What is the Black Jack strain?
Black Jack is a hybrid cannabis strain with up to 25.0% THC, known for its relaxed effects and citrus and earthy flavor profile.
Black Jack is an indica-dominant hybrid cannabis strain created through the crossbreeding of Black Domina and Jack Herer genetics. Bred by Sweet Seeds, Black Jack is a cross of Black Domina and Jack Herer, though there is also a similar variant created by Nirvana Seeds using Black Domina and their proprietary Jack Horror strain. The strain exhibits typical cannabis ratios of 70% Cannabis indica and 30% Cannabis sativa genetics, resulting in a well-balanced hybrid experience.
The strain is characterized by its thick buds with huge calyxes that are completely encrusted with trichomes. The nugs of the Sweet Seeds variety are larger and denser, sometimes with a purple tint to the leaves. Plants typically grow to medium height indoors but can reach impressive sizes outdoors, with about three meters of height when planted outdoors, directly in the ground and with enough sunlight. Black Jack has gained recognition as one of the most potent and productive strains in the cannabis community, earning multiple awards and widespread cultivation by both commercial and home growers.
