Tonygreens Tortured Beans/ 2021 Karma Genetics Collaboration
Sowah Pine Tar Gush F1
Pine Tar Gush x Sour Diesel Bx4
Tonygreen’s amazing Pine Tar Gush makes a stunning return for his 2021 collaboration with Karma Genetics! TG couldn’t think of a more appropriate partner for the unique terp profiles the Pine Tar Gush inherited from her Pine Tar Kush lineage than Karmas perfectly inbred Sour Diesel Bx4. The effects of both of these strains are extraordinary. Simply put, they make you feel great proving high potency cannabis doesn’t have to put you to sleep. Expect Sowah, piney, gassy terps, and world-class resin production. Another world-class F1 bringing together perhaps 2 of the best cannabis lines in history.
Flowering Time: 63-77 days
Yield: High with dense and resin-rich flowers
Area (Indoor, Outdoor, Both): Both, please top your plants and prune lower branches for the best results
15 Regular Seeds (10 Green pheno and 5 Black pheno in separate tubes) per pack plus all Sowah packs will come with a five-pack of “Bubblehead” Headbanger x Gorilla Bubble feminized seeds!
