Sweet Tooth Auto Seeds

Outback Seed Bank presents Sweet Tooth Auto as a compact, feminised autoflower for growers who value a quick cycle, manageable size and a layered sweet flavour profile. Its ruderalis heritage allows flowering to begin according to age rather than a change in daylight hours, making planning straightforward for indoor rooms and suitable outdoor settings.

Genetics & effects

Sweet Tooth Auto is described as a Sweet Tooth × ruderalis autoflowering hybrid with an approximately 70% indica and 30% sativa balance. Catalogue figures list THC at 12–16% and CBD at 0.1–1.6%. Individual plants and finished flower can vary with phenotype, environment and handling.

The aroma and flavour may combine berry, floral, tropical and sugary notes with pepper, lavender and pine accents. Myrcene, caryophyllene, pinene and linalool are among the listed terpenes. Experiences are subjective, though some people describe the effects as initially uplifting, happy, energetic or talkative, followed by a more focused and relaxed feel. Setting, individual sensitivity and flower composition can all shape the experience.

Growing in Australia

This beginner-level autoflower is suited to hot, dry areas, temperate regions and cool locations with short growing windows. Its compact footprint can suit discreet spaces, but healthy growth still depends on strong light, suitable airflow and stable root conditions. Use an airy medium with reliable drainage and avoid keeping the root zone constantly wet.

Outdoor spring planting in Australia generally falls between September and November. Autoflowers have a limited period for vegetative growth, so minimise transplant stress and establish seedlings in their final container early. Always check the rules that apply in your state or territory before acquiring seeds or growing plants.

Indoor

Indoors, plants may reach up to 100 cm. Provide consistent lighting and enough space for air to move through the canopy. Gentle low-stress shaping early in growth may help expose more flowering sites, while heavy pruning can slow a short autoflower cycle. Monitor humidity around dense flowers to reduce mould risk.

Indoor yields are listed at up to 550 g/m² under favourable conditions. This is a reference figure rather than an assured outcome; lighting, container volume, nutrition, climate control and grower experience can make a substantial difference. Explore more autoflower seeds and feminised seeds.

Outdoor

Outdoors, Sweet Tooth Auto may remain around 90 cm and produce up to 200 g per plant in favourable conditions. Choose a sunny, sheltered position with free-draining soil or containers. In humid or rainy districts, increase spacing, inspect flowers regularly and protect plants from prolonged late-season moisture. In hotter inland areas, steady watering and a light mulch can help limit rapid drying without leaving roots waterlogged.

Harvest

The listed flowering period is approximately 6–7 weeks, though the full seed-to-harvest cycle will be longer and can vary by phenotype and conditions. For spring-planted outdoor crops, Australia’s broader harvest season is March–May, but fast autoflowers may finish earlier depending on sowing date and local weather. Assess flower maturity directly rather than relying only on a calendar. Careful drying in a dark, ventilated space helps preserve aroma, colour and the sweet profile that makes this variety a favourite among compact-auto growers.
