Blueberry Seeds & Genetics
Genetics: Afghani x Thai x Purple Thai | Breeder: DJ Short | Type: Indica-dominant Hybrid
Blueberry was developed by the legendary DJ Short through a cross of Afghani, Thai and Purple Thai genetics over many years of selective breeding. It won the High Times Cannabis Cup in 2000. Seeds are available feminised from DJ Short Seeds and licensed breeders. For growing basics, visit our beginner cannabis growing guide.
Indoor vs Outdoor Growing Blueberry
Blueberry suits indoor growing well due to its compact indica structure. Maintain temperatures at 20-24C to encourage purple and blue colour expression. See our training techniques guide for LST methods. Outdoors, Blueberry is stunning in autumn when cool nights trigger vivid colour changes. It suits temperate and cooler climates, finishing by early October. Our outdoor growing guide covers cold-climate considerations.
Nutrients & Feeding for Blueberry
Blueberry is sensitive to overfeeding - start at 50-75% of recommended nutrient doses and increase gradually. Nitrogen-dominant in veg at EC 1.0-1.4. Switch to bloom formula at first signs of flowering. Benefits greatly from organic soil grows. Flush 10-14 days before harvest. Full guidance in our nutrients guide.
Common Problems & Solutions
Overfeeding is the most common mistake - nutrient burn appears quickly. Some phenotypes show slow early growth - be patient. Moderate mould resistance; maintain humidity below 50% in flowering. Ensure oscillating fan airflow through the compact canopy.
Harvest, Drying & Curing Blueberry
Harvest when 70-80% of trichomes are milky white with 20-25% amber for balanced relaxing effect. Dry at cool temperatures 16-20C to preserve delicate terpenes. Cure minimum 4-6 weeks in glass jars - flavour improves dramatically with extended curing. Full process in our harvest guide.
