Black Jack autoflower is a fast-finishing variety with a genetic makeup of 70% sativa, 10% indica, and 20% ruderalis. This strain results from crossing Jack Herer with Black Domina. Perfect for novice cultivators, it offers moderate resistance to mold and thrives in both interior and exterior growing environments, completing its cycle in 42 to 49 days.
