Black Jack is a luscious indica-dominant combination of popular strains Jack Herer and Black Domina.
This strain combines the productive and focused traits of its father strain (Jack Herer) with the fully relaxing and euphoric effects of its mother (Black Domina).
These buds have a distinguished appearance, as its buds are a mix of deep green and bright purple, with rust-colored pistils and a hefty coating of potent trichomes, and an aroma not unlike a pine tree.
