Blackjack Feminized

10+ year customer of Nirvana’s here. Dependable and trustworthy company.

I grew 4 Blackjacks under MarsHydro TS3000, flowered for 9 wks; at least one plant could have gone at least another week. Very happy with the yield.

Beautiful chunky buds absolutely coated in crystals; well behaved plants, stretch is moderate and stems strong so minimal staking is needed.

In a vaporizer, at least one of my plants has unmistakable aftertaste of rose, like a light rose perfume. And this was before curing. A Delightful buzz that doesn’t knock you out, if you don’t overdo it. I’ve grown maybe 15 of Nirvana’s strains and this is in the top 10% imo (of course they are all excellent, haven’t been disappointed ever).

Very colorful and has got a strong sweetness aroma in it .

They started out strong all the seeds germinated it was great. However I ended up with powdery mildew on a couple of them. It really overtook the plants no matter what I tried to get rid of it. The buds smelled amazing and I loved growing them. I just wish they were more resistant to powdery mildew.

Indoor grow, flawless from start to finish. selected two phenos, one had an amazing freaky variegation on the leaves and was the star of the room also harvest-wise. Very good yield, very good effects for me, trippy and happy (grown to ~15% amber trichs). Also, minimal waste in the bowl trimmer, love those tight buds. Next time will hunt for a keeper, still sad about not taking a cut from the striped lady.

Only grew 1. Fast and easy grow. Open structure, nice buds and easy to trim. Strong!

i started off thinking i am going to have a real hard time growning this strain.i am in the middle of the frist run and i know i am in love the training is going awsome cant wait till the end of this run i will update.... will try to see how the clones come out also!!!!

I been growing Nirvana seeds for 15 years now, and the Blackjack strain has always been one of my favorites.

Been a Nirvana customer since 2012,,, Blackjack strain is a Perfect Hybrid.. First Off, it's name,,, Blackjack...... After you figure that out,,, it's all Down hill......👌

Really perfect strain........

Each outdoor grow season I try a few new flavors. I am looking for varieties that like my garden and grow well without chemical fertilizer. This is how I found Purple Punch, GSC , Willie Nelson and now BLACK JACK is my newest favorite.

Can't go wrong wit Blackjack.. outdoor grow; nice chunky thick fat Flowers.. euphoric high.... One of my Favorite strains....

I really enjoyed this strain. Every plant was a little bit different but they all had a similar flavor that was very tasty.

This strain is top notch in every respect. Grown multiple times. In my top 5 strains of all time in 30 years of growing.

say goodnight if you smoke it. your eyeballs have a timer.

another well bred cannabis cultivar from nirvana. 5/5

I normally don't review because it's requested before I get a chance to finish the process, but have done BJ in the past and it has been very nice in the terpines, taste and effect, especially after a nice long cure. Tasty and energizing to me, so I was sad to have lost my last clones a few years back and found Nirvana had dropped it AND my all time fav Blackberry. Fortunately it's back, so ordered more, and found Nirvana Blackerry through another source. Never could get a reason nor a hint that they'll ever bring back Blackberry. It was SUPER popular in my circles.

These seeds sprouted very quickly and have grown well in organic soils with natural nutrients added. The plants have grown large and bright. Looking forward to the remainder of the grow out, and cutting clones. She looks like a winner!

Great strain and very strong high as well. Tastes like cough syrup a little but is still pleasant and well worth giving a go.

I grew this strain many years ago. Recirculating hydro using Dutch Gold nutrients. I grew in exploded shale medium. HPS light
I cloned off a mother for two years with great success and minimal difficulty.
I'm trying it once again.
Updated light to an hlg 550 rpsec. Coco coir, Mills nutes.
Has proven to be a bit more difficult this time around. They devour Cal-mag. First batch had a major deficiency, this time I've upped the dose to 10-15 ml/gal.
Produces great dense buds, nice red/orange colors and good aroma.
I added a Uv light for this batch, showed pistols much quicker than without.
Looking forward to final result!

One of the best seeds i got by online.all planted as instructed.

I didn't have great success with this one. It was still a nice smoke, but I can be a bit too casual with my plant maintenance. I might try I've of these harder to grow types again one day

Easy strain for mainlaining and other techniques. This plant dont stop to grow after being cutted. Also perfect for lollipopping as well as for cuttings. Good for beginners who love to experiment with plants. This nirvana strain is pretty stress resistant. Got some rly big nuggets under mainlining in a 15l bucket.

Great all body high, lasting good time

One of my all time favourites. One parent is Black Domina, so no wonder its great. Smooth, mellow smoke, tasty as a fresh blackberry...aewsome!

A++++++++++++++++++++++++++++++++++++++++++++++++++++++ the best ever ++++++++

This is a fantastic strain that produces big buds with sweet smells and tasty flavor.

Blackjack is a wonderful strain grows very quickly and yields huge.

This plant was a beast from the beginning. It was very vigorous and grew fast in the veg and blooming stage took about eight and a half to nine weeks to Bud fully.
