Terpene profile
Terpinolene, Myrcene

Black Jackยฎ (SWS01) is one of Sweet Seeds’ most powerful and productive strains of cannabis. It’s the result of a crossbreed of their Black Domina with an exceptional Jack Herer that features a pleasant and intense bouquet similar to the Hazeโ€™s cathedral incense aromatic trait.

This classic strain features great hybrid vigour and it is totally adapted to indoor grows. When planted outdoors, directly in the ground and with enough sunlight, it becomes a resinous hairy monster, reaching around 3m of height.
