Smell-first: crack a jar of cured Schoolyard Crush and the room shifts — ripe citrus peel, something candy-sweet underneath, and a clean finish that doesn't drag on. This is a Mephisto Genetics autoflower bred to stay manageable (60–100 cm) while still pulling 400–500 g/m² in 8–10 weeks from seed, which is a realistic turnaround whether you're running a tent in a Toronto basement or an outdoor plot in the Okanagan. THC lands consistently in the 20–25% range, so effects lean toward heady and euphoric without needing a PhD in cultivation to get there — Mephisto rates it easy across both indoor and outdoor environments.

The citrus-and-sweet terpene profile makes trimming day the best part of the run. Good pick for newer growers who want a high-yielding auto without babysitting a finicky phenotype through a short Canadian season.
