Red Devil Auto Seeds

Genetics & effects

Presented in the Kiwi Seed Bank catalogue, Red Devil Auto is an indica-dominant autoflower with a reported 80% indica and 20% sativa profile. Its lineage is described as Afghani crossed with Afghani Skunk, alongside unspecified autoflowering genetics. As the available lineage information is limited, these details are best viewed as a guide rather than a complete genetic record.

Reported THC levels range from 15% to 21%, with CBD listed between 0% and 1%. Individual experiences can vary, but some consumers describe the effects as powerful, euphoric and physically engaging, sometimes accompanied by an energetic or aroused feeling. The aromatic profile leans herbal, earthy and nutty, with fresh pine notes. Myrcene, pinene and caryophyllene are the principal reported terpenes.

Growing in New Zealand

Red Devil Auto is considered an intermediate-level option. Its automatic flowering pattern means development is guided mainly by plant maturity rather than changing daylight hours. In New Zealand, spring planting runs from September to November. A warm, bright position during this period gives plants time to establish before the more settled part of summer.

The variety is associated with hot, dry, temperate and cool short-season settings, although local conditions still matter. Good airflow, free-draining growing media and shelter from persistent rain can reduce the risk of mould. Autoflowers generally have limited time to recover from major stress, so steady care is preferable to frequent changes.

Indoor

Indoors, plants may reach up to 140 cm. Allow enough vertical room for lighting clearance, containers and airflow around the canopy. A consistent light schedule, stable temperatures and moderate feeding suit the fast lifecycle. Gentle training early in growth may help manage height, but heavy pruning can slow an autoflower at a key stage.

Reported indoor yields are up to 550 g/m² under favourable conditions. This is a catalogue figure rather than an assured outcome; lighting, plant health, environment, experience and available space all influence final performance.

Outdoor

Outdoors, Red Devil Auto may grow up to 190 cm in a sunny, protected position. Choose a site with direct light, drainage and airflow, while accounting for strong New Zealand winds and rapid weather changes. In wetter areas, spacing plants well and keeping dense growth away from damp surfaces can help reduce moisture build-up.

Reported outdoor production is up to 650 g per plant in favourable conditions. Container size, sunlight, temperature, exposure and grower technique can all affect plant size and output. Discreet positioning may also be important where a taller specimen would be noticeable.

Harvest

The listed flowering period is approximately 9–10 weeks, though the full seed-to-harvest cycle may be longer. For seasonal New Zealand gardens, the main outdoor harvest period is March to May. Because this is an autoflower, timing can differ according to the sowing date and local climate.

Check flower maturity directly rather than relying only on the calendar. Aroma may deepen towards earthy pine and nutty notes, while natural colour changes can become more visible late in the cycle. Dry harvested flowers slowly in a dark, ventilated space with controlled humidity to preserve their characteristic profile.
