Genetics & effects

Critical Auto is a feminised autoflower described as a cross of Big Bud × Skunk #1 × ruderalis. Its profile is approximately 70% indica and 30% sativa. Because it flowers according to age rather than changing daylight hours, it offers a practical option for growers seeking compact plants and a relatively short flowering phase.

THC is listed at 15–20%, with CBD at 0–0.5%. Individual experiences can vary, but users may describe the effects as initially uplifting, euphoric, creative or giggly, followed by a calmer, more relaxed and sometimes sleepy feeling. Increased appetite may also be noticed. The aromatic profile combines sweet and fruity notes with lemon and woody accents, supported by myrcene, limonene and caryophyllene.

Growing in New Zealand

Critical Auto is considered suitable for beginners and can adapt to hot, dry regions, temperate areas and cooler locations with short summers. In New Zealand, outdoor spring planting generally runs from September to November. Choose the warmest, brightest period available locally, as regional conditions differ considerably from Northland to the lower South Island.

Autoflowers have limited time to recover from stress, so steady conditions are preferable to major changes. Use a light, free-draining growing medium, avoid unnecessary transplanting and keep watering measured. Good airflow and shelter from prolonged rain can reduce the risk of mould, especially in humid districts. Browse more autoflower seeds for other compact options.

Indoor

Indoors, Critical Auto may reach up to 65 cm, making it useful where vertical space is limited. A consistent light schedule and stable environment can support even development. Gentle canopy guidance early in growth may help expose more flowering sites, but heavy pruning is best avoided once flowering is established.

Indoor yield is listed at up to 450 g/m² under favourable conditions. This figure is an indication rather than a promise, as lighting, container size, airflow, plant care and phenotype all affect the final amount. Its compact stature and straightforward growth pattern may suit a first autoflower project.

Outdoor

Outdoor plants may grow up to 110 cm and produce up to 200 g per plant in favourable conditions. Select a sunny, discreet position with good drainage and protection from strong winds. In cooler or wetter areas, movable containers can make it easier to use sheltered spots during poor weather.

Although autoflowers do not rely on shorter days to begin flowering, warmth and strong sunlight still influence growth. Seeds started during September–November may finish before the conventional autumn harvest period, depending on sowing date, weather and phenotype.

Harvest

The listed flowering time is approximately 8–9 weeks. This refers to flowering rather than a guaranteed seed-to-harvest cycle, so allow additional time for early growth. New Zealand’s main outdoor harvest season is March–May, though fast autoflowers may be ready earlier. Check flower maturity directly rather than relying only on the calendar. Final height, timing, colour, aroma and yield can vary between plants and environments.
