Lineage: White Widow Auto traces back to Green House Seeds' original White Widow cross — Brazilian sativa and South Indian indica — rebuilt here into an autoflowering format that finishes in 9–10 weeks from seed without any light-schedule management. THC runs 16–20%, which lands in a genuinely satisfying range without tipping into the anxiety territory some high-20s strains can cause. Indoors you're looking at 400–550g/m² under decent light, and the strain handles both indoor and outdoor environments without much fuss.

The effect moves in two phases: a body-settling wave early, then a shift toward something more clear-headed and active — consistent with the sativa side of the original genetics reasserting itself. Flavor profile is floral and earthy, nothing showy, but clean and pleasant through a dry herb vaporizer. Difficulty is rated easy, which holds up — this is a reliable first autoflower for newer growers who want a well-documented genetic history behind their grow.

Genetics & Lineage

White Widow Auto traces its genetics to White Widow Auto (Green House Seeds genetics). This indica-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Greenhouse Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

White Widow Auto 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing White Widow Auto

White Widow Auto 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 9-10 weeks total with yields of 400-550g/m2. Plants typically reach 60-120cm 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 40-50% 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 Auto features a floral, earthy 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, White Widow Auto 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 Auto?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
