Providing you are in a country that allows the germination of cannabis seeds, the best way is to germinate your seeds in a glass of water or damp paper-towel and then use Jiffy peat pellets. Soak the pellets in water, (ph-balanced water), and when they have expanded take them out and allow them to drain off. Then place each sprout just under the surface (one germinated seed per pellet). Leave them in the dark for 1-2 days and keep an eye on them to see when the sprouts start to show. Do not let them dry out. Once they pop place them in a propagator and use a strip/fluorescent light for 18 hours a day, placed 2-inch's above the propagator. Do not use a strong light and keep the temperature around 21C/70F. You should see a +/-90% sprout rate using this method.
