Pure OG is a California-bred, (potentially) fairly potent (THC levels reported ranging between 14-22%), just-about-ready-to-sleep, Indica-Dominant, nighttime hybrid descendant of either OG Kush or (essentially) San Fernando Valley OG Kush. Blissfully sedating, this pine, cheese, skunk, coffee and mango strain does one job really well so it would be wise to prepare a bed.
