The availability of an auto-flowering version of the Critical Mass cannabis species is the result of an intense and diligent breeding programme. By crossing the auto-flowering properties of ruderalis with the massive yielding, and high quality Critical Mass, Barneys Farm breeders have developed a most potent strain that will commence flowering within 20 days of planting and finishes in as little as 8-9 weeks. Typically the plant will grow 0.5 meter, with a main stem and 7 side branches, all full and dense with long fat colas of delicious indica marijuana.
