Everything you need to know about autoflowering cannabis seeds germination.

Do you want to know the details about auto flowering cannabis seeds germination times? You should understand that autoflowering cannabis seeds are like regular seeds and exclusively feminized seeds, so they grow in the same way.

The differences lie solely in the fact that the growth of self-flowering cannabis plants, and their flowering, are much faster than other types, and that the flowers grow and ripen spontaneously regardless of the amount of light/darkness received by the plant.

The germination process is the same for feminized or regular plants. Growers only treat them a different way after the shoots are starting to grow.

So how long does it take for auto flower seeds to grow?

Temperatures and germination time of self-flowering seeds

As with other types of marijuana seeds, self-flowering feminized seeds begin to germinate after 2 to 4 days, from the time the grower plants them. For the germination process to be successful, it is necessary to keep the seeds in the dark and to maintain the right temperature in the growing environment.

In general, cannabis seeds grow at different temperatures, but the optimum temperature is about 27 degrees Celsius for air, and about 25 degrees Celsius for soil, cotton and/or water. Growers rarely worry about minimal variations in temperature, also because self-flowering plants adapt well to more or less all weather conditions.

In any case, different methods can be adapted to lower or increase the temperature. For example, LED lamps can be used for the first phase of seedling development (including germination). If the environment is excessively hot, there are fans/air conditioners if it is too hot in the room or greenhouse.

Not only the temperature, but the water on which the seeds feed is also essential for high quality and fast germination.

Germination of self-flowering seeds in water

Well, yes. One of the most common methods used by cannabis growers is the germination of cannabis seeds in water. It is a straightforward method, and it is difficult to find problems with seed germination after following it.

Here are the main steps of this procedure:

    are immersed in a glass or container filled with water (strictly sterilized to prevent bacterial proliferation). The water temperature must remain about 20-25oC.
  • At this point, the producers grow the seeds below the surface and then let them float. The seeds should flow after a time ranging from 2 to 4 hours. If during this time, they do not fall to the bottom of the container, the producer pushes them with his fingers to do so.
  • The seeds then develop small roots in about 1 to 2 days. At this point, they are positioned between two layers of cotton (you can use cotton discs, much less porous than tampons), or previously moistened paper towels.
  • After a few days, the rootlet of each marijuana seed should be 2 or 3 centimetres.
  • Growers can finally plant cannabis seeds in the soil.

Cannabis seeds germination in water: how to move from cotton to the soil?

After germination in water, and once the phase is completed in cotton; growers can plant weed seeds in pots or soil. They can also use other growing methods such as aeroponics and hydroponics, which do not use land.

You make a hole in the ground with a finger, take the seed and place it in the soil with its rootlet down. You cover the marijuana seed with the earth and wet it carefully, without “drowning” the seed.

Growers carefully check the soil to make sure it is moist enough. When seedlings germinate from the ground and begin to grow, this means that it is in the vegetative phase, during which the optimal hours of light are 18 hours (some growers, however, subject the cannabis plants to 24 hours of sun per day instead of an 18/6 cycle).

Problems germination of self-flowering seeds? Here are the possible causes.

Several stressors could prevent autoflowering (but also feminized or regular) cannabis seeds from sprouting.

Here are the main reasons:

  • Cannabis seeds are not perfectly ripe. Marijuana seeds should be mature for germination. The ripening is visible thanks to the colour: usually, the immature seeds are green, the ones ready to be planted are brown or dark grey.
  • Inappropriate germination temperatures: Perfect temperatures range from 20 to 25 degrees Celsius and must be constant.
  • Environment little or too wet. An excessively dry germination environment does not promote the birth of rootlets and seedlings, while an environment that is too wet (except for the first 24/48 hours in water) causes the seeds to rot.

Now you know all about the germination of autoflowering hemp seeds, but these procedures can also be applied to feminized and regular seeds.

However, you should remember that in the UK, you cannot germinate marijuana seeds. You can only harvest them if you live in a country where personal use and cultivation is allowed … then, in that case, you have the green light!

Planting Autoflowering Cannabis Seeds

Planting autoflowering cannabis seeds is a relatively easy process, but to get the most out of your plants you need to follow a series of steps that are completely different from those that seasonal seeds have. An autoflowering cannabis seed needs a bit more care than normal seeds. You need to speed up the growth as much as possible so you don’t get teeny plants with no more than 5 blunts on them. We’re going to give you a series of things you’ll need to do in order to get the most out of your plants.

Germinating Autoflowering Cannabis Seeds:

The first thing that you’ll need to do is germinate the seed properly, using the paper towel method that we’ve talked about here before.

Once your seeds have germinated or opened, however you prefer to call it, you’ll need to prepare some small Teku 7×7 pots with soil, don’t use jiffy pellets or anything like that as the roots need plenty of space to grow.

Fill the pots with soil first and then water them; once the plant breaches the top of the soil you mustn’t wet it again. If you water it before the seed has come out then it will probably move up towards the surface which can cause a whole list of other issues. The best thing to do is to water first and then wait to water it again until the sapling grows a bit.

Bury the seed about half a cm to 1cm down into the soil, making a hole with a pen or a toothpick and putting the seed inside with the little root facing downwards. Cover it with a bit of soil without compacting it too much and leave it there until the plant begins to grow above the soil. What we usually do is leave it for 24h with light during this process until you transplant the seed to its main flowerpot. If you don’t have grow lights then use the most powerful one you can so that it doesn’t get too cold in the pot.

Up until this point the process has been exactly the same for seasonal seeds, but that’s about to change. You’ll need to wait for the plant to break the surface and have that little growth spurt that cannabis plants tend to get when they’re looking for light. This can take 4 or 5 days, and you’ll need to keep a close eye on them so you don’t leave them for too long. Make sure that the plant doesn’t begin to develop in that flowerpot, the maximum time you should leave the plant in it is 6 days.

Now is when you’ll need to transplant your autoflowering plants to their permanent home. Autoflowering strains that take two months prefer pots that are about 7L, whereas those that take three months much prefer pots that are 11L, no bigger.

Fill the flowerpots to the top with soil, nice and compact so that when you water the water doesn’t go all the way to the bottom, although make sure you don’t compact it too much as the plants need a good oxygen/water ratio to breath and grow; with no oxygen the roots won’t be healthy at all and you’ll end up with a dwarfed plant. You’ll need to keep the light at 20h until the end, or make sure it’s in a spot where it can get the maximum amount of sunlight hours.

Once those pots are full of soil, you’ll need to make a hole to stick your small plant in. Make it deep, as you’ll need to bury part of the trunk as well, to the point where the bottom of the trunk is just 5cm long from the soil to where the first leaves are. Then, water the edges of the pot little by little so the soil gets properly humid.

The reason you need to bury part of the trunk is because even more roots can come out of that small piece of stem, and it also gives the plant stability and strength so that it doesn’t bend and break and it can spend more energy on growing branches and foliage. The more roots it grows the more the plant will grow, which is how you can easily speed up the growing process. Once you’ve buried it, water the plant with about a liter of water mixed with a low concentration of growth fertilizer; some substrates absorb water easier than others, so it might be trial and error in your case and you’ll need to adapt the amount of water to how absorbent your soil is.

I use a liter of water with Canna Terra Professional, and no excess water comes out of the holes in the flowerpot which means it’s adequately watered. You can read all about substrates here.

From this day onwards you’re going to need to check and see if the soil is dry; until it is completely dry you shouldn’t have to water it again, and this should take about 7 days. The best way to check if the soil is dry is by lifting up the pot; if it’s still pretty heavy then it still has water in it.

The next step is watering with growth fertilizers once it’s dry after that first watering. You should be at around day 13 or 14 and you’ll have noticed a bit of growth in the last couple of days. For watering, you should make your mix in a bottle with just one glass of water per pot at this stage. The next day check and see if the pots are heavy; if they’re dry then give them another glass of water but if they’re not don’t water them again until the next day. If the soil is extremely dry the next day then you’ll need to give it two glasses of water. Up the dosage as time goes by little by little and this process of dryness and water will make the plant grow a nice root system, as well as an amazing production.

Before you realize it, it will be day 25 and your plant should be beginning to flower. It no longer looks like the plants you had before, does it? You haven’t changed the seeds, just the method. Now all you have to do is follow the typical flowering steps that every seed needs; a flowering stimulant to begin with, a flowering base, a fattening products once the buds have formed, and end it all by washing out the roots. Flowers take about 20 days to properly form and the fattening period lasts about 2 weeks rather than four weeks for a seasonal seed; once you see the flowers forming properly then you need to use the fattening product.

We’re sure that if you follow these steps you’ll be extremely happy with the results that your autoflowering plants will give you compared to other grows you’ve tried. You might even see some of the mistakes that you made corrected in this article. Many people will probably say to never transplant autoflowering plants, but those people won’t get specimens as big as you will if you follow this guide!
