About Blackjack Feminized

Hard buds with THC-encrusted calyxes the size of grapes.
Extremely long-lasting high.
Very tasty, heavy smoke.
Great medical strain. 

BlackJack’s mother, Black Domina, was a clone sent to the Netherlands from the area around Seattle. Its father is Nirvana’s very own Jock Horror. Black Jack 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. Black Jack is thought of highly in the medical cannabis scene.

I only had one tent when I grew these, so only grew 2. LOVE the taste, the smell, and most importantly the relief from my spastic legs! Blackjack was hearty grower, made some mistakes trying to top them, and they bounced back fuller and healthier than they looked before topping. Wonderful choice for medical and recreational! I will grow these again after my bubbleicious. Thanks Nirvana!

A very special breed, but it's worth noting that the most powerful flavors that can not be described, just Championships, big thanks to Nirvana !!!

I just have brag. I grew my Blackjack in the wonderful sun of New Mexico USA in the ground. Not a pot. Always grow in the ground. My Blackjack grew to 10 feet high and 8 feet wide all around. Wonderful smoke with great yield. The cola's are dense and big. Just like the plant. I did no cutting on it and let God do the work It look as if it had 4 tops. Thank you Nirvana.
