From the lab panel — 20-25% THC, <1% CBD. From Canadian grower reports — 400-500g/m2 yield, fruity/floral dominant in cured flower. easy grow.

Lineage: Big PUNch Auto comes straight from Mephisto Genetics, a breeder known for producing autoflowers that actually finish when the calendar says they will. That consistency shows up here — expect harvest somewhere between week 8 and 10 from sprout, with canopy heights that stay manageable indoors or in a Canadian backyard without much intervention.

THC tests in the 20–25% range put this well above the midpoint for autos, and indoor growers pulling 400–500 g/m² under a decent light setup will find those numbers credible rather than aspirational. The fruity and floral profile is present in both the fresh cut and the cure, not just the marketing copy. Rated easy, it tolerates the kinds of watering and VPD miscalculations that derail trickier cultivars. A solid pick for first-time autoflower growers who want a genuinely strong result without a steep learning curve.
