Sour Cookies is a Mamiko Seeds creation, a cross of the Riri Cut of Reservoir Seeds’ Sour Diesel and the ever popular Girl Scout Cookies. True to its name, the strain has a sweet and sour cookies flavor profile.

Sour Cookies grows quickly indoors or out with long branches between nodes. Screen of Green (ScrOG) and pruning are recommended by online sources. The cultivar is ready for harvest in nine-to-10 weeks inside or in mid-October outside. Breeders should take note of Sour Cookies’ two phenotypes: its colas are small, compact, resin-heavy, and very leafy in one, while the other’s colas very large and nearly leafless. Online sources report a good yield with this cultivar.
