About White Widow Auto
White Widow is a 50/40 hybrid testing at 26% THC with a caryophyllene-dominant terpene profile. At a practical level, this means a plant that offers moderate stretch with balanced branching that responds well to training, finishing in 8-10 weeks. The Caryophyllene/Myrcene combination shapes both the aromatic profile and the effect character β this is not a one-dimensional strain.
Growing Parameters
Flowering time: 8-10 weeks from flip. Indoor yield at 600+ PPFD: 350-450g/mΒ². Outdoor in full sun with 5+ gallon containers: 500-700g/plant. Plant height indoors after training: Tall (4-5 ft). Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Caryophyllene production peaks when day/night temperature differential exceeds 10Β°F in the final two weeks β growers who drop nighttime temps to 62-65Β°F during this window report stronger aromatic development.
This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.
What Users Report
White Widow at 26% THC produces euphoric, relaxed, uplifted sensations that users consistently describe as versatile enough to serve different purposes depending on dose and setting. Lower doses lean more cerebral and functional. Higher doses bring the body effect forward. The Caryophyllene/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other hybrids at similar THC levels.
Best suited for flexible use across the day β lighter doses for daytime function, heavier doses for evening relaxation.
Terpene Profile
Dominant terpenes: Caryophyllene (primary), Myrcene (secondary), Humulene (tertiary). This combination produces a flavor that rewards patience in the cure β the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.
Who Should Grow White Widow
This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process β no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.
