Chemotype
Type I
THC-dominant
Terpene profile most dominant first
Chemotype — the cannabinoid and terpene profile — is the 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). The dominant terpenes below are aggregated from community and lab reporting; aroma and effect associations are preliminary and not medical claims. Lab-verified COA profiles roll out as Areto’s 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 Viper
As a medical cannabis patient John Sinclair has always appreciated potent marijuana. The powerful Viper has an intense physical effect that relaxes you without the ‘knock-out effect’ that for instance a Skunk provides. It gives the sensation of walking through the surf or on the moon while still allowing you to get on with your day in a normal fashion. Indica strains are the crop of choice in most areas around the world where hashish is produced. It is therefore no coincidence when the taste of John Sinclair Indica takes you back, in spirit, to the mountains where this variety originated. John Sinclair Indica is a short, compact and fast flowering plant that abundantly produces tightly clustered, resin-covered buds that have a light but distinct herbal, almost musky scent. John Sinclair Indica has few leaves and those leaves are relatively big which makes for quick and easy cutting & curing. Breed: (Indica x Skunk) x Indica
Flowering: 55-60 days
Yield: 0.9-1.1 per Watt of light
