Description for Black Jack

Black Jack is a heavy yielding sativa-dominant hybrid, that produces large dense flowers with big calyxes covered in crystals. Good for both indoor and outdoor grows alike, this plant stretches like a classic sativa and will require topping for indoor and a lot of vertical space. Easy to grow yet needs proper care of defoliating and trellising as it has the tendency to get top heavy.  With a strong, delicious flavor with long lasting effects from high-levels of THC, Black Jack is an industry favorite among medical patients.

Wow how nice. A lot of work but worth it.

By Jeff Sarbak on November 26, 2018

Smooth and lovely flavors of pine, melon, and meaty muskiness similar to Alaskan Thunder. The effects are happy, upbeat, social, with no couch lock, and a very zen brain fog but in a good way. Calming and good for Thanksgiving.

First blackjack grow

By Tyler on October 2, 2018

I just harvested my first of three blackjack plants 2 days ago. This was one of my favorites this year. I topped it early and got about 8 really good sized colas (coke can thickness). While my pictures look different from theirs, it is definitely a good yielded and I will definitely grow it again. The colas are significantly longer than most of the other strains and they’re more dense than some of my others. I would urge fellow growers to be patient as she puts on a lot of weight in the last couple of weeks. This was an incredibly hearty and resilient plant. Grown in soil she hardly showed symptoms of deficiencies even after two weeks of flushing!

Black Jack Decent Mold Resistant Nuggy Strain

By JesusSaves on August 20, 2018

J1 memories made a candidate to rate and rank a friends harvests. If you cannot get real J1, this might satisfy you. Is one of the better strains this site i say. Bend the top severely instead of topping it, to even out canopy. The buzz is a very mild cerebral type, and you will never lose your car keys with it i promise.
