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 50%Sativa 50%

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 School Skunk

This pack includes two different phenotypes selected by Oldman Green himself (13 seeds of each phenotype). The first phenotype differs greatly from today's typical selections by its strong skunky stench, as the descendants of Skunk #1 usually stand out for having a sweet and fruity aroma. The second phenotype is similar to the first but not as original or interesting, although it maintains the Skunk essence. Old School Skunk, history in the cannabis scene A bit of history can help us understand the significance of this strain. It was originally developed in the US and introduced to Europe in the early 80's by Sam the Skunkman, a Cultivators Choice member. Skunk is also the base strain that founded most of the early seedbanks in Holland. It is a plant with a very narrow structure that can deceive the grower, yet they are great producers. It develops typically Sativa leaves, long and narrow, acquiring purple colours once it enters the flowering stage. It offers a high production indoors, with a yield of more than 500g per m2 in about 65-75 days from the change to flowering. Outdoors, it offers a yield of over 600g per plant. It produces rotund, curly flowers that are ready to harvest
