Blackjack Feminized
  • Black Domino / Jock Horror hybrid.
  • Hard buds with huge, grape-like calyxes.
  • Exceptionally long-lasting high.
  • Highly-thought-of medical marijuana strain.

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 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.

I would have given it 5 stars, but it's just 1 week sprouted so far. But she looks strong already! No pre-treatment of the seeds, just put two seeds in 2 pots and kept them watered. took 2 nights and by the 3rd morning I had 2 little blackjacks smiling up at me. :) Can't hardly wait for her flowers! :)

I won't waste too much time talking about shipping or germination because we all know nirvana is great at both...that being said I'm growing two plants in one 2x4 grow tent with two 150watt hps lights. Right now I'm in week 7 of flower and both look amazing. One plant looks like it will finish before the other. The stretch when starting to flower was good sized so I recommend star starting early.Will post another review after harvest

Blackjack's smell is like you're taken to wonderland. This smell is so unique that you want the stay whole day beside your Blackjack and that you want to say: Blackjack I love you so much lol. This smell is so ....so....UNIQUE. I grew DWC under Leds. She is very easy to grow and I had no leaves issues; this plant is very healthy, a little bit small roots but healthy roots. She likes to keep ph stable and loves clean water every week. I had small flowers, my led was not 100% as it should be, although she had very sticky buds. I germinated two seeds and both sprouted within two days. Healthy seeds. I lowstretched trained this plant and she is all right with it. They started very small but the stretch made everything oke. Blackjack is on my list!

Beautiful, beautiful seeds. First time trying to grow my own meds, tried napkin germing but I think I fried these beautiful babies with the 300 watt 3700 lumen bulb I had them under. I'll be ordering these again, but with the propagator and germ kit.

This was my first time growing for my own medical use so I didn't expect much. Glad I was wrong. I grew 2 black jack fem in 50/50 perlite/coco with nutes that my dad gave me. Grew under 400W HPS/MH. Ended up with over 2oz. per plant. Maybe closer to 3oz. but we smoked a jar before I weighed. Cured for 4 weeks in jars. Great smoke, flavor, and effects. Works great for my pain and insomnia as well as my anxiety and PTSd. Thanks Nirvana, I was so happy I ordered 4 other different strains and will report on those as they finish.

This is by far one of my favorite strains to grow! I have never had any nutrient issues, cloning issues, repotting issues, training issues. This strain is VERY forgiving. I love how you can tell it's a blackjack by the giant fan leaves during veg. this is one plant I have never had to label. this plant is very strong, never had to stake it despite its enormous colas. it likes to be be topped and supercropped and lollipopped. get rid of those lower branches. I also found this plant defoliates itself! When leaves get in the way it literally will show you what leaves to pull off before flower. Such an excellent strain indoors and even better outdoors. Indoor yield with soil, cO2, organics around 8 oz cured. Outdoor with soil and organics in the open air around 16-18 oz per plant. this is a BIG WIN.

Blackjack needs alot of attention in the first days, but my strongest grew 3 feet. Nothing bad to say about this strain except harvest a little early and get higher than high.

Grew three plants; one in a popular bubbleponics system and two in a janky homemade five gallon bucket with nutrients from the Advanced Nutrients "Grand Master" line of nutes. The popular Aeroponics system was blown away by my janky homemade bucket bubbler, and while my lack of experience (second grow) prevents me from saying that the full AN line that I used made a difference, these seeds produced some amazing, beautiful plants that grew thick and tall AND survived my negligence- I went out of town for a few days and the girls drank all of their water and were completely wilted upon my return. I added water and nutrients, and a prayer to Jeebus, and they bounced right back. From seed to harvest was about 110 days, and the yield for an occasional smoker/non-seller like myself was stellar. I've had friends over who are regular buyers and to a person they have told me that to get weed of this quality from their normal sources they would easily pay four to five hundred dollars an ounce. Bottom line: this is a hearty, exceptional strain with an amazing body stone that will prevent you from doing much other than hanging out, enjoying tasty snacks and making even the simplest of television incomprehensible. It gets significantly more potent and more fragrant as it is cured, and I would definitely grow it again if I wasn't so interested in trying out Nirvana's other great varieties. I have grown this, the Bubbleicious, Northern Lights, Papaya, and a Blue Mystic autoflower (all feminized) and to a plant they were all female and all germinated quickly and easily. It is hard to choose between this strain and the bub to pick my favorite, but it's up there. You cannot go wrong with this strain.

No LST or topping, and grew baseball bats that needed support. Had white mildew on leaves, easy to wipe off. No mildew on buds. I love the way it grows, not too tall and with very large buds and colas. It's possible I'll grow this exclusively at some point. It's high quality (smell and taste), has a nice heady high, and grows short and fat. I love Blackjack. I also love Nirvana and have never had a shipping issue with them.

This strain worked pretty well even for being in a northern region where the first frost starts around the end of September. Luckily, most of the trichromes changed right around the same time. The aroma was a little strange when I fist started drying them. It was like really sweet smelling and kind of weird. After it began to cure for a bit, though, that smell actually turned out to be a good thing. It became much more subtle and was an added value to the crop because it infused an almost earthy sweetness into it.

Overall I was extremely happy with this strain. If you are in a Northern region, though, make sure to time out when to stop adding your bloom nutes really well because you don't want to have to do a quick harvest due to frost with too much of that fertilizer in there. If you live in an area where the frost comes in in mid to late October or later you're definitely in the clear. At the same time, though, this strain will utilize a lot of P and K at the end, at least, this was what I found for the soil conditions that I had. In the last few days before harvest I did notice a little yellowing of the leaves. I thought this might have been due to a lack of nitrogen but it could have just as easily been attributed to the nights that were beginning to get cold. It really was too late for it to matter or do anything about, anyway.

Try out this A+ strain!

Grown this strain a few times, has the tendency to get branchy but grows fast. Has fairly long inter node length but forms very solid colas at its tops. This plant is a carbo muncher, its one of those strains that forms deficencies if the proper nutrients and carbs are not present which isn't a big deal but your plant will lose potency without a good carbs on its menu.

only grew 2 along with white widow, next time i will start blackjack 2 weeks b4 widow and over veg them. they list this as a med hight plant, i would lean more tward calling it short. widow towers above blackjack. plant is so thick it looked like a basketball ontop of a 5gal bucket. needed to trim to avoid problems. But the smell is fantastic, if i had to describe it id say. it smells like someone filled a stinky tennis shoe full of lemon drops . but in a good way. lol great seeds . got them 6 days after ordered. thumbs up Nirvana!!!!

Nicely done Nirvana!
I received my order in 8 days... all five feminized seeds germinated. These are really beautiful plants too.... I had one pheno in particular that yielded almost 8 ozs per plant.... seriously! One huge main cola with multiple side colas that were nearly as beefy as the main.
Great genetics... smooth smoke , great buzz... lots of pain relief.

I took the risk with cash and was duly rewarded. The cash arrived and Nirvana immediately sent the product to me. It arrived within five days of Nirvana's receipt of payment. I couldn't ask for anything more.

Honesty in an internet cash transaction is not always the norm. As such it's quite satisfying to transact a little business with people who run their shop with dignity and professionalism. Kudos.

I am very cautious on any online purchases. I was even more so here being a first time buyer. I placed my order for the BlackJack after reading various reviews, but still felt apprehensive. Sure enough, approximately two weeks later, they arrived. Nirvana yall' brightened our day. Your packaging too, brought a big smile to my husband and myself. Thank you!
