How to Germinate Marijuana Seeds
Germinating Marijuana seeds is simple and easy to do. In order to grow cannabis plants from seed, this is the first step in the process. All you need is a few seeds, some paper towels, tupperware, and a bit of water.
Step 1: Identify germination ready marijuana seeds
You can’t germinate any old seed you find in your cannabis flowers. They need to be a certain age and have a specific look in order to burst open and begin the plant’s lifecycle. You generally want to germinate seeds that are dark and have black stripes. See the above photo to have a better idea of what they look like.
Step 2: Dampen a few paper towel squares
Depending on the amount of seeds you are looking to germinate, you will want to dampen a few paper towel squares. You do not want them to be dripping water but wet enough to provide the correct amount of moisture to the seeds.
Step 3: Place damp paper towels in a Tupperware container & place seeds inside
Open your Tupperware container and place 1 or 2 damp paper towel squares inside. You will want to evenly disperse the seeds around the paper towel.
Step 4: Cover the seeds with another damp paper towel and close container
Once you are satisfied with the spacing of the seeds, place another damp paper towel over the seeds and then close the lid to the container.
Step 5: Wait about 2 days
You should see the seeds start to split in about 2 days. There will be a little tail looking thing coming out of the seed. This is the beginning of the plants root structure!
How do Cannabis Seeds Work
How do cannabis seeds work? You might not think that this is important, but knowing how seeds work can give you important insight on how to store them and what the germination profess involved. Cannabis seeds are technically small, oval-shaped dried fruit, around 3-4mm long and 1.5-2mm wide. They’re covered in a very subtle membrane, and underneath that layer there’s a much harder layer which is the largest system of the embryo, covering it and protecting it.
On the inside of the seeds you can find a substance called albumen, which is a nutritional reserve that keeps the embryo healthy until germination; it’s also the seeds initial source of energy once it begins germinating.
Now, for the center of the seed, home to the precious embryo from which your new plant will grow from. It contains the plant’s genetic code alongside four other parts; the radicle, the hypocotyl, cotyledons and gemmules. The radicle is the embryonic root; this is the part of the seed where roots come from. The hypocotyl is known as the embryonic stage, and the cotyledons are in charge of those first few leaves that you can see once the seed germinates.
Cannabis seeds, just like many other plant seeds, grow in pollinated flowers on female plants; seeds only contain the plant’s genetic code, so they don’t have any of the active principals in the plant, meaning that if you were to smoke it you wouldn’t get any sort of psychoactive or medicinal effect. They can be eaten however, as they provide an enormous amount of beneficial proteins, including Omega 3, 6 and 9. The aroma that comes from the seeds when burning isn’t pleasant at all, and if you’ve ever been smoking a joint that had a random seed in it then you know exactly what I’m talking about; they taste like some sort of burnt barbecue that ruins the taste of even the best, strongest tasting weed out there.
Germinating seeds correctly depends on different factors; the main one being how mature the seed is. Seeds that look too white, green or the skin seems to be coming off or not there at all tend to be too young still, although there are seeds of this stature that will germinate perfectly, depending on the strain. Strains like Somango, or hybrids that come from it, and Haze seeds are some of the whitest seeds you can find on the market; sativa seeds tend to be much smaller than indica seeds, like Thai seeds are generally much smaller than afghan seeds. In this case, size doesn’t matter at all; if a seed is smaller than others that doesn’t mean that it’s going to have issues germinating or that it will grow smaller plants. Smaller seeds generally have less protection, but they’re much easier to germinate. Seeds can take between 3-18 days to germinate depending on the conditions such as temperature, humidity, substrate composition etc. The longer the seeds take to germinate, the less likely that they are going to germinate. Sometimes if after a while it still hasn’t germinated, you can gently squeeze the seed to break the outer shell and if done right, you can help the root to leave the shell; if done wrong, you’ll end up completely squishing the seed and any chances of germination that it had.
During the time the seed is maturing various factors need to occur for the seed to be able to germinate in the best conditions. Seeds have a germination period of three years, which is the average time estimated that seeds can be kept in good conditions; it’s not the same to keep your seed in a fresh, dry area than in a hot and humid one. Humid areas will damage seeds, stimulating their metabolism with the humidity without stimulating germination which could even kill the seed off entirely. Water absorption is due to the water potential difference between the seed and its surroundings. Water reaches the embryo through all of the layers of the seed, which then activates the development of the radicle; once this process begins, seeds need more oxygen than water, so giving your seeds too much water might in fact “drown” them. This is why we highly recommend not germinating your seeds in glasses of water, as the oxygen-water ratio is nowhere near optimal for germination.
By lowering oxygen levels as well as temperature storage levels you can increase the life-span of your seed for up to 20 years. Another storage technique is to dehydrate the seeds around 2-5%; no more is recommended as it might affect the internal constitution of the seed. Temperature is extremely important as it regulates the activity of the enzymes during germination; during storage, temperature regulates the embryos metabolism.
Oxygen is found in nature in a concentration of about 21%; seeds tend to germinate in conditions with around 20-21% oxygen, and hardly any seeds can germinate with a lower concentration than that; the only plants that can really do that are marine plants and algae, which need 8% oxygen.
Now that you know how cannabis seeds work, you can store your babies for up to 20 years if you want to, and give them the perfect conditions in which to open up their shells and let the radicle take over growing the roots. Happy growing!
