From the lab panel — 16-20% THC, <1% CBD. From Canadian grower reports — 500-700g/m² yield, citrus/earthy dominant in cured flower. easy grow.

Lineage: Brazilian sativa landrace crossed with a South Indian indica — that pairing is where White Widow actually comes from, and Sensi Seeds has held those original breeding records longer than most Canadian growers have been growing. The feminized version runs 7–9 weeks to flower and routinely pulls 500–700 g/m² indoors, which is a wide enough window to work with whether you're running a tight 3×3 or a full tent. THC sits at 16–20%, so the effect is real without being a liability. The nose leans into pine and damp earth early in cure, with a faint citrus edge that sharpens as the trichome frost settles — and the frost is the visual tell that separates this plant from the knockoffs that borrowed the name over the last two decades.

Rated easy difficulty and suited to both indoor and outdoor environments, this is a dependable first feminized grow for someone stepping up from autoflowers.

THC Level & Potency

White Widow delivers THC levels of 16-20%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing White Widow

White Widow is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 7-9 weeks with yields of 500-700g/m². Plants typically reach 100-180cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

White Widow features a citrus, earthy, pine, floral terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, White Widow is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
