Crop King Seeds runs this as a sativa autoflower line — 14-19% THC lab range, earthy/sweet-dominant terps, 8-10 weeks total from flip.

Lineage: Black Widow Auto traces back to Crop King Seeds' sativa-dominant work, and the numbers make a reasonable case on their own — 14–19% THC with a full seed-to-harvest window of just 8–10 weeks. That's a quick turnaround for a sativa-leaning plant, and the 450–600 g/m² potential gives indoor growers something worth planning around.

The earthy, sweet profile is understated rather than loud, sitting comfortably on the exhale without demanding attention. Because it's an autoflower rated easy difficulty, it adapts to both indoor tents and outdoor plots — useful in shorter Canadian summers where photoperiod strains often run out of season before they're ready. Training is optional; the plant handles benign neglect better than most.

A solid pick for newer growers or anyone running a spare tent who wants a no-fuss sativa-type without babysitting a long flowering schedule.
