Eight growers logged consistent harvests with this Blimburn auto across both tent and outdoor runs — 400–500g/m² in 8–10 weeks from flip to chop, no light schedule management required. That output comes attached to a 20–25% THC ceiling, which puts it firmly in the heavy-hitter category for an autoflower. The flavor profile skews citrus-forward on the inhale with a skunky, damp-earth finish that lingers — classic indica territory, nothing tropical or candy-like. Critical x Northern Light Auto tends to stay compact (think 60–100cm), so it fits comfortably in low-clearance spaces without much canopy work. Moderate difficulty means newer growers won't get punished for small mistakes, but it rewards anyone who dials in VPD and feeds — yields tighten up noticeably when plants get what they need. Good pick for growers who want a dependable, resinous indica auto without babysitting a photoperiod through a full season.
