White Widow Autoflower Seeds

White Widow Autoflower was selected and stabilized by Lighthouse Genetics over multiple generations. White Widow is one of the most famous cannabis strains ever created — a Dutch coffeeshop legend that won the 1995 Cannabis Cup. This autoflower version delivers the same crystalline trichome coverage and balanced effects in a compact, fast-finishing plant that flowers automatically regardless of light schedule.

Genetics & Lineage

White Widow traces back to a cross of a Brazilian sativa landrace x South Indian indica, first bred by Green House Seeds in the Netherlands in 1994. The autoflower version adds ruderalis genetics to enable automatic flowering. The Brazilian parent contributes uplifting sativa energy and resin production, while the South Indian indica brings density, potency, and the signature heavy trichome coverage that gives White Widow its name — buds so frosty they appear white.

Appearance

True to the White Widow name, buds are coated in an exceptional layer of white trichomes that makes them look frosted or snow-covered. The autoflower version produces compact plants, typically 50–80 cm indoors, with dense, rock-hard buds. Colors are primarily bright green with white crystal coverage and sparse orange pistils. The overall plant structure is bushy and manageable, well-suited to small grow spaces.

Aroma & Flavor

The aroma is earthy, woody, and pungent with spicy-herbal notes and a resinous backbone. Once cured, sweeter floral and pine notes emerge. On the inhale, expect crisp earth and pine with subtle citrus zest. The exhale carries woody spice and a slightly sweet, floral finish. The heavy trichome coverage contributes to a strong, resinous smell that builds during flower. Dominant terpenes include myrcene, caryophyllene, and pinene.

Effects

White Widow Auto delivers a balanced high with THC in the 18–22% range. The onset is a burst of euphoria and energy — talkative, creative, and uplifting. As the session progresses, calming physical sensations settle in from the indica side, creating a well-rounded experience. Good for both daytime and evening use depending on the dose. The effects are reliable and consistent, which is part of why White Widow has remained popular for over 30 years.

Growing Information

White Widow Autoflower is one of the easiest strains to grow — an excellent choice for first-time growers. Plants go from seed to harvest in approximately 10–12 weeks total under 18–20 hours of daily light. Expect compact plants reaching 50–80 cm indoors, making it ideal for tent grows and small spaces. Yields range from 350–450 g/m² indoors and 60–140 g per plant outdoors. The strain is naturally resilient to mold, pests, and climate swings. No light schedule management needed — just provide consistent light, moderate nutrients, and steady airflow.
