Auto Blueberry 420
Also known as: Blueberry Auto, Auto Blueberry, Blueberry 420 Auto
Overview
Auto Blueberry 420 is an indica-dominant autoflowering cannabis strain that represents a modern adaptation of the legendary Blueberry genetics originally developed by DJ Short in the 1970s. This strain combines the classic Blueberry lineage with ruderalis genetics to create an autoflowering variety that maintains the distinctive characteristics of its photoperiod ancestor while offering faster growing cycles and simplified cultivation. The strain is created through crossing traditional Blueberry genetics with Canadian Ruderalis and Light of Jah (a Jack Herer x Afghani hybrid), resulting in a genetic profile that typically expresses as 65% indica to 35% sativa, though some phenotypes show up to 80% indica dominance.
Auto Blueberry 420 develops into a compact, bushy plant that stays relatively small, typically reaching heights of 70-110cm indoors and up to 90cm outdoors, making it ideal for discreet cultivation. The strain produces dense, resinous buds that display striking visual appeal with bright green coloration often accompanied by purple, pink, yellow, and red hues throughout the flowers and surrounding foliage. The buds are completely covered in a thick layer of trichomes, giving them a frosty appearance and sticky texture. The plant's structure is characterized by wide fan leaves, thick stems, and sturdy branches that develop rock-solid buds from top to bottom.

Growing Information
Auto Blueberry 420 is considered beginner-friendly with easy cultivation requirements. The strain has a fast flowering cycle of 7-10 weeks from seed to harvest (49-65 days total). Indoor yields range from 350-500g/m² with plants staying compact at 70-110cm tall. Outdoor cultivation produces 150-450g per plant with heights up to 90cm. The strain thrives in temperatures between 65-80°F (18-27°C) and prefers moderate humidity levels (55-60% during vegetative stage, reducing to 40% during flowering). It shows good resistance to pests and diseases, performs well in soil, coco, or hydroponic systems, and benefits from light defoliation due to its bushy indica structure. The strain adapts well to various growing environments including SOG (Sea of Green) setups.
