If you want to continue growing a strain that you enjoy, cloning is your best option. You could also continue the strain by breeding two plants to produce seeds. You won’t completely replicate the strain again using the seed method, however, unless the two parent plants are from the same IBL (inbred line). Even if the two plants are not IBLs, they should produce seeds that contain most of the parents’ features. If you want to create a plant with characteristics from two
different strains, breeding the marijuana from seed is your only option. That is the subject of this chapter, which begins with an introduction to simple breeding procedures and then goes on to cover advanced techniques like breeding a true strain and backcrossing.
How easy is it to make seeds? It’s easy if you have healthy plants and a stable growing environment. When your male plants burst their pollen sacks in your grow room they’ll pollinate the female flowers. You can also administer pollen directly to your females if you prefer.
COLLECTING AND STORING POLLEN
Pollen can be extracted from male flowers as soon as they open: you’ll see the male flower open out from its calyx. It is best to gather pollen after it falls from the pod onto the leaves. You can shake the pollen onto the female flowers to pollinate them or grow your males separately and store their pollen for future use. Film canisters are great for storing pollen. You can save pollen in a canister for the next harvest. Although it can be stored in the freezer for as long as 18 months, pollen is best used within six months of collection. Pollen has been known to keep for longer than 18 months, but is usually not viable past this time.
