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 Romulan Haze

An amazing sativa hybrid, our Super Silver Haze female that was selected was shorter and stronger than the other females and then we introduced her to our Romulan stud. Unsurpassed quality, featuring the best of Holland combined with North America’s top cerebral knockout. Recommended medical strain, a one hit wonder. Spicy taste and smell we know you will enjoy. Indoors: flowers 60-65 days
