The specs in one line: 18-25% THC, <1% CBD, 8-10 weeks flowering, 400-550g/m² reported. Best indoor or outdoor. moderate grow.

Lineage: RS11 (Rainbow Chip x Sunset Sherbet) crossed with Banana OG, two cultivars that have built serious reputations on the North American market over the past decade. That pairing pushes THC testing into the 18–25% range while keeping CBD negligible, so expect a potent, head-forward experience that settles into a body effect over time. Indoors, growers are logging 400–550 g/m² after an 8–10 week flower — solid numbers without needing to baby the plants. The terpene profile leans fruity up front with a fuel note underneath that sharpens as buds dry down. Feminized seeds mean no males to pull, which simplifies canopy management whether you're running a tent or a dedicated indoor room. Difficulty sits at moderate, so first-time growers can manage it, though anyone who's dialled in their VPD and feed schedule will see the upper end of that yield range more consistently.

Best suited to intermediate growers who want a high-THC strain with straightforward feminized genetics and don't need to chase a specialty terpene profile.
