Black Jack

Never a Bust!

Sweet Seeds

Like all good girls, Black Jack gets her name from her parents. When Sweet Seeds crossed Black Domina with their finest Jack Herer, the resulting mixed hybrid had an intense, but tantalizing haze aroma. She’s a sticky, hairy beast who grows up short and fat, but play your cards right & this girl will keep on dealing hand after green hand. Try your luck today!

Product Details

This Nug Factory Guarantees You’ll Never Fold Early!

This Black Jack Strain is, above all else, extremely productive - although whether or not you will be after indulging in her dank, sticky nugs is debatable.

Inside, she’ll crank out between 500 and 600 grams. Take her outdoors and expect up to a full 700.

  • Consistently brings a very high yield
  • One of the most potent mixed hybrid strains ever created
  • Sticky and highly resinous, great for hash

Not only is her yield generous, but the mixed body/head blast that Black Jack Seeds deal out lasts and lasts. She’ll only keep you waiting for about nine weeks indoors, but out in the sun is where she really shines.

Go Gorilla! With the lowest prices and fastest delivery times, why would you even consider another beast in the jungle? This is the best place, bar none, to buy premium marijuana seeds!
