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.
Flowering type
Autoflowering This is an autoflowering cultivar — a genuine ruderalis-derived genetic trait (it flowers by age, not light cycle). That’s a real, heritable distinction, unlike the indica/sativa label above.
