Indoor marijuana seeds
Outdoor marijuana seeds

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 flavoursome, and produces an exceptionally long-lasting high. BlackJack is thought of highly in the medical marijuana scene.

Personally, to ALL my peeps out there, SHOUT OUT THE BLACKJACK!? Posted by zuvuya4 on 2012-05-16 00:41:53
Yield
Overall yield; inside 11(depending on how you prefer your smoke, I often go the distance for the right plant, that WANTS to keep going, but around 10-11 week mark, is pretty ready and swolen to deserve the extra time!!=for the connisuos) weeks of fruiting/finishing... was about 2.3 oz per plant,x4 plants. I might suggest doing what I did, instead of vegging 4-6 weeks, as usual, try for 8 weeks of veg...the longer the veg, I noticed, slightly higher the yield! I.M.E.
Flavour
Fruity with a spicy yet hard to pin down flavour, overall, very smooth/fruity/with a hint of uniqueness,(thus my overgeneralization of SPICEY)=which is moreat, smooth, relaxing, complex flavour with each pheno of BJack Fem! as with any phenotypes, ya never really KNOW what you'll get, mine all tasted a bit/ to considerably different.
Comment
Overal I would rate the flavour superb, at an 7.5-8.0 of 10!!! The Yield, 7.0 of 10!! And the pant structure, all in all, I rather enjoyed her branching, fairly short internode lengths on 3 of four, the 4th was more lanky... I lost the 5th in the germing process, :(( even using the tried N True Germination Kit and SpongePots. Overall, I will try this strain again!! I shop at only Nirvana's, because they have what I NEED, are FRESH BEANS, ARE AWESOME WITH CUSTOMER SERVICE, AND ALL AROUND PHENOMENAL FEMALE TO MALE RATIO/GERM! Will definatelyRECOMMEND to my Nirvana/other pals!!

It's a fabulous plant when flowering, so many white pistils that you feel like it's christmas already. I've got 7 oz from 4 females of this plant, smoke is very natural/herbal. It was worht a shot to pick this strain.

Such a snowy beauty, cant stop admiring it. Can't judge the taste and quality of smoke since there are not many strains which I have tried, but this one is the tastiest smoke I have ever had, it was not the strongest, but quite a potent smoke.
