Blackjack

Cannabis Strain by Nirvana Seeds

Introduction
Blackjack from Nirvana Seeds is an indica/sativa hybrid completing in approximately 70 days of flowering—notably longer than some Blackjack varieties—representing Nirvana's extended-development interpretation of Jack-lineage genetics, trading speed for additional terpene complexity in their accessible Dutch genetics catalog.

Lineage
Nirvana Seeds has been offering affordable cannabis genetics since 1995, and their Blackjack follows the Jack Herer/Black Domina concept with an extended 70-day flowering period. This longer development time suggests Nirvana's version either incorporates more sativa genetic influence extending flowering, or simply selects for maximum aromatic development over efficiency. The Jack Herer heritage (Haze × NL5 × Shiva Skunk) typically adds complex pine-spice-earth aromatics and cerebral clarity while Black Domina genetics contribute indica potency and hash depth.

Terpenes
The 70-day flowering window for this indica/sativa hybrid allows the complex terpene profile of both Jack Herer and Black Domina genetics to fully develop. Nirvana's accessible pricing and established reputation make this suitable for cultivators who want the Jack × Black Domina concept without boutique pricing. Expect moderately dense flowers with the characteristic Jack-lineage pine-spice-earth aromatics balanced by hashier, deeper notes from the indica component—a reliable, if less cutting-edge, interpretation of this beloved genetic combination.
