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 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 Grapefruit

The initial Grapefruit was created in 1998 as a regular strain from a special C99 clone crossed with a Thai Sativa and an automatic strain to improve flowering time. So, this strain has been around for nearly 20 years! Grapefruit was improved over the years and the female version was launched in 2003 at the start of the company Female Seeds. The Grapefruit currently being sold stems from an amazing line Ferry created in 2007. The parents of that line were selected on two criteria: the amazingly strong Grapefruit/Pineapple smell and the moderate height of the phenotypes. It is an extremely fast flowering cannabis strain. Grapefruit, from the start, has always been an amazing yielder of lusciously smelling bud. The current Grapefruit has been stabilized over several generations resulting in an early maturing and massive yielding beast. Make sure you have the humidity under control in the latter stages of flowering and that your ventilation works. As once these babies fill up the buds can be susceptible to mold. The Grapefruit is a highly praised and highly sought-after strain due to the amazing smell and taste. The outstanding sweet and sour taste of pineapple and grapefruit is truly
