White Widow Auto Seeds

Genetics & effects

White Widow Auto is a feminised, autoflowering hybrid presented in the Outback Seed Bank catalogue. Its lineage combines White Widow with ruderalis, producing an estimated 60% indica and 40% sativa profile. Catalogue figures place THC at approximately 15–20% and CBD at 0–0.5%, although cannabinoid content can vary with phenotype, environment and harvest timing.

The reported experience is often described as beginning with an energetic, uplifting or euphoric mood before settling into a more relaxed feeling. Some people may find it happy and sociable, while others may perceive its indica-leaning side more strongly. Effects remain subjective and can differ from person to person.

Earthy, woody and floral notes shape the expected flavour profile. Myrcene, caryophyllene and pinene are the principal listed terpenes, potentially contributing herbal depth, peppery warmth and a fresh, pine-like edge.

Growing in Australia

This beginner-friendly autoflower is suited to hot, dry and temperate Australian settings. Its ruderalis heritage means flowering is driven mainly by plant age rather than changing daylight hours. That can simplify scheduling, but stable conditions, suitable airflow and careful observation remain important.

For conventional outdoor planning in the southern hemisphere, spring planting falls from September to November, while the broader seasonal harvest period runs from March to May. Because autoflowers develop on a shorter schedule, spring-planted specimens may finish earlier than photoperiod plants. Always account for local temperature, rainfall and humidity rather than relying on the calendar alone.

Indoor

Indoors, White Widow Auto can reach up to 120 cm and may produce up to 450 g/m² under favourable conditions. These figures are reference points rather than assured outcomes. A consistent light cycle, moderate feeding and enough vertical clearance can support steady development.

• Estimated flowering: 8–9 weeks
• Indoor height: up to 120 cm
• Indoor yield: up to 450 g/m²

Its automatic life cycle leaves limited time to recover from major stress. Gentle plant handling, restrained feeding and good air movement are generally preferable. Monitor moisture around dense flowers to reduce mould risk.

Outdoor

Outdoors, plants may reach up to 180 cm and produce up to 80 g each in favourable conditions. Choose a bright position with free-draining soil and shelter from prolonged rain or severe wind. In hot, dry regions, morning watering and surface mulch can help moderate moisture swings. In temperate areas, airflow and rain protection become more important as flowers gain weight.

Harvest

Flowering is estimated at 8–9 weeks, but total seed-to-harvest time may be longer. Assess maturity from overall flower development rather than elapsed weeks alone. The broader Australian harvest season is March–May, although autoflowering plants started in spring may be ready sooner. Final height, yield, colour, aroma and cannabinoid levels will vary by conditions and phenotype.
