Chemotype genetics-true
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 Congo x A5 Haze
Congolese x A5 Haze is a sativa-dominant polyhybrid created by crossing our strongest pure Congolese sativa mother with Neville’s A5 Haze from the late 1980s. This new A5 hybrid produces highly branched, vigorous plants with bulky flowers and an excellent flower-to-leaf ratio, making it ideal for growers seeking large, quality yields.
Compared to the Bangi Haze × A5 Haze cross, the effects are cleaner, more energetic, and less intense, offering a highly enjoyable, uplifting sativa experience. The aroma is complex, dominated by woody, floral, and incense terpenes, perfect for connoisseurs of classic Haze profiles.
