Quick read: 18-25% THC, 100-170cm mature height, 8-10 weeks bloom. Genetics: Dirty Banana Gen 1 Fast (Seedsman genetics). Difficulty: moderate.

Smell-first: crack a cured jar of this one and the room fills with ripe banana layered over damp forest floor — fruity up front, earthy on the finish, no chemical sharpness. Dirty Banana Gen 1 Fast sits at 18–25% THC depending on how well you push the canopy, and the "Fast" designation is real — most runs wrap up between 8 and 10 weeks of flower, which matters if you're squeezing an outdoor season in a shorter Canadian climate window. Indoor yields land in the 400–550 g/m² range when the plant gets proper light intensity and a stable feed schedule; dial those down and you'll feel it at harvest. Seedsman rates it moderate difficulty, so first-timers can manage but shouldn't skip the research on humidity control during late flower — the dense structure holds moisture.

Best suited to growers who want a quicker turnaround without sacrificing meaningful potency numbers.
