To germinate cannabis seeds, is the process of getting your seeds to sprout. When the seed begins to sprout you will see a small tendril (usually white in colour) that pops out of the seed.
That small white tendril that breaks out of the seed when germinating cannabis seeds is your plants very first root. This root is also known as the taproot. This is the main root of the cannabis plant and every other root it produces will grow off the taproot.
The taproot of the cannabis seeds will begin to grow longer. As it grows longer the seed will get pushed upwards. Eventually the shell of the cannabis seeds will push up through the growing medium you have used. The first leaves are known as “cotyledons” and they will begin to appear soon.

How to germinate cannabis seeds: step by step guide
In the first step you need to soak the cannabis seeds in clean water for around 12 – 24 hours. A small glass or container would be perfect. When you first put the seeds in the water, you will notice that they float on top of the water. After a few hours the seeds will slowly drop to the bottom.

The reason growers soak the seeds is so that the water can get into the seed through the protective shell. It also helps with activating the growth hormones. If you soak the seeds you are germinating for too long, they could end up drowning due to oxygen deprivation.
12 – 24 hours should be plenty of time for your seeds to soak.
The next step is to remove the seeds from the water. Get 2 plates out the cupboard and line the bottom of the one plate with a paper towel. Now pour the seeds onto the paper towel. Make sure the towel is totally wet, then pull the towel over to cover the seeds.
Take the plate to the sink to drain out all the water around the paper towel. Tip it and make sure that all access water has been removed from the plate. You want the towel moist not soaking wet.
Find a location to leave the seeds for a while. Ideally you want a warm place that is dark or at least shady. The optimum temperature is around 21 – 25 degrees Celsius.
The paper towel should be checked once or twice a day to make sure that the paper towel is still moist. Depending on the temperature and humidity of the area you have placed your seeds, they might need some more water. Check the seeds once or twice a day.
NEVER let the towel and seeds get dry or dry out. Seeds should not sit in water either. Make sure to drain any excess water added to the paper towel.
Germination should take place in around 36 – 96 hours if all goes well. Some of the seeds will germinate quickly where as others might take a bit longer. Often older and weaker cannabis seeds take a bit longer to germinate.

Keep it moist – Make sure that the cannabis seeds are kept moist but not soaking during the germination process. On average you should soak the seeds for 24 – 32 hours. They shouldn’t be left to soak longer than that. By keeping them wet and not moist you could actually drown your seeds.
Leave them alone – Make sure to not disturb your seeds while waiting for the taproot of the cannabis seeds to grow.
Keep it warm – You want to make sure your seeds are kept warm. If you live in a warm climate, this is not a problem. Colder climates might require you to get a heating pad to get the same results.
Be gentle – Always be gentle with new seedlings. Do not touch the white taproot they produce. It is very fragile in the early stages of its life.
Taproot down – Make sure you plant the cannabis seeds with the white taproot facing downwards. Doing it this way will prevent the root from having to reorient itself when growing.
(1cm – 2.5 cm) deep – Make sure the seeds have not been planted too deep in your growing medium. They should be planted just under the surface where not much energy is used to pop through the surface.
