Smell-first: crack open a jar of Killer Kush F1 Fast Feminised and the first thing that hits is raw diesel cut with damp earth — not subtle, not sweet, just straightforward and loud. This is a Seedsman-bred indica feminized for growers who want a fast turnaround without sacrificing weight, and the numbers back that up: flowering wraps in 8–10 weeks with indoor yields landing between 500–650g/m² under good light. THC tests typically come in at 18–25%, so the potency is genuine rather than aspirational. It runs moderate in difficulty and handles both indoor and outdoor setups reasonably well, though indoors you'll have better control over that pungent odor — neighbors will notice if you're running this outside without a plan.

Best suited for growers with at least one or two cycles of experience who want a heavy-yielding, fast-finishing indica and aren't afraid of a room that smells like a fuel depot.
