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'ss very own Jock Horror.
BlackJack produces hard buds with huge, grape-like calyxes that are completely encrusted with THC! The smoke is heavy and flavoursome, and produces an exceptionally long-lasting high.
BlackJack is thought of highly in the medical cannabis seeds scene.
