Red Devil Auto brings classic Afghan depth to a fast, easy-growing autoflower. Expect resin-rich buds, a crisp herbal-and-pine profile, and a deeply relaxing finish. With a compact build and a quick 6–8-week life cycle, it’s a compelling pick for growers who want rich character without a long wait.

Our breeders developed Red Devil Auto from Afghani, Afghani Skunk, and Ruderalis genetics. This 75% indica, 25% sativa hybrid carries the earthy heritage of its Afghan roots, with Ruderalis bringing automatic flowering and a resilient growth pattern suited to varied conditions.

The aroma opens with fresh pine, then settles into warm herbs and earthy Afghan notes. Each inhale brings a clean, forest-like edge, while the flavor stays smooth and mellow. Dense buds shine with a crystalline coat of resin.

With THC levels of 12–16%, Red Devil Auto delivers a comforting, medium-strength experience. Relaxed, sleepy, and euphoric effects make it a natural evening choice. A gentle lift in mood and focus rounds out its soothing body feel.

Alpha-pinene and beta-pinene add the strain’s bright pine character. Myrcene lends an earthy, grounding note, while linalool and terpineol deepen the floral-herbal aroma. Its calming profile suits slow evenings and quiet downtime. The resin-rich flowers also make an appealing option for concentrates.

These autoflowering seeds flower automatically, without a change in light schedule. Red Devil Auto can complete its life cycle in 6–8 weeks, with full seed-to-harvest timing depending on conditions. Germination is guaranteed, so you can start your grow with confidence.

Red Devil Auto is a beginner-friendly choice with a hardy, manageable structure. Start seeds in a quality, well-aerated medium such as coco, peat, or a suitable soil blend. Keep young plants evenly watered and provide balanced nutrition as they develop. Indoors, an 18/6 or 20/4 light schedule supports steady growth; outdoors, choose a sunny, warm location.

Plants can reach around 4.9 feet (1.5 m), with a strong main stem and productive side branches. Maintain good airflow and keep an eye out for pests. Aim for temperatures around 70–80°F (21–27°C), with lower humidity as flowering progresses. Consistent care helps protect the plant’s flavor and resin production.

Harvest arrives quickly, making Red Devil Auto a practical choice for successive grows throughout the season. Indoor yields range from 300–450 g/m² (0.98–1.47 oz/ft²), while outdoor plants can produce 400–600 g (14.11–21.16 oz) each under favorable conditions. Expect dense, trichome-coated flowers with a bold herbal-pine finish.
