Light is not required
and may slow or hamper the speed of germination. There are many methods for supplying these requirements and in this article we shall examine several of them.
Paper towel method of marijuana seed germination
This popular method requires a paper towel (or paper napkin or tissue paper) cut in half with each half folded in half. Place one half on a small dish and moisten. Both halves of the paper towel should be damp, but not dripping wet. If you have over-watered, be sure to squeeze out any extra moisture.
Place your seeds on the towel and allow roughly ½” of space between them so that the roots do not get tangled. Cover with the other half of the paper towel making sure it is in contact with the seeds.
Finally, place an inverted dish of the same size and type as the bottom dish on the top. This is to keep the marijuana seeds in the dark and the humidity high.
Get a thick kitchen-style paper towel and wet it thoroughly. Make sure it isn’t dripping though;
Place the blunt end of the seed onto the towel and leave it making sure it does not get any direct sunlight. You don’t have to cover the first piece of towel with another piece;
Keep the seeds at about 70°F to 85°F (21°C – 29.4°C) like at the top of the refrigerator (a warm zone). Make sure the towel never dries out or you will kill the seeds;
Check them twice a day until you see the seed case split and the emergence of a tiny root at the bottom and a white shoot at the top;
Usually all viable seeds will have opened within 48 hours;
Be very careful handling them at this point. They are very fragile;
Once you can see the root and shoot, plant the seeds on their sides in the growing medium of your choice.
Make a small hole ready for them rather than forcing them in with your fingers. Plant them about half an inch (1.25cm) deep, cover them gently with the growing medium and give them water, but not too much.
Check every 24 hours –
Most seeds will ‘crack’ (break the outer hull) in 1 to 7 days. Once the tap root is ¼” to ½” long the seeds will be
48 – 72 hours –
The first small root tip which is known as a radical will form as the water is absorbed into the seed;
10 – 14 days –
You start to see the first roots appear;
21 – 30 days –
The best seeds are rooted by this stage and any that are not will grow slowly and poorly and are probably not the best to keep.
