BlackJack’s mother, Black Domino, was a clone of a marijuana plant sent to the Netherlands from the area around Seattle. Its father is Nirvana’s very own Jock Horror.
Nirvana BlackJack produces hard buds with huge, grape-like calyxes that are completely encrusted with THC! The smoke is heavy and flavorsome, and produces an exceptionally long-lasting high. BlackJack is thought of highly in the medical marijuana seeds scene.
