Grand Daddy Purple Autoflower
Also known as: GDP Auto, Granddaddy Purple Auto, GDP Autoflower
What is the Grand Daddy Purple Autoflower strain?
Grand Daddy Purple Autoflower is a indica cannabis strain with up to 22.0% THC, known for its relaxed effects and berry and earthy flavor profile.
Grand Daddy Purple Autoflower is an autoflowering variant of the classic Grand Daddy Purple (GDP) strain, developed to combine the signature characteristics of the original with the convenience of autoflowering genetics. This strain was created by crossing the original Grand Daddy Purple (itself a cross of Purple Urkle and Big Bud) with autoflowering ruderalis genetics. The result is a compact, fast-flowering plant that maintains the distinctive purple coloration, dense bud structure, and potent effects of its photoperiod parent while automatically transitioning from vegetative growth to flowering based on age rather than light cycles.
The strain is characterized by its striking visual appearance, with deep purple hues often dominating the foliage and buds, complemented by vibrant orange pistils and a thick coating of frosty trichomes. The buds are typically dense and resinous, emitting a complex aroma that blends sweet grape, berry, and earthy notes with subtle floral undertones. Grand Daddy Purple Autoflower is particularly noted for its relatively short life cycle, typically completing its growth from seed to harvest in 8-10 weeks, making it appealing to growers seeking quick turnaround times.
As an autoflowering variety, this strain offers practical advantages for cultivation, including resilience to light schedule fluctuations and suitability for continuous harvest setups. However, it generally produces smaller yields compared to photoperiod GDP plants and offers less control over vegetative growth timing. The strain has gained popularity among both home growers and commercial producers seeking reliable, consistent results with minimal cultivation expertise required.

How do you grow Grand Daddy Purple Autoflower?
Grand Daddy Purple Autoflower is considered a beginner-friendly strain with moderate difficulty. The flowering time is approximately 6-8 weeks from seed to harvest, with total growth cycle typically 8-10 weeks. Expected yields are moderate: indoor growers can expect 300-400 grams per square meter, while outdoor plants typically produce 30-60 grams per plant. The strain performs well both indoors and outdoors, preferring a Mediterranean-like climate with consistent temperatures between 68-80°F (20-27°C). Plant height is compact, usually reaching 60-100 cm (24-40 inches) indoors and slightly taller outdoors. Special considerations include: the autoflowering nature means plants cannot be cloned; training techniques should be gentle (LST recommended, topping not advised); plants benefit from consistent light schedules (18-20 hours of light during entire growth cycle); and the purple coloration is enhanced by cooler nighttime temperatures during flowering. The strain is relatively resistant to common molds and pests but requires good air circulation.
