About Black Widow Feminized
The genetic expression of Black Widow, a 86/14 indica, varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: a compact, bushy plant with broad fan leaves and golf-ball-dense flowers that pack on weight in the final two weeks. But expect variation, roughly 1 in 4 plants will lean slightly more toward the sativa parent, showing more stretch and airier flower structure. THC testing at 27% across phenotypes, with Linalool consistently dominant.
Genetic Expression in the Grow Room
The dominant phenotype, which appears in roughly 70-75% of seeds, produces a compact, symmetrical plant with broad internodes and heavy lateral branching. Fan leaves are wide and dark green, typical of the indica heritage. Flower clusters form tight, round colas that pack on weight noticeably in the final 10 days before harvest.
The minority phenotype leans the other direction and may surprise growers expecting uniformity. Flowering completes in 9-11 weeks across phenotypes. Yield: 350-450g/m² indoor, 500-700g/plant outdoor. Height: Tall (4-5 ft). Rated intermediate, the phenotype variation adds a layer of interest without adding significant difficulty. Growing from feminized seeds.
What Users Report
Black Widow at 27% THC produces euphoric, creative, calm sensations that users consistently describe as physically comforting without being immobilizing at moderate doses. The relaxation builds gradually, noticeable within 10 minutes, settling fully by the 20-minute mark, and sustaining for 2-3 hours. The Linalool/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other indicas at similar THC levels.
Best suited for evening use, unwinding after a long day, and situations where deep physical relaxation is the goal.
Terpene Profile
Dominant terpenes: Linalool (primary), Myrcene (secondary), Caryophyllene (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385°F) and combustion, though lower temperatures preserve the myrcene top notes that combustion destroys.
Who Should Grow Black Widow
This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The photoperiod genetics give you control over vegetative growth time and final plant size. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 9-11 weeks flowering period to their frost-free window.
