First of all, we need to understand the anatomy of a cannabis seed.
It consists of a plastic base with small square cells (can come with up to 256 cells, each cell supports 1 seed), on top of a heat mat, also comes with a humidity dome, basically looks like a small greenhouse. They’re very cheap and you can make one at home.
1. First Things First: Know the anatomy of your cannabis seed
Those leaves are responsible for feeding the plant until the first set of true leaves appear.
To germinate in either one of them, we will use the same technique explained before, moisten the Rockwool or peat pellet, make a little hole (1-2cm) and place the seed inside, cover it gently without applying pressure and you’re all done.
Place the container in a slightly warm and dark place.
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.
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.
Now you know all about the germination of autoflowering hemp seeds, but these procedures can also be applied to feminized and regular seeds.
Temperatures and germination time of self-flowering seeds
Not only the temperature, but the water on which the seeds feed is also essential for high quality and fast germination.
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.
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).
Here are the main reasons:
The pH value of your soil will determine how well your plants can access the nutrients within. If the pH becomes too high (alkaline) or too low (acidic), nutrient lockout will occur and deficiencies will set in. Cannabis plants thrive in a soil pH of between 6.0 and 6.5. Use a pH tester to track pH throughout your grow.

Next, poke a 10–15mm hole into a pot with your soil mix. Sow your seed directly into its final pot to avoid the stress of repotting later down the line. Transplanting causes plants to go into shock, and autoflowers grow so fast that they’ll struggle to recover. Place a seed in the hole and cover lightly with soil. You’ll see your seedling emerge in the next few days.
A NOTE ON PH
However, their yields aren’t as spectacular as those obtained from photoperiod giants, but, the trade-off for brevity makes the decision worthwhile for most growers.
Many growers elect to cultivate autoflowers because of their speedy growing rate. Their hardy genetics and forgiving nature also make them easier to grow and therefore more beginner-friendly.
Germination usually takes 1–3 days. During this time, your seeds will activate and send a root down into the soil and a shoot above the surface. To begin the germination process, you’ll need to prepare a suitable soil mix. Autoflowers don’t need as much nutrients as photoperiod varieties and prefer light and airy soil.
After you’ve prepared the mix, add some Easy Boost Organic Nutrition to the blend. These pellets will slowly release adequate levels of nutrition into the soil, providing foundational elements and minerals for the entire growing cycle. Add some mycorrhiza to the soil to help your plants flourish later down the line. These symbiotic fungi will bind to the root system and help your plants uptake nutrients more effectively.
