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 Haarlem

Gage Green Group has combined two world-class parents to create a new hybrid variety that sets a new bar in connoisseur quality. East Coast classic meets a lucky male from Amsterdam’s Breeders Choice collection to create a super potent and medicinal strain that will relieve a variety of symptoms like insomnia, stress, anxiety, depression, and nausea. The East Coast Sour Diesel is a high-yielding Sour Diesel variety that has a slightly fruitier smell and taste. It is a nice hybrid with uplifting and euphoric qualities. The Anesthesia is more of a heavy-hitting indica-dominant variety that has a intense sedative effect for those needing maximum physical relief. This plant will finish in approximately 9-10 weeks depending on the specific phenotype. The buds pack lots of weight and density so keep an eye on the humidity levels to prevent mold. The hybrid produces a sweet diesel aroma with a "hint of citrusy grapefruit" and "tart fruitiness" according to Dr. GVZ. Haarlem will also produce a tremendous amount of resin for bag appeal. Genetic: East Coast Sour Diesel x Anesthesia Indica/Sativa: Sativa/Indica Hybrid Flowering time: 8 - 9 Weeks Medicinal qualities, High Yields
