Black Jack is a name applied to two strains. One strain is a cross between two Sensi Seeds parents — the mostly indica, Afghani landrace-derived Black Domina and the more balanced Jack Herer. The other Black Jack strain (sometimes spelled Blackjack) was created by Nirvana Seeds. This latter Blackjack is a cross between Black Domina and Jock Horror, Nirvana’s own spin on Jack Herer, which is sativa-dominant cross between staple strains Northern Lights, Skunk, and Haze. The THC composition of these Black Jacks cumulatively ranges between 15% and 20%
