monopoly on germination methods! In my 20 years germinating seeds I’ve tried all different methods and I’ve found good and bad in all of them. except for the methods using moist paper towels, I refuse to use it these days – I found that’s a great way to get mold problems and a really bad start to the plant’s life! That definitely is far too much humidity. as for ambient humidity, we don’t specify anything in this post. What we do say is that the medium in which the seeds are germinating should be at about 70% humidity for the best results. There’s nothing wrong with using a humidity dome or mini greenhouse, as long as you know when to start ventilating. of course if it’s kept sealed all the time then problems are bound to arise! These days I start all mine in a glass of water with a few drops of H202 and then once the seeds open (usually 24 hours) they get transferred to the substrate. As for the point down/point up debate, I think I’ll need to do a side-by-side comparison to settle this in my own mind. I’ve always planted them point downwards or on their side and I’ve yet to see any weird stuff like roots popping out of the surface, or doing a loop-the-loop before the seedling breaks the surface. But it’s clear that the debate needs to be settled so I’ll do an experiment and I’ll be happy to be proved wrong! EDIT: I’ve since germinated over 100 seeds as a test, 1/3 of them went in the soil with the point downwards, 1/3 sideways, and 1/3 with the point upwards. Most of the seedlings broke the surface at around the same time but it’s clear to see that the ones that I’m still waiting for are mostly those that went in with the point upwards. The next step has to be a test in a terrarium so I can actually see what’s going on but I’m almost ready to call complete BS on this “point upwards” theory, FWIW. Thanks again for your comment, all the best!

How to Germinate Cannabis Seeds

Germination relates to the process of a new plant growing from a seed. It is the first step when adding to your cannabis garden. You can purchase the requisite seeds from a variety of sources. On the downside, it means that cannabis seeds vary enormously in quality. We recommend looking at reputable online seed banks to get your supply. However, please note that there are legal issues to contend with if you buy seeds. This is especially the case if you decide to buy them from a source outside the United States.

When buying seeds, opt for mature options with a dark brown appearance and a firm feel. Once you have them in your possession, make plenty of space for them to grow and thrive. Learning how to germinate weed seeds correctly is crucial to enjoying years of healthy plants and fruitful harvests. In this guide, we outline the ideal germination conditions and show you five different methods.

Ultimate Guide to Cannabis Seed Germination

In theory, germinating cannabis seeds is a simple affair. They only need three things: Air, water, and heat. The famed ‘paper towel’ method is incredibly easy as long as you follow the steps outlined below. Here is a quick overview of the best germination practices before we show you the various methods.

Water

Be careful not to over-soak your seeds. Hard seeds should be soaked for a maximum of 32 hours, although 24 hours is usually enough. Soaking too long can damage them. Marijuana seeds begin to sprout when they receive the twin signals of water and heat.

Once the right conditions occur, the taproot starts burrowing through the shell of the seed.

If the root breaks through the shell and there is no water, the seedling will die. Keep the roots moist once the seed sprouts, and make sure there is ample moisture at all times.

This is arguably the trickiest aspect of germination. You have to strike a balance between ‘warm’ and ‘hot.’ Spring temperatures are ideal in a ‘normal’ year. While cannabis seeds can germinate in colder weather, the process takes longer. Seedlings also germinate faster when there is plenty of humidity in the air. If you are concerned about low temperatures, invest in incandescent bulbs, and place them over the seed area.

First and foremost, seeds perform at their best when they are left alone! When you check them for the taproot, handle with care! Try to avoid touching the white taproot because it can easily break off.

Planting

You don’t have to plant germinated seeds too deep in the soil, or whatever growing medium you choose. 0.5” – 1” below the surface is plenty. Point the white root downwards into the earth to ensure the seedling is ideally oriented.

Are Your Seeds Good or Bad?

Always opt for dark cannabis seeds as they are the most likely to germinate when kept in the right conditions. White or pale-green seeds have little or no chance of growing.

You may have heard the age-old advice on checking for viable seeds. Apparently, if you can crush seeds between your fingers, they are ‘bad.’ First of all, they won’t be good seeds because you have destroyed them! Secondly, experienced growers know that even flimsy seeds can germinate when exposed to the right conditions.

How to Germinate Marijuana Seeds – 5 Methods

1 – The Paper Towel Method

This is the easiest method and requires cannabis seeds, paper towels, and two clean plates. A word of advice: Choose cheap paper towels because they are non-porous. As a result, you can lay seeds and roots on the surface and not worry about them getting stuck. If you use high-quality paper towels, the roots will grow into them!

It is a simple method, but also a risky one. You could damage the taproot while moving the sprouted seeds, or else the paper could dry out and kill the seeds. In any case, here is the process:

  1. Use up to four sheets of paper towel and soak them in distilled water. While you must soak the sheet, make sure there is no water dripping off.
  2. Place two of the paper sheets on one of the plates. Lay the seeds down at least 1” away from one another. Cover with the other two layers of paper towel.
  3. Cover the seeds with the second plate to lock in moisture. You have created a low-cost dome! Make sure you check the seeds often to see if they have sprouted.
  4. Keep the seeds in a room where the temperature is between 70- and 90-degrees Fahrenheit.
  5. Now you must wait! Seeds typically sprout within 1-4 days, although older seeds often take up to a week.
  6. When checking the seeds, make sure the sheets are saturated. If they are drying out, add more water.

You will know that germination has occurred because the seed will split, and a little root appears. Make sure you don’t touch the taproot when it sprouts or during the transplantation process.

EDITOR’S CHOICE – Homegrown CannabisCo

Homegrown CannabisCo are the masters when it comes to seeds. Offering a massive variety of cannabis seeds that are well categorized, not only does this company create a resource for superb quality options including feminized seeds, it also provides extensive growing information for those looking for some support along their journey.

2 – Direct Planting

In nature, a marijuana seed will germinate in the soil and emerge with its taproot growing into the earth. Therefore, you can plant cannabis seeds straight into your growing medium of choice. The main benefit here is that you don’t have to worry about ‘shocking’ the seedling while transporting it.

Your seedling should instantly adjust to the new environment and grow. When using this method, dig a hole 0.5” – 1” deep in soil that is moist but not saturated. Keep things warm with a heating pad or lighting.

3 – Starter Cubes and Seedling Plugs

This has been championed as the easiest germination method. It is effectively a foolproof method. All you have to do is place the seed into the cube/plug and add water. Assuming you put the seeds in a room with the right temperature, germination should occur automatically within a few days. There is a pre-made hole for the seeds, so it is a ‘set it and forget it’ method.

The main downside with this germination method is that such plugs are generally available in packs of 50. Waste is inevitable if you only plan on planting a few cannabis seeds. The plugs dry out in a week or so and become unusable.

You can also use Rockwool cubes as they are cheap and easy to find. However, they are a terrible burden on the environment and bad for your health. Rockwool also has a high pH (which means you must rinse the cubes first) and offers a low cloning and germination success rate.

4 – Overnight Soaking

This is as simple as option #3. It involves nothing more than placing the seeds in a glass of lukewarm water overnight. It is a good idea if you’re using old and hard seeds. The soaking process can breathe new life into them. When you place the seeds in water, they float for a few hours before sinking to the bottom.

The soaking process can breathe new life into old seeds.

If you use a transparent container such as glass, you get to see the white taproot break out! You shouldn’t leave seeds soaking in water for more than 32 hours. Otherwise, seeds that haven’t sprouted yet will drown. If the seeds haven’t germinated by the 32-hour mark, put them in a warm and moist place to complete the process. You should probably use the paper towel method at this point.

5 – A Germination Station

You can purchase a readymade version online. Alternatively, attempt a DIY station by placing a plastic dome over a plate that you then add to a heating pad. Professionally made stations are relatively inexpensive and work rather well. You can buy one for under $40, and their plastic tops ensure better humidity control. With top brands, all you have to do is choose your growing media and plugs to start growing.

Transplanting Germinated Cannabis Seeds

There is no room for a delay once your cannabis seeds have begun to sprout. Now is the time to transfer the seed to its growing medium. Most growers prefer to use small pots, to begin with. Make sure you fill enough pots with loose potting soil and use a pencil to poke a hole around 0.25” deep. Remember, you could break the taproot very easily. Transfer it using tweezers and drop the seed into the hole with the root facing down. Finally, cover it with a thin layer of soil.

For the first few days, use a spray bottle to water the seeds, because adding too much water can drown them. It is worth investing in a pH meter to test the soil regularly and make sure it has enough moisture. If all goes well, the seed should sprout from the earth within a week. If it hasn’t sprouted within ten days, it will probably die.

Turn on your grow light once you have planted the seeds. The heat improves germination rates and speeds up the process of the seedlings opening their first set of leaves. These leaves will remain yellow until exposed to a sufficient level of light in any case. When you plant multiple seeds, you will find that they grow at different rates.

Inevitably, some will fail, while others will flourish. You will have seeds that pop fast and proliferate. Don’t be disappointed if you have a few failures because that’s part and parcel of the growing process. Even when you get everything right, you will inevitably lose a few seeds, and it won’t be your fault!
