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 Old Red Sour
Old Red Sour by Old School Genetics seed bank is a variety from the Old School Never Dies series. The breeder Oldman Green has developed here a very particular breeding work. Oldman Green has successfully combined very distant aromatic nuances, such as an intense fuel flavour with an earthy Sour Diesel IBL aftertaste and a particular forest fruit and citric hints of two distinguished landraces. These landrace varieties, very much loved in Spain, are Jamaican Blueberry by Cannabiogen and Red Khyber by Alex La Mano Negra (R.I.P), a legendary cannabis breeder in Spain. Old Red Sour, a strain with old school genes
Old Red Sour is a super hybrid between Sour Diesel IBL x Jamaican Blueberry x Afghan Red Khyber. Oldman Green has used Sour Diesel IBL's famous clone "Riri cut" and a Jamaican Blueberry x Red Khyber male, a very special hybrid of his own creation. This male contributes with a better ramification and a more moderate stretching than the female Sour Diesel IBL. It is a plant with a fast development that maintains the rigidity throughout its entire life cycle. This strain inherits a ramified structure from the Jamaican Blueberry x Red Khybe male, which acts as a fairly Indica pla
