White WidowStrain, Effects, Genetics, Grow Guide & Where to Buy
Few cultivars carry the cult following White Widow has built across the US grow community , and the appeal is easy to explain. It is a balanced hybrid (40% indica / 60% sativa) testing at roughly 26% THC, with a flowering window of 50-55 days (harvest 70-85 days after germination) as an autoflower. What follows is a complete reference: terpene-led effects, genetic background, indoor and outdoor grow guidance, and the fastest way to get White Widow seeds shipped to your state.

White WidowEffects & Experience
White Widow is best known for euphoric, relaxed, uplifted. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting, what you feel in the first 20 minutes is what you have for the next 90.
Growing White Widow
Growing White Widow fits cooler climates where photoperiod strains struggle to finish before frost, autoflower timing is calendar-driven, not daylight-driven. White Widow runs on an 18/6 light schedule from seed to harvest, autoflower genetics ignore photoperiod, so there is no flip and no light-cycle change. Indoor yields land around 14 to 16 oz/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 7 to 8 oz/plant. Expected plant height is 1 to 3 feet, with intermediate cultivation difficulty. Practical tips that move the needle: defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
White WidowLineage & Genetics
Lineage: Brazilian Sativa x South Indian Indica. That parental cross is the reason White Widow expresses the way it does, manageable height, balanced bud structure, and a flexible response to training.
