A basic overview of how cannabis seeds are made, the differences between the types of seeds available, how to identify mature seeds, and how to store your cannabis seeds.

The Seed Banks I have experience with and recommend are:

True North Seed Bank: http://truenorthseedbank.com?a_id=59cacf0234039 (Located in Canada)
Seedsman: https://www.seedsman.com/en/cannabis-seeds/?a_aid=59cace7bccd9a (Located in Europe)

Both of these seed banks offer shipping throughout the world.
