Blueberry Auto Seeds

Genetics & effects

Blueberry Auto is a feminised autoflowering hybrid listed as Blueberry × Lowryder #2, although details of the wider lineage are uncertain. Its profile is approximately 80% indica and 20% sativa, combining classic berry character with the convenient flowering trigger associated with autoflower genetics.

THC is listed at 14–21%, while CBD may range from 0–3%. Individual experiences vary, but some adults describe the effects as initially euphoric, happy or giggly before shifting towards a more relaxed, settled feeling. A noticeable appetite is another commonly reported subjective experience. The flavour brings together sweet blueberry, earthy pine and light tropical notes, with myrcene, caryophyllene and pinene among the listed terpenes.

Growing in Australia

This beginner-friendly cultivar can suit hot, dry regions, temperate areas and cool districts with shorter summers. As an autoflower, it progresses according to age rather than a changing light cycle. Feminised seeds are intended to produce female plants, although natural variation remains possible.

For outdoor growing in Australia, spring planting generally falls between September and November. Select timing according to local temperatures, daylight and rainfall. Strong airflow and protection from prolonged rain can reduce the risk of mould, particularly as flowers become dense. Always check the rules that apply in your state or territory before germinating seeds.

Indoor

Indoors, Blueberry Auto can reach up to 130 cm. Its automatic life cycle is useful where a straightforward schedule is the favourite approach, but steady conditions remain important. Use a free-draining medium and avoid keeping the root zone constantly wet. Gentle plant shaping early in growth may help open the canopy, while heavy stress late in the short cycle may slow development.

• Flowering period: approximately 8–9 weeks
• Indoor height: up to 130 cm
• Indicative indoor yield: up to 450 g/m²

Flower colour may develop from green into blue or purple tones under suitable conditions, though expression depends on the individual plant and environment.

Outdoor

Outdoors, plants may reach up to 180 cm where warmth, root space and light are ample. In cooler or damp locations, choose a sunny, ventilated position and monitor late-season humidity. In hot, dry areas, mulch can help moderate moisture swings, but keep it clear of the main stem.

• Outdoor height: up to 180 cm
• Indicative outdoor yield: up to 80 g per plant
• Suitable climates: hot and dry, temperate, or cool with a short season

Harvest

Australia’s traditional outdoor harvest period runs from March to May. However, spring-planted autoflowers may finish earlier because their cycle is based on age, so assess each plant rather than relying only on the calendar. The stated 8–9 week flowering period is an estimate, and total time from germination can vary with conditions. Yield, height, potency, flavour and colour are indicative traits rather than assured outcomes.
