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.

Crop King Seeds lists this at $35.10 — above the median of $30.11 across 5 listings. Pack options: 3-seed at $35.10, 5-seed at $58.50, plus larger sizes.

Smell-first: crack a jar of dried Black Widow buds and you get damp forest floor cut with a faint sweetness — earthy and clean rather than loud. That aroma carries into the effect, which leans cerebral and upbeat in the way a well-grown sativa tends to. THC lands between 14–19%, enough for a clear, functional lift without knocking newer consumers sideways.

Autoflowering genetics mean you're not managing light schedules — plants move from seed to harvest in 8–10 weeks total, indoors or out. Yields in the 450–600 g/m² range are solid for an auto, especially given how forgiving the plant is to grow. It handles beginner-level mistakes — inconsistent watering, minor nutrient swings — without throwing a fit. If you've been burned by finicky strains that demanded perfect conditions to hit acceptable numbers, this one operates with a wider margin for error. Best suited to first-time autoflower growers or anyone running a fast seasonal outdoor cycle who needs a reliable, low-drama plant.
