Autoflowering Seeds

Autoflowering plants automatically move from vegetative to flowering without anyone changing the lighting. This makes them perfect for beginner collectors, and why so many in the Seedsman community collect autoflowering cannabis seeds.

Additionally, they’re more compact and easier to care for, can better handle pests, and are ready to harvest sooner in legal markets.

Autoflowering seeds are a Seedsman speciality; we were the first to sell autoflowering cannabis seeds to the public. Check out our conversation with The Joint Doctor, the first cultivator of autoflower genetics here .

How to Grow Autoflowers

#1 Getting started before you get started

It’s tempting to browse an autoflower product page and get excited by the prospect of your own home-grown buds in just a few weeks. But, because they don’t take long to grow once potted – you must plan your growing process beforehand.

What growth medium are you using? If you’re growing outdoors, is the climate correct this time of year? If you’re growing indoors, have you sorted out your lights and ventilation?

Growing different plants gives you wiggle room to adjust how you raise them. Autoflower’s speed means you need to have all your ducks in a row before you even begin germinating.

#2 The right pot for pot

You’ve designated your space outside, or you’ve plugged your lights indoors, and you’re ready to go. Autoflowering cannabis doesn’t like being repotted due to its short growth cycle (if you’re going to repot, rather do it sooner than later), once your seeds are planted, ideally, then that’s where they should stay. You need to ensure your pots are the right size for a fully grown plant.

You shouldn’t need overtly large pots as autoflowers are generally more petite; nevertheless, the pot needs to have enough room for the roots to grow.

They also need to drain well, so perhaps breathable containers like fabric pots are your best bet. Otherwise, plastic pots with plenty of drainage holes will work just fine if that’s your only option.

3 Getting your nutrients right

Recently, the Godfather of autoflower strains himself, The Joint Doctor, joined Seedsman on a live stream to share his advice on growing autoflowers; he said – “One of the best ways to grow autoflowers is low intervention, don’t overthink them.

Nutrients are important, but most autoflowers don’t require too many nutrients because you’re adding things to improve a plant that’s already genetically designed to grow as is. Just use your common sense. If the plant is growing fine and looks good, then adding nutrients is just trying to improve something that’s already working well. If they need ‘em, then add ‘em, but don’t add nutrients for the sake of it.

Anything that you do wrong will stunt the plant, so, be gentle with it – whether that’s gentle with planting or with nutrients. Be gentle”.

So, there you have it. Autoflower roots are less expansive than photoperiods, so if you’re following a nutrient chart, ensure you’re considering the size of your plant and adjust accordingly.

The best practice with autoflower nutrients is not adding too many and allowing the plant to grow as organically as possible, if possible. If you’re growing indoors where you’re controlling the environment, if you get your lighting, ventilation and humidity right then, nutrients shouldn’t be overthought but still, need proper consideration.

#4 Let there be light

Autoflowers are tough and adaptable, but if you light them right, you’re making their lives that much easier. Autoflowers work best with an 18/6 light ratio. Some growers insist on a 24-hour life cycle from the beginning until harvest. We’d say give them a break as sometimes you can get too much of a good thing.

If you’re growing outdoors in the summer, you may be worried about only getting between 10 and 12 hours of sunshine, but the sun is far more powerful than any artificial light, so don’t stress too much.

Indoors try and use full-spectrum LEDS as the more lumens on offer, the greater the yield. That being said, autoflowers do prefer HPS and LEDs over CFLs or fluorescents.

#5 Go go H20

Yes, autoflowers are resilient and more forgiving, but get your watering wrong, and you’ve got no chance. Not enough water means a dead plant, too much water leads to a rotting one.

So, how do you get this right?

Well, try and stick to a regular watering schedule. But use your common sense. There isn’t one schedule that fits every grow. There are too many variables like soil composition, humidity, plant size, age and more to nail down a single watering guide.

When you first plant your germinated seed, try and ensure your soil is moistly dampened before adding the seed. Many first time-growers make the mistake of watering the soil immediately, which can drown the seed. If needs be, give it a light sprinkle.

Water, like lighting and nutrition, comes down to observation. Adjust accordingly.

#6 Consider your pH

Inside or outside, soil or hydroponic, pH needs to be considered every step of the way.

For a hydroponic grow, your pH balance should sit between 5.5 and 6.5. In the soil, anywhere between 6.0 and 7.0 is fine.

pH falling below 5.5 means nutrients like magnesium and calcium aren’t absorbed; the same goes for anything higher than 7.0. An incorrect pH in either your water or your soil can and will ruin a yield.

So, ensure you invest in a suitable pH measuring product like a pH meter handy to keep an eye on your harvest.

#7 Don’t forget your training

Due to the reduced seed–harvest period, you need to train your plant to encourage a better yield as soon as possible. These need to be LST’s (o, Low-Stress Techniques) as the plant will still be quite fragile.

This means ensuring all bud sites get equal light and possibly using string and toothpicks to ensure they’re propped up and balanced.

Some say you should top your autoflower as soon as nodes appear to encourage a more extensive canopy as well, but, as the Joint Doctor said, sometimes less is more.

Your aim should be to ensure your stems are supported and equally lit. How you do that is up to you!

#8 Not too hot, not too cold

Despite their resilient nature, if you’re constantly fluctuating the temperature in which your plants are growing, then you’re not going to have any success.

Growing them outdoors means you’re at the mercy of the elements, so ideally, you’d have them planted in the summer, where most of the time, it’s warm. Even still, if the temperatures are soaring, you might need to consider shading your plants to reduce the heat on them.

The perfect temperature for an ideal autoflower harvest is debatable, but most agree that anywhere between 67 and 77 degrees Fahrenheit (20-25 degrees Celsius) is excellent.

Also, your plants need fresh air circulation (as does any growing plant) to help reduce the chance of moulding and ensure proper moisture.

Sit down where your plants are growing for a few minutes. Are you warm enough? Too warm? Is it too breezy? Do you need some shade? If you’re feeling any adverse effects, then so are your Autoflowers.

#9 Harvest patiently

When your plant begins to flower, each bud will bloom differently and thus not ready to harvest all at the same time. The buds at the top usually mature faster than those lower done, so start with those.

Leave the rest for another day, two or three, and then they can be harvested. This ensures a good yield and, if done correctly, can give you a result all year round if they’re growing in the right conditions (indoors, usually).

#10 Have fun with it

If this is your first time growing autoflowers, then chances are it’s not going to go perfectly. The best way to learn is to make mistakes and ensure you don’t repeat them. Autoflower cannabis, despite its incredible genetics, is still just a plant.

And, like any plant, on top of light, food and water – they need love and attention. Your yield matches your efforts. Put the work in, share the love, and your plant will grow big and strong with large, sticky buds.

What are Autoflower Seeds?

Autoflower seeds produce a very different cannabis plant than photoperiod seeds. Photoperiod cannabis plants will only flower if they receive certain hours of light.

Plants grown with auto flower seeds do not rely on a light schedule. They will usually start flowering within 3 – 4 weeks of germination.

Why Grow With Autoflowering Weed Seeds?

Compared to regular, feminized and fast version seeds, autoflowering cannabis seeds have many advantages.

  • Beginner-friendly. Autoflower plants won’t tolerate much stress or injury but they grow fast enough to lower the chances of anything catastrophic.
  • Small and discreet. Autoflowering plants rarely grow taller than 3 feet and can easily fit inside grow cabinets and other tight spaces. A more discreet option for private cannabis growers.
  • Lower THC content. Autoflower cannabis plants have lower average THC levels. Don’t worry! This is a generality, scroll down to see ourtop high-THC autoflowering strains. The gentler psychoactive effects of autos suit those with low THC tolerance.
  • Autoflowering plants CAN produce high yields. Auto-flowering plants don’t yield as much per-plant as your average photoperiod cannabis plant. The advantage lies in the speed. An auto will produce multiple yearly harvests, often outperforming photoperiod plants over a season.

How much yield can you get from auto flower seeds?

Your autoflower yields depend on the timing of your harvest and the autoflowering genetics of your plant. Indica heavy auto flowers tend to produce smaller yields than sativa heavy autos.

Sativa-dominant autos are also known as super autos. Traditionally, super-autos can deliver 2 to 4 times bigger yields than standard autoflower plants.

The cannabis research of our breeders and those of other weed seed banks moves at breakneck speed. When trying to gauge how much yield you will get from your auto you need to think long term.

Autoflower seeds deliver multiple yearly harvests

A case in point: Homegrown Cannabis Co. stocks two versions of Amnesia Kush. You can buy Amnesia Kush Feminized marijuana seeds which produce up to 28 ounces per plant. Or you can choose Amnesia Kush Autoflower marijuana seeds which yield anything up to 12 ounces per plant.

With the photoperiod Amnesia Kush your top yearly yield is 28 ounces. A good yield, no question. But with three harvests of the auto version in the same year your overall yield could be a whopping 36 ounces.

Multiple harvests, multiple throws of the dice

With three cannabis grows in the same season you can improve your technique, adjust the nutes and perfect the environment. With a single yearly harvest all of your eggs will be in one basket . As will any mistakes.

How To Grow Autoflowering Seeds?

There is no need to think about the light schedule (photoperiod) when growing autoflower strains. One schedule and one lamp is enough for the entire growth cycle.

The most popular light schedule is 18/6 (18 hours light and 6 hours dark). You can push this to 24 hours without harming the plant or productivity although the electricity bill might hurt your wallet!

There are varying schools of thought when it comes to growing autoflowering weed seeds. Some auto cannabis growers think the plants benefit from the period of rest with an 18/6. Other growers give them maximum light for as long as possible.

Pro tip: always do what works for you.

Auto strains are beginner-friendly. You still need to follow the basics of cannabis cultivation. These pointers should help you get the best from your autoflower harvest. We will expand these autoflower grow tips later in the article.

  • Growing environment: Autos thrive in warm and dry conditions with temperatures ranging from 75 to 86°F. Relative humidity levels are best kept at 40 to 50% to prevent mold and mildew.
  • Stress: Autos struggle to recover from stress or injury. When wounded, the plant’s energy is focused on repair rather than growth. This is not good news for yields. Avoid high-stress training (HST) methods. Use low-stress training (LST) sparingly and very, very carefully.
  • Autoflower nutrients: Autos are small plants that spend little time in the vegetative growth phase. They don’t need a lot of nutrients. Feed them lightly and go easy on the nitrogen.
  • Harvest gradually: Harvest the buds sequentially by snipping the top colas first. Let the lower buds fully develop before harvesting next.

What soil should I use for autoflowering seeds?

Autoflowers prefer a lighter, more aerated soil than you would use to grow feminized photoperiod cannabis plants. Perlite is a fantastic way to improve drainage and airflow.

What is the optimal temperature and humidity to grow autoflowers?

Your grow room needs to be kept around 21°C (70°F) for the best results. Anything much higher or lower can lead to grow problems and plant stress.

Your autoflowers need relative humidity (RH) levels of 40–50%. This can be a little higher for young autoflowering plants. Once in flower keep the RH levels to 40%. This will reduce the risk of mold, mildew and stress.

What kind of nutrients do autoflowers need?

Buying autoflower weed seeds lowers the cost of your nutrients. Auto plants are smaller and less demanding than their feminized photoperiod cousins.

When using commercial cannabis nutrients give your autos around a half or a quarter of the recommended dose. Pre-fertilised commercial potting mixes are ideal. You won’t need to feed your autoflowering plant until the third or fourth week of growth.

What kind of water is best for autoflowers?

Autoflower seeds have different requirements to photoperiod feminized cannabis seeds. Auto flower plants are smaller and have a more compact root system. They need less water than larger feminized photoperiod plants.

The key is not to overwater. Allow the soil to almost dry between waterings. Cycling wet to dry is a good system for both autoflowering AND photoperiod plants.

When growing autoflowers in soil the optimum pH level is 6.0 – 7.0. The pH level can be optimized for autoflowers by using natural products such as pH up and pH down.

Can you train Autoflowers?

Photoperiod cannabis plants love nothing more than High Stress Training (HST). Growers can employ plant training techniques such as super cropping, FIM, topping and defoliation to massively boost yields.

This is not a good idea for feminized autoflower plants. HST involves damaging the plant to make it grow back stronger. Autos do not have the time to grow back.

The only training that works with auto flowers is low-stress (LST). Bending branches to expose more bud sites is fine. Do not break the branches and do not cut or pinch any part of the auto cannabis plant.

What is the best way to germinate Autoflower seeds?

Germinating auto flower seeds follows exactly the same process as germinating feminized or regular cannabis seeds. Learn how to germinate autoflower seeds by watching our germination guide.

Before planting your autoflowering cannabis seeds, you need to germinate them. The best germination method for autos is the same as for photos. Please see our full germination guide above.

When your auto flowering marijuana seeds have germinated it’s time to prepare your pots. Red solo cups are a great example of a small starter pot. Try to avoid using jiffy pellets as the roots will need space to grow.

The first job is to fill the pots with your chosen soil. Leave an inch gap from the top to stop soil spilling out and water the soil in preparation. This is the only time you’ll water until the sapling appears. Watering while the taproot is still getting established can cause problems. It can displace the germinated seed.

Make a small indent in the soil with the tip of your finger, around a centimetre deep. As central as possible. Lower the seed into the hole with the taproot facing down and loosely cover the hole with soil. Leave it under your grow lamp for a few days. Soon it will pop up through the soil and spread its first leaves. After letting the sapling develop a little you need to transplant it to the final pot.

Tip: don’t let it establish itself too much, 6 days is the longest it should stay before transplant.

When you transplant autoflowers to their permanent home you’ll need to choose your pot size relative to flowering time. A two month (8 week) flowering time will need a 1.5 gallon pot. A three month (12 week) flowering period will need a larger, 3 gallon pot.

Again, fill the flowerpots with soil to within an inch or two from the top and water. Compact it a little if you want but not too much. Your plants need to expand their root ball and take oxygen and water from the soil.

The transplant process is the same for photoperiod seeds. Make a hole in the top big enough to fit both the roots and part of the trunk. When planted, you want 2 inches from the top of the soil to the first set of leaves. Water again once your transplant is complete but only around the edges of the pot.

Step by step guide to growing Autoflower seeds indoors

Step 1: Choose where to grow your autos

How do you grow autoflower seeds indoors? It starts with deciding where to grow autoflower seeds indoors . Good options are tents, grow boxes, closets, maybe a spot by the window. Make sure you can grow cannabis legally and ensure the window spot gets lots and lots of sun.

Step 2: Buy autoflowering seeds from Homegrown

Healthy plants need strong, reliable genetics. This is guaranteed at Homegrown and we have the best autoflowering seeds for sale anywhere online.

Choose auto seeds according to flowering time and whether you prefer more indica or more sativa in your plants.

Step 3: Decide on pots and growing medium for indoors

Autos are fast cannabis plants. They will veg for around 2 to 4 weeks and then flip into flower. This leaves no time for any more than one transplant .

Your final pot should be no bigger than 3 gallons when growing autoflowers indoors . Your grow medium should be well-aerated and lightly fertilized. A good soil mix or coconut is ideal.

Step 4: Choose your grow lamp

Cannabis growers have plenty of choice when it comes to lights. Metal Halides (MH) and High Pressure Sodiums (HPS) were the traditional market-leaders. LEDs are now the number one choice of cannabis lamp while CFLs are still a popular choice for the early stages. Grow lamps play a MAJOR role when growing any kind of cannabis indoors.

Planting feminized autoflowering seeds under LED lighting is extremely popular. LEDs are cheap to run. A big plus for growers who like to give their autoflowers 24 hours of continuous light.

They also run cool so you can put them closer to your plants. If you’re growing autos from seed the chances are you won’t have much space. Maybe LEDs are the popular choice for you, too?

HPS and MH lamps are also perfect for autoflowering marijuana seeds. They are hotter, more expensive to run and require more room than LEDs. But they’ll give your auto flowering seeds a brilliant chance of success.

You can grow autoflower indoors without lights, too. A sunny spot on a windowsill or in a conservatory will suffice. The sunnier your climate, the better your yields.

Step 5: Germinate and plant your autoflowering seeds

Growing autos in a pot. Pots are easy to move around. This is useful in areas vulnerable to flash floods and high winds. You can also move pots to the sunniest areas, depending on the time of day. One downside to pots is space. Roots might not get the room they need to fully develop. This could limit the overall growth of the plant.

Growing autos in the ground. If your aim is to grow a big autoflower plant then plant in the open ground. Your roots will be free to expand and the plant will grow as high as its genetics allow. Growing auto-flowers outdoors will better equip them to deal with a little wind or rain.

How To Get The Biggest Yields With Autoflowering Cannabis

This answer recaps what has already been discussed, but with a few extra autoflowering tips and tricks .

  • Start autoflower plants in their final containers : you can sow your autoflowering feminized seeds directly into their final home. This will promote the early growth of a healthy root zone.
  • Use bigger pots : for an experienced grower anything up to a five gallon pot is acceptable. The bigger the pot, the bigger the potential for growth.
  • Use better pots : Healthy root systems mean healthier plants . Fabric pots will help prevent your cannabis plant becomingroot bound which is better for their overall health and development. Fabric cannabis pots also prevent overwatering as they have incredibly good drainage.
  • Optimize your grow medium : Adding perlite or coco coir helps aerate the soil, improving water and nutrient uptake.
  • Use root stimulants : Beneficial fungi encourage nutrient uptake and enrich the root zone.
  • Support your auto-flower plants : Keep your autos upright and healthy by using stakes or trellis.
  • Light, light and more light : We have touched on this before. Many growers limit the light cycle to 18/6 but some plants are comfortable with 24 hours of light . Adapt to the limitations of your plant.
  • Reverse osmosis water : Chlorine and fluorine can have a negative effect on your autoflowering plants. Reverse-osmosis water gives you control over mineral levels .
  • Think about the nutes : Autoflowering feminized seeds do not need many nutrients. They love enzymes, beneficial fungi and vitamin B, but not much else when it comes to base nutrients. More than any other type of cannabis plant, less is more when it comes to planning a feeding schedule.
  • Dial in your pH : Don’t be afraid to use off-the-shelf products to adjust the pH. The optimum zone is 6.0 to 7.0.
  • Adjust climate for growth stage : Too many cannabis growers depend on the amazing resilience of autoflowering pot plants . Take the time to adjust humidity levels with the stage of growth.
  • CO₂is your friend : Well, it’s more of a friend to your auto plants . When growing marijuana autoflower seeds indoors a healthy boost of CO₂ has been proven to boost growth . Make sure you mimic nature and only add CO₂ during ‘daylight’ hours.
  • Train your plants (but don’t stress them) : There is a big difference between low and high stress training . The former is great for feminized autoflower seeds , the latter is not.
  • Bending and tying stems to expose more buds to light is a non-invasive way to increase overall yield . This is about the limit of training for auto flowers.
  • Use Sea of Green : Autoflowering weed plants LOVE a Sea of Green (SOG) set-up. Just like autoflowering cannabis, it’s a system that maximizes yields with minimal space .
  • Progressive harvesting: Untrained plants will nearly always have more developed buds at the top of the plant. This is especially true with autoflowering cannabis plants. A good way to overcome this phenomenon is to use progressive harvesting. Harvest the highest buds when they are ready and let the lower buds enjoy longer periods under the lights. This could translate to a couple of weeks extra in the grow room but the higher yields will be worth it.

Keep records : Any master cannabis growe r will tell you to make notes and document everything relevant to your grow. This will help you problem-solve and prevent issues . Taking notes will seriously improve your skills.
