Lineage: Critical x Northern Light Auto from Blimburn Seeds combines two workhorses of the indica world into a compact autoflower that suits both indoor tents and sheltered outdoor plots across Canada. Lab panels on this cross consistently land in the 20–25% THC range — respectable for a plant that wraps up flowering in 8–10 weeks without needing a light-schedule change. Indoors, growers report 400–500g/m² when given a decent feeding program, which is a solid return for the footprint these plants occupy at 60–100cm tall.

The aroma leans citrus-forward early in cure, then skunk and earth come through as the jars open up. Difficulty sits at moderate — you'll want some experience dialing in humidity during the final weeks, since the dense bud structure can invite moisture problems if airflow is neglected. Best suited to intermediate growers who want a fast-finishing, high-yielding indica without babysitting a photoperiod through a full Canadian season.
