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%. Black Diamond sets itself apart with medium to large flowers that have an elongated, almost cylindrical shape. The buds have the dense, solid structure characteristic of other indica varieties. Leaves are a pale sage green and are shot through with pale brown pistils. Some phenotypes of the strain also have vibrant streaks of purple, which are the result of pigments called anthocyanins that have been stimulated by cold weather during the growing process. Icy white trichomes are the crowning glory on these striking flowers, giving them a very sticky texture and making them difficult to make them break up by hand.
