Granddaddy Purple Autoflower Strain Overview
Granddaddy Purple Autoflower is an indica-dominant hybrid autoflowering version of the legendary Granddaddy Purple strain, first created by Ken Estes in California in 2003. This strain combines the genetics of Purple Urkle (Afghan x Skunk) and Big Bud Auto with ruderalis genetics to create an autoflowering variant. The strain features a genetic composition of approximately 75% indica, 20% sativa, and 5% ruderalis, inheriting the signature purple coloration and grape-berry aroma from its photoperiod parent. GDP Auto is renowned for its striking visual appeal, displaying deep purple hues contrasted by bright orange pistils and a generous coating of white crystal trichomes. The buds are dense and compact with a complex aroma profile featuring prominent notes of sweet grapes, berries, blueberry, and pine, undercut by herbal and earthy undertones. This strain has gained popularity for its manageable cultivation requirements, making it suitable for both novice and experienced growers, with a complete lifecycle of 10-12 weeks from seed to harvest.

Granddaddy Purple Autoflower Strain Growing Information
Granddaddy Purple Autoflower is considered easy to moderately easy to grow, making it suitable for beginners. The strain has a complete lifecycle of 10-12 weeks from seed to harvest with a flowering period of 8-9 weeks. Indoor plants typically reach heights of 70-140cm and can yield 375-450g/m² under optimal conditions. Outdoor specimens can grow 80-150cm tall and produce 70-160g per plant. The strain thrives in both indoor and outdoor environments, preferring Mediterranean climates with temperatures between 70-85°F (21-29°C). Plants develop a compact, bushy structure typical of indica genetics and are relatively resilient to pests and diseases. To enhance the characteristic purple coloration, growers can expose plants to cooler nighttime temperatures (below 60°F) during late flowering. Humidity should be maintained around 40-50% during bloom to prevent mold issues with the dense buds.
