BlackJack’s massive, grape-like nuggs are clear winners. These impressive cannabis seeds are covered from top to bottom in potent gems – they’re tight, sticky & extra-dank!

She sounds like a dark beauty, but BlackJack Feminized is actually an important part of the legendary “White” family along with other classic strains like White Widow & White Rhino. The name might fool you, but her oozing resin reveals her pedigree every single time!

  • BlackJack is a Stable Feminized Seed
  • The Tastiest MMJ on the Planet
  • Enduring, Effective Highs & Stones
  • Totally Dank & Very Affordable

Nirvana Seeds’ BlackJack is highly sought after for her strong medicinal properties, but recreational collectors lover her too. With both Indica & Sativa genetics, she’s a real hard-hitter with mental highs and body stones that’ll thrill you to your very core.

These cannabis seeds need about 9 to 10 seeks to completely finish, but the results are so worth it! BlackJack easily delivers between 400 & 500 gr/m2 of total dankness if you know what you’re doing. The smoke is full-bodied, heavy as a ton of bricks and shockingly good!

BlackJack is an extra-sticky feminized cannabis seed created by the Nirvana Seeds brand. The Nirvana Seedbank hit their own jackpot when they got their hands on the original Positronics’ gene pool, but these elite breeders have also produced completely unique marijuana seeds of their own. Old or new, you’ll love your new Nirvana Seeds! Order yours now!
