White Widow Auto Seeds

Genetics & effects

White Widow Auto combines White Widow genetics with ruderalis to create an autoflowering hybrid that moves into bloom according to age rather than changes in daylight. Its profile is approximately 60% indica and 40% sativa, offering a practical balance of compact growth and lively hybrid qualities.

THC content is listed at around 15–20%, while CBD is listed below 0.5%. These figures are useful guides rather than fixed outcomes, as cannabinoid levels can vary with phenotype and growing conditions. Individual experiences may also differ. Some users describe the effects as initially uplifting, energetic, euphoric or happy, followed by a more relaxed feeling. The aroma and flavour profile blends earthy, floral and woody notes, with myrcene, caryophyllene and pinene among the associated terpenes.

Growing in New Zealand

Presented in the Kiwi Seed Bank catalogue, White Widow Auto is considered suitable for beginners and can adapt to temperate or hot, dry conditions. In New Zealand, spring planting generally falls between September and November. Autoflowering plants do not rely on shortening days, so timing can be flexible where temperatures and light remain suitable.

Choose a bright, sheltered location with free-draining soil or growing media. Consistent airflow and sensible spacing can reduce the risk of mould during humid periods. Because autoflowers have a limited vegetative window, avoid unnecessary disturbance and make environmental changes gradually.

Indoor

Indoors, plants may reach up to approximately 120 cm. A stable light schedule, moderate feeding and good air movement support even development. Gentle, early canopy shaping may help light reach more flowering sites, but heavy pruning can slow a fast lifecycle.

• Indicative flowering period: around 8–9 weeks
• Indicative indoor yield: up to 450 g/m²
• Maintain airflow around dense flowers
• Allow the growing medium to drain freely

Yield and timing figures are estimates, not promises. Container size, light intensity, temperature, nutrition and phenotype all influence the final result.

Outdoor

Outdoors, White Widow Auto may grow up to approximately 180 cm in favourable conditions, although many plants remain smaller. Indicative production is up to 80 g per plant. A warm position with direct sun is ideal, while shelter from strong wind and prolonged rain can help preserve flower quality.

For spring starts, use the milder part of September–November and avoid exposing young plants to cold nights. Later sowings may suit warmer northern areas, while cooler southern locations often benefit from an earlier, sheltered start. Check plants regularly after rain and keep foliage from resting against damp surfaces.

Harvest

New Zealand’s broader outdoor harvest season is typically March–May, though autoflowering plants may finish earlier depending on their sowing date. The stated 8–9 week flowering window should be counted as an estimate once flowering is established, rather than as a precise full-cycle calendar.

Assess maturity by observing flower development, resin coverage and the colour of the trichomes. Harvest in dry weather where possible, then dry branches slowly in a dark, ventilated space. Stable airflow and regular inspection help reduce the risk of excess moisture affecting aroma, flavour or finish.
