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 70%Sativa 30%

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 Blue Runtz

Our staple strain Grape Runtz crossed to the blue z. Both parents wash so expect hash dumpers. Terpenes ranging from blue raspberry to grape creme to z candy. This will be a commercial workhorse with a fast veg and massive colas if pushed. Best smoke will be at about 65 grams per sq ft. They can pack on a lot more weight but it diminishes the flavor.
