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

Smell-first: the cure jars open to a layered mix of ripe fruit, damp soil, and faint floral notes that sit surprisingly clean given the 20–25% THC range this cultivar regularly produces. Black Widow from Premium Cultivars is a feminized strain that finishes in 7–9 weeks and pulls 400–500 g/m² under decent indoor lighting — honest numbers for a plant that doesn't ask for much beyond consistent feeding and a reasonable VPD. It handles both indoor tents and sheltered outdoor runs in Canadian summers, though growers in shorter-season provinces like Manitoba or Alberta should start seeds early indoors and transplant once nighttime temps hold above 10°C.

The effect profile leans toward head-up clarity with a physical edge that sets in later, which makes it useful across a range of sessions. Rated moderate difficulty, it suits growers who've done a run or two and want a reliable workhorse without babysitting a fussy phenotype.
