About Black Jack Strain
Overview
Black Jack is a sativa-dominant hybrid, a cross of Black Domina and Jack Herer, known for an earthy, sweet flavor and an energizing, balanced high. It typically tests between 15% and 20% THC. Combining Black Domina's dark, dense bud structure with Jack Herer's clear, cerebral energy, it produces a strain that leans sativa in effect while carrying real visual and structural influence from its indica-leaning parent.
