Red Devil Auto Seeds

Genetics & effects

Presented in the Outback Seed Bank catalogue, Red Devil Auto is a feminised autoflower with a reported Afghani × Afghani Skunk lineage and unspecified autoflowering genetics. Its profile is described as approximately 80% indica and 20% sativa, with reported THC levels of 15–21% and CBD of 0–1%. As lineage and cannabinoid figures have limited supporting detail, they are best viewed as general catalogue guidance rather than fixed outcomes.

Individual experiences can differ. Some users describe the effects as initially energetic, euphoric and arousing, followed by a powerful, heavier sensation associated with its indica-leaning character. The flavour profile combines herbal, pine, earthy and nutty notes. Myrcene, pinene and caryophyllene are the principal reported terpenes, potentially contributing to its forest-like aroma and savoury depth. Its distinctive colour and bold scent may appeal to growers seeking something outside their usual favourite.

Growing in Australia

Red Devil Auto is listed as an intermediate-level option suited to hot, dry areas, temperate regions and cool locations with short summers. Autoflowering plants move through their life cycle according to age rather than a seasonal light change, which can simplify timing but leaves less opportunity to recover from early stress. Stable conditions, gentle handling and careful observation are useful throughout the cycle.

For outdoor cultivation, spring planting generally falls between September and November, while typical seasonal harvest timing is March to May. An autoflower may finish earlier depending on sowing date, local weather and phenotype. In humid districts, allow generous airflow and keep dense growth away from persistently damp surfaces to reduce the risk of mould.

Indoor

Indoors, plants are reported to reach up to 140 cm. A light, well-draining medium and a consistent environment can help maintain steady growth. Avoid abrupt changes in lighting, moisture or nutrition, particularly during the seedling stage. Low-stress canopy management may help distribute light, although substantial pruning can slow an autoflower with a limited vegetative window.

• Reported cycle: approximately 9–10 weeks under favourable conditions
• Reported yield: up to 550 g/m²
• Experience level: intermediate

These figures are estimates, and actual height, timing and output vary with phenotype, equipment and grower decisions. Explore more autoflower seeds for related catalogue options.

Outdoor

Outdoors, Red Devil Auto is reported to grow up to 190 cm, so choose a bright position with enough space for branching. Shelter can be useful where strong wind or heavy rain is common. Check moisture at root level rather than relying on surface appearance, and avoid leaving the medium saturated. In cooler, short-season regions, selecting the warmest practical part of spring may support more consistent early development.

• Reported yield: up to 650 g per plant
• Suitable climate profiles: hot and dry, temperate, or cool with a short season

Harvest

Assess maturity from the plant itself rather than the calendar alone. Aroma, flower density and natural changes in pistils and trichome appearance can provide useful indicators. Because this is an autoflower, record the germination date and monitor progress across the reported 9–10‑week cycle. Final flavour, potency, colour and yield remain dependent on phenotype and cultivation conditions.
