The specs in one line: 18-24% THC, <1% CBD, 8-10 weeks flowering, 400-500g/m² reported. Best indoor or outdoor. moderate grow.

Lineage: Dutch Passion's original White Widow, one of the few strains that has held its ground in seed catalogues since the 1990s without needing a rebrand. These feminized seeds run 8–10 weeks to flower and pull 400–500 g/m² indoors under decent light — numbers that have stayed consistent across decades of grows. THC tests typically land in the 18–24% range, which is strong without being cartoonish about it. The nose is pine-forward with a damp, earthy base — nothing tropical, nothing candy — just the resinous, forest-floor profile that made the strain famous in the first place.

Difficulty sits at moderate, so first-time growers can manage it, though a bit of training (LST or a light topping) will help fill the canopy and push yields toward the upper end. Works well indoors or out, and Canadian growers in zones with a reliable summer should have no trouble finishing it outdoors before the first frost.

A solid pick for growers who want a proven, resin-heavy variety without chasing hype.

Effects & Experience

Users report primarily euphoric and relaxed effects, making this strain ideal for evening use and unwinding after a long day.

With THC levels reaching 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

White Widow delivers THC levels of 18-24%, 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 moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m². Plants typically reach 100-170cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

White Widow features a pine, earthy terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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.

Who Should Grow White Widow?
