Quick read: 40-60% THC, 60-100cm mature height, 8-10 weeks bloom. Genetics: Northern Lights x Blueberry Auto (Blimburn Seeds). Difficulty: moderate.

Lineage: Northern Lights × Blueberry Auto from Blimburn Seeds — two indica workhorses crossed into a single autoflowering package that finishes in 8–10 weeks regardless of light schedule. That makes it a reasonable fit for Canadian growers pushing a late-season outdoor run or managing a perpetual indoor cycle without flipping rooms. THC figures from this cross land in the 40–60% range, which puts it firmly in heavy territory, so expect a couch-leaning effect rather than anything functional.

Indoors, growers report 400–500 g/m² under decent light, which is solid output for an auto. The nose skews fruity and earthy — blueberry up front, with a damp-soil finish that rounds it out. Rated moderate difficulty, so it's not a beginner's first run, but it doesn't require obsessive dialing either. Both indoor and outdoor environments work.

Best suited for experienced home growers who want a fast-finishing indica without sacrificing meaningful yield numbers.

The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.
