Blueberry Auto Seeds

Genetics & effects

Blueberry Auto is a feminised autoflowering hybrid presented in the Kiwi Seed Bank catalogue. Its reported lineage is Blueberry × Lowryder #2, although the precise family history is uncertain. The profile is approximately 80% and 20% sativa, combining classic berry character with the speed and automatic flowering of Lowryder-type genetics.

Reported THC levels range from 14–21%, while CBD may fall between 0–3%. These figures are estimates rather than guarantees, as cannabinoid content can vary with phenotype, environment and handling. Aromas and flavours may include sweet blueberry, earthy pine and touches of tropical fruit, supported by myrcene, caryophyllene and pinene.

Individual experiences differ. Some consumers describe a euphoric, happy or giggly beginning that gradually develops into a relaxed, body-oriented feeling. Increased appetite is also sometimes reported. Potency and perceived balance can vary between plants and individuals.

Growing in New Zealand

This beginner-friendly autoflower can suit several New Zealand growing regions, including temperate areas, hot and dry locations, and cooler districts with short summers. Autoflowering plants bloom according to age rather than changing daylight hours, giving growers flexibility around seasonal timing.

For outdoor cultivation, spring planting generally falls between September and November. Select a bright, sheltered position with free-draining soil and good airflow. New Zealand's changeable spring weather can bring cool nights and frequent rain, so avoid persistently damp sites. In exposed coastal areas, shelter plants from strong wind and salt-laden air.

Indoor

Indoors, Blueberry Auto may reach up to 130 cm and can produce up to 450 g/m² under favourable conditions. Its flowering phase is usually listed at 8–9 weeks, although the complete seed-to-harvest cycle may be longer. A consistent light schedule, moderate nutrition and a well-aerated root zone help support steady development.

• Use a light, free-draining growing medium.
• Allow enough vertical room for variable phenotypes.
• Maintain airflow through the canopy to reduce mould risk.
• Avoid heavy training or unnecessary stress during the short vegetative phase.

Outdoor

Outdoor plants may grow up to 180 cm and yield up to 80 g per plant in favourable settings. Actual size and productivity depend on planting date, sunlight, root space, weather and plant variation. A warm northern garden may support larger plants, while cooler southern sites can favour smaller, faster specimens.

Berry and purple colour can become more noticeable in cooler conditions, but appearance varies. Regularly inspect dense flowers after rain, particularly as autumn humidity rises. Supporting branches and keeping nearby vegetation under control can improve airflow.

Harvest

New Zealand's broader outdoor harvest season typically runs from March to May. Because Blueberry Auto follows its own age-based cycle, spring-planted specimens may finish earlier, while later starts may align with the autumn window. Judge readiness from overall flower maturity rather than the calendar alone. The listed yields, heights, cannabinoid ranges and timings are indicative; each seed can express different characteristics. For growers seeking sweet berry aromas, quick flowering and an approachable format, this could become a favourite seasonal option.
