Blackjack Feminized

The specs



Blackjack is known around the medical marijuana community as a sativa-dominate strain that can obliterate away stress, anxiety and depression for hours and hours with its exceptionally long-lasting high.

This makes her a go-to in the morning for a wake and bake session that relaxes you just enough to not couchlock you, while reaping the sativa benefits of a beautiful head high that overcomes you with euphoria and makes you talkative.

This strain is a cross of Black Domina and Jock Horror, so you can expect a nice blend of sweet citrus, balanced with an earthy pine flavor that is incredibly pungent. You can thank her high trichome-encrusted calyxes for her pungent smell too. Those babies have been known to swell up to the size of grapes!

Our tip for this strain:  She is great for coming out of your shell and really helps those that suffer from anxiety. But before you go toking prior to your important business meeting, maybe take a shower first or throw on some extra body spray, because Blackjack is one pungent cannabis strain. Wonderful for phone and skype calls however, so skunk up that room.

What we love about this strain: We are big fans of sativa strains that have a big impact on the medical marijuana community. Often Indicas get all the recognition and while it’s deserved, when a sativa comes around and delivers high THC without inducing paranoia or anxiety we can't help but loving it.

Quote from a customer: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.” - Elijah C.

I grew 1 outdoors. The plant was tall but narrow. Buds were rock hard. Yield was medium. The taste was fruity with a strong peppery aftertaste that mellows after a long cure. A good body stone.

For me, This is a first time grow and has shown quick quick results. Pruning seems to be one factor of necessity. Easy to grow other than that.

Fairly easy grow in a SCROG/HPS hydro setup. This strain had a bit of a chemical smell that mellowed over time but was a little off-putting to me. The high is uplifting with a delayed reaction, so just when you start wondering "Did I smoke enough?" you start laughing. "Yes I guess I did, but I'll have a little more just to make sure..." Love it! Nirvana, you folks are the best! Been buying seeds for a few years now and never once a problem with delivery or quality. Thanks!
