PL THE PLANT
BotanyGeneticsFoundations
Cannabis is one plant with an unusually rich chemistry and a long human history, and it makes the cannabinoids and terpenes people use it for. Everything starts with the plant. These pages cover what the plant is, how it is built, how it makes the compounds people use it for, and where it came from. It is the foundation the rest of the encyclopedia builds on, from cannabinoids and terpenes to strains and recipes.
