Chemotype genetics-true
Chemotype
Type I
THC-dominant
Chemotype — the cannabinoid and terpene profile — is the lab-verifiable signal that stays true to a cultivar’s genetics, which is why scientists classify cannabis by chemical profile (a “chemovar”) rather than by name (Hazekamp & Fischedick 2012). Cannabinoid type is set largely by a single gene (the THC:CBD ratio); about 96% of commercial flower is Type I, THC-dominant. Terpene profiles are sourced from Certificates of Analysis (COA) and roll out as Areto’s lab-verified data comes online.
Indica / Sativa — retail shopping guide
Indica, sativa and hybrid are a retail shopping convention — not a reliable guide to genetics or effects. When researchers analysed 89,923 commercial samples across six states, these labels did not predict a plant’s terpene or cannabinoid profile, and a genome-wide study found sativa- and indica-labelled plants to be genetically indistinct (PLOS ONE 2022; Nature Plants 2021). The labels are so fluid that AK-47, a hybrid, won “Best Sativa” at the 1999 Cannabis Cup and “Best Indica” four years later. For an accurate, genetics-true picture, see the chemotype above.

About Granddaddy Purple Autoflower
Granddaddy Purple Autoflower is an autoflowering indica version of the iconic Granddaddy Purple (GDP), combining Purple Urkle and Big Bud genetics with ruderalis for automatic flowering. GDP is famous for its deep purple colouration, grape-berry aroma, and powerful indica effects. This autoflowering version makes those qualities accessible without a photoperiod schedule. Available through Seed Supreme. Genetics & Background
Granddaddy Purple was created by Ken Estes in California in 2003. The original Purple Urkle x Big Bud cross produced a strain with distinctive visual characteristics — deep purple buds, bright orange pistils — and a complex berry-grape terpene profile that became iconic in the US West Coast market. The autoflowering version preserves this heritage with added growing convenience. Effects
Granddaddy Purple Autoflower delivers a powerful, relaxing, full-body indica effect. Reported effects include:
Relaxed — deep physical relaxation throughout the body
Sleepy — strong sedation at moderate to high doses
Euphoric — initial cerebral uplift accompanying the physical effects
THC typically ranges from 17–23%. Best suited to evening use. Flavor & Aroma
