Quick read: 20-25% THC, 100-180cm mature height, 9-11 weeks bloom. Genetics: Silver Widow (Kannabia Seeds). Difficulty: moderate.

Smell-first impressions from this one tend to surprise people — the skunky-floral combo reads earthier than a typical White Widow offspring, with a floral note that comes through cleanest in the final two weeks of flower. Rooted in Kannabia's Spanish breeding program, Silver Widow pushes THC into the 20–25% range while staying manageable for growers who aren't chasing a difficult project. Flowering wraps in 9–11 weeks indoors or out, and indoor runs consistently land around 400–500 g/m² when plants get adequate canopy space.

The effects sit on the relaxed-but-functional side — clear-headed enough for daytime without the edge that sometimes comes with higher-THC feminized strains. Moderate difficulty means you'll want some grow cycles under your belt, but nothing here demands expert-level intervention. Good fit for home growers who want solid, predictable output from White Widow lineage without babysitting a finicky cultivar.

Genetics & Lineage

Silver Widow traces its genetics to Silver Widow (Kannabia Seeds). This hybrid-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Kannabia Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Silver Widow delivers THC levels of 20-25%, 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 Silver Widow

Silver 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 9-11 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm 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

Silver Widow features a skunky, floral terpene profile that develops complexity throughout the flowering cycle. The complex aromatic bouquet develops fully after proper curing. 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, Silver 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 Silver Widow?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
