Three different kinds of sativa
The three are related only loosely. Jack Herer carries Northern Lights in its family tree. Durban Poison is one half of Girl Scout Cookies, which makes it a grandparent to most of the dessert strains on a modern menu. Green Crack’s notes are mango, skunk and citrus, and Weedmaps reports it was first called Cush.
