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 30%Sativa 70%

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 C99

It was one of the first strains in female seeds that was launched at the birth of Female Seeds in 2003. But Ferry actually first started working on this strain back in 1999 and the first batch he produced of this amazing variety were regular seeds for a different seedbank. Years of experimenting with the original Brothers Grimm C99 led to the creation of our very own C99. The origins are difficult to establish, but it was a long flowering Sweet Tai landrace crossed with a short flowering Sativa. Most likely, the Durban Poison. The current batch we are selling was backcrossed to stabilize the genetics with two specially selected C99 phenotypes, a Grapefruit and the legendary Pineapple pheno. The result is the holy grail of cannabis strains, a fast flowering Sativa that has the taste and high of an exceptionally sweet landrace Sativa. A landrace that would normally take up to a half a year of flowering. Yet our C99 flowers in just 8 to 9 weeks. Our C99 has an unusually high CBD content for a Sativa strain. It actually resulted in a new chemotype, CBD-Sativa. The C99 does not stretch too much and grows like a dream, very vigorous. If you really want to maximize yield, we suggest you v
