At 18% THC and a 7-to-9-week flower window, this one moves fast without asking much in return. Growers working both indoor and outdoor setups have pulled around 450g/m² under standard conditions, which is a respectable number for an auto that handles itself with minimal fuss.

The nose leans fruity up front, then drops into skunk and damp earth as it dries — nothing candy-coated about it. Plants stay compact, mold resistance holds up in humid conditions, and the uplifting, focus-oriented effects make it useful during the day. Good pick for first-time auto growers who want a fast turnaround without sacrificing yield or having to dial in a complicated feed schedule.
