As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:
Growing your own weed is fairly easy, as explained in our article ‘All You Need For Growing Weed At Home‘. The hardest part for some growers though, is germinating their newly bought cannabis seeds. After all, the vulnerable seedlings are easily damaged. However, making sure your cannabis seeds survive germination is essential for a successful grow. In this blog, we highlight three tested methods that let anyone germinate cannabis seeds with minimal effort.
The goal here is to balance out the moisture so it’s not too dry, nor to wet. Go for a piece of paper that is moist all over, but doesn’t drip when you pick it up. If the seeds stay to dry, the root that’s supposed to sprout won’t be able to make it out of its shell in search for water. If the paper is too wet though, the root will come out and quickly stop looking for water; as it’s already soaked in it. This stops the development of the root, delays the growth and might even cause the seeds to rot after a while. So, be careful not to give too much water as this is one of the most common rookie mistakes when it comes to growing weed!
How To Germinate Cannabis Seeds, Step 1: Get Good Genetics
Germination is actually a process where you activate a dry seed that is in a ‘sleeping state’. By adding water to the seed, a small root that is inside the seed-shell will want to come out in search for more water. This will make it develop into a big taproot that’ll serve as an anchor for the plant and from which more roots will sprout.

So there you have it: whichever method you chose, germination should now be underway. Remember that even the best seed banks work with organic, natural materials, so 100% germination rates can never be guaranteed. If you get your technique right, though, most or all of your seeds should germinate according to plan. Once your seeds have become seedlings, the next steps of your grow await. There’s a lot of choices to make from here to harvest time: indoor or outdoor, which spot to pick, what nutrients to use, and so on.

Last but not least on this list is the germination of cannabis seeds in special plugs. These plugs are available in various materials, especially designed for quick and efficient germination of cannabis seeds.
