Black Diamond is a hybrid with mostly indica genetics. It is a cross between flavor-engineered Blackberry and Diamond OG, a hybrid derived from OG Kush. This strain delivers a strong, sedative high that still allows for mental lucidity, making it great for concentration and conversation. Aside from its psychoactive potency, Black Diamond also has definite bag appeal, with multicolored flowers and a dynamic, robust aroma. This indica’s THC index has been measured at between 15% and 24%.
