These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →

About Granddaddy Purple
Genetics & strain profile
Granddaddy Purple Autoflower is bred by Quebec Cannabis Seeds from Purple Urkle and Big Bud, the same recipe as the famous California indica, with Ruderalis added so it flowers without a change in light hours. It is a 100% indica autoflower with up to 23% THC, it is easy to grow, and it sits in our beginner-friendly selection with our compact, balcony-friendly badge. It is a newer listing with no customer reviews yet, so the figures below come from our own grows; we will add grower reports as they come in. Purple Urkle brings the grape and the colour; Big Bud brings the size of the flowers and the yield.
How Granddaddy Purple Autoflower grows
Because it is an autoflower, it flowers on its own schedule and finishes in 7 to 10 weeks from sprout, depending on the phenotype and the light it gets. The plant stays compact in the indica mould — short, wide and thick-stemmed — which suits a small tent, a closet or a balcony, and the Big Bud side packs the colas tight, so keep humidity steady and the air moving in the last three weeks to prevent mould and mildew. Expect 5 to 15 oz per plant (about 140 to 425 g), indoors or outdoors, with the top of that range coming from a 5-gallon pot, 18 to 20 hours of light indoors or a full-sun spot outdoors, and light feeding; autoflowers burn on heavy nutrients. Outdoors you can start it any time from May to July and harvest before the frost. For the purple to show, let night temperatures drop in the final two weeks; a green phenotype is just as strong.
Taste, aroma and effect
Sweet and fruity, with strong berry and grape notes and an earthy, hashy finish — the classic Granddaddy Purple profile. The effect starts with a wave of euphoria, then a deep relaxation settles into the body: a night-time strain for sleep, sore muscles and switching off. At up to 23% THC it is strong. For the photoperiod version, see Granddaddy Purple; for other purple autoflowers, Auto Purple Kush; for the Big Bud side, Big Bud.
