OG Kush, also known as “OGK,” is a slightly sativa dominant hybrid strain (55% sativa/45% indica) with unknown parentage due to breeder secrecy, although it is thought to be a cross of the iconic Chemdawg X Hindu Kush strains. Probably the most famous strain in the world of medicinal marijuana, OG Kush is the perfect hybrid for any indica or sativa lover.
