Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.
Was the seed found in good weed?
To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.
To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.
WET KITCHEN TOWEL METHOD
You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.
Small, fragile, and in desperate need of a helping hand, there are several ways you can germinate your cannabis seeds. All methods have varying degrees of success, with both advantages and disadvantages. It is important to note that even with advanced growing expertise and top-of-the-line equipment, you may still end up with a few failed seeds. This is a natural part of dealing with a living organism. At Royal Queen seeds, we only sell feminized cannabis seeds, so there is no need to worry about removing male plants.
Timescales can vary, as it all depends on how ideal your germination environment is (see the golden rules above). Even the worst grower could make a seed germinate, but it may take a few weeks and, of course, increases the risk of a weaker plant.
Place one sheet of damp kitchen towel on a flat surface. Space your seeds a few centimetres apart before placing the second piece of kitchen towel over the top. You need to ensure both pieces are damp, not wet. Once again, when the white root tips reach 2–3mm, move the seeds (carefully) to soil pots. Use the same guidance found above for planting techniques.
Only a day or so has elapsed between the first sight of the root and the appearance of the cotyledons.
You can see the pericap of the seed still on top of the embryonic leaf, the cotyledon. The first true leaves are visible above the cotyledon. Cannabis seed photo by Professor P of Dynasty Genetics.

Methods for germination
After soaking you can place the seed between a thin wet cloth or paper towel on a plate with a clear cover or plastic wrap. When the root emerges, plant it by first poking a hole in the planting mix that is long enough for the entire root area to be covered. Then gently place the seed and pat it so the root makes contact with the medium. The other method is to plant the soaked seed into the medium before it germinates. Place it ¼ inch deep in sterile commercial planting mix. Moisten the mix with water adjusted to a pH of around 6. Keep it in a bright space with high moisture. If the space is dry, place a tall cover over the container to reduce evaporation. Keep at room temperature. If the air is cool, use an electrical tray warmer and cover.
Once it has made contact with the requisite amount of moisture and proper range of warmth, the seed starts the process of germination. A cascade of chemical reactions results in the rapid growth of the embryo plant, which had been kept in suspended animation.
In its first phase of growth the seedling used energy stored in the seed, but it must soon use photosynthesis to produce its own food as its roots supply moisture and nutrients The root grows longer and lateral branches grow from the vertically growing tap root. The first set of true leaves emerge at the tip or apex of the stem, which is called the apical tip.
Germination begins when the root emerges from the seed. These germinated seeds are ready to plant.
