Durban Poison Auto Seeds

Genetics & effects

Durban Poison Auto is a feminised autoflower created from Durban Poison and ruderalis genetics. Its profile is approximately 70% sativa and 30% indica, pairing the lively character associated with Durban Poison with a growth cycle that does not depend on changing daylight hours. Outback Seed Bank presents this variety for growers seeking an energetic, upright auto with moderate cultivation demands.

THC content is listed at 15–21%, with CBD at 0–0.5%. Individual experiences can vary, but users commonly describe the subjective effects as uplifting, euphoric, creative and focused, often with an energetic edge. The flavour profile may combine sweet citrus and spice over earthy pine. Terpinolene, myrcene and pinene are prominent parts of its aromatic profile.

Growing in Australia

This intermediate-level variety can suit hot, dry, temperate and cool regions with shorter summers. As an autoflower, it begins flowering according to maturity rather than a strict light schedule. That makes timing comparatively flexible, although strong light, stable conditions and sensible moisture management remain important.

For Australian seasonal planning, spring planting falls from September to November, while the traditional outdoor harvest window is March to May. Durban Poison Auto may finish earlier than that autumn window when started in spring because its lifecycle is driven by age. Local temperature, latitude, container size and plant health can all influence timing and final size.

Indoor

Indoors, plants may reach up to 140 cm, so allow enough vertical room for their sativa-leaning stretch. Gentle canopy guidance early in growth can help distribute light without placing unnecessary stress on the plant. Good airflow is particularly useful around dense growth, while steady environmental settings can reduce the risk of mould and stalled development.

• Flowering: approximately 8–9 weeks
• Indoor yield: up to 400 g/m²
• Indoor height: up to 140 cm
• Seed type: feminised autoflower

Outdoor

Outdoors, Durban Poison Auto may grow to 180 cm in favourable conditions and can produce up to 150 g per plant. Choose a position with ample direct sun and moving air. In hot, dry areas, monitor how quickly containers lose moisture. In temperate or cool, short-season districts, a bright and sheltered location can support consistent progress.

A free-draining medium is preferable, especially where seasonal rain or humidity is common. Avoid leaving roots continually wet, and inspect flowers as they develop so that excess moisture or signs of mould can be addressed promptly. The plant’s potential size makes discreet spacing and wind protection worth considering.

Harvest

Use flower maturity rather than a fixed calendar date as the main harvest guide. Aroma often becomes sweeter and more pronounced late in flowering, with earthy, spicy, pine and citrus notes coming forward. Reported height, flowering time and yields are reference points rather than assurances; phenotype, weather, lighting and grower experience can produce meaningful variation.
