Autoflowering seeds germination time.
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.
PSYCHO XXL AUTOMIX
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!

How Long Cannabis Seeds Germinate?
If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.
So now you know how long cannabis seeds germinate, what will happen after?
After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.

Why Didn’t my Seeds Germinate?
Why didn’t my seeds germinate? This is a question often asked by novice and experienced growers alike. Some people think that it’s because they bought old seeds or badly made seeds, but it’s generally because the germination process isn’t done properly. Cannabis seeds have a 99% germination chance, even after being in a box for up to 5 years.
Cannabis seeds are life matter, and if germination isn’t done correctly then the seeds are worthless. Cannabis plants are generally quite sturdy and they grow quite fast, but they’re extremely fragile before they begin their growth spurt. You need to germinate in humid places with a decent temperature, and make sure that the seeds have enough humidity for the 2-10 days it can take for them to germinate. Just because it hasn’t shown any roots in four days doesn’t mean that the seed isn’t going to open, you just have to wait and have some patience.
One of the most common errors is just leaving them in some damp kitchen paper on a plate, as they’ll dry up before they can root. You need to make sure that the paper isn’t dry, if it’s dry you’ll need to give them a bit more water, some people give them too much water in case they dry out etc. These practices are what cause seeds to dry out or to drown in too much water; it’s not the seed’s fault, but generally the grower’s.
Another big mistake is germinating in a glass of water. The issue with this method is many people don’t take into account the water temperature. If the water’s too cold then the seeds will sit there for days until they eventually rot due to the low temperature in the water. This method’s okay for warm summer months when there’s a decent temperature and the water doesn’t get too cold. This still isn’t the seed’s fault.
One of the biggest mistakes is germinating straight in a jiffy or soil. The issue here is that the seeds will most likely take much more than 48h to germinate, and by then the upper layers of soil will have dried out, and if it doesn’t die off due to that then it will probably die if you try and water it to keep humidity up; in these cases, the seed tends to come to the surface or they can sink even further into the soil. Once again, this is the grower’s fault.
The only way to be sure that your plants are going to get a chance to grow is to germinate them before putting them in the desired medium. The only way to make sure that they germinate is to make sure that the temperature never goes below 20º and that the paper doesn’t dry. How? By using a simple plastic kitchen container. If you germinate your seeds in a plastic container with some damp kitchen paper and you keep it closed, the water from the paper won’t evaporate and dry out. Even if it takes 10 days it will still germinate. Once the seeds have opened, you’ll need to place them in a properly watered pot because you won’t be able to water again until the seedling pops through the surface, although this should only take one day indoors and maybe 2 outdoors. With this system you can germinate hundreds of seeds in a small Tupperware container. If it’s summer and it’s warm, you can just stick them anywhere out of direct light. If it’s the winter and it’s colder you can place the container on top of your TV or internet box to give it that extra bit of heat. If it’s going to be somewhere where light can get to it, cover the box in tin foil.
So, now you know the best way to germinate your seeds. You might have been doing it one of the “wrong” ways and you’ve been lucky so far, but the only way you can germinate and blame the seeds if it doesn’t work is if you use the correct method we mentioned last. Happy growing!
