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 Callahan

Columbian Gold will add some dimension to the Herijuanna, both structurally as well as effectiveness. Both strains are heavy resin producers, trimming will be a gooey nightmare. The pure Columbian Gold is not for the novice grower and in the past has shown that some experience with Sativa’s is required to grow them properly. The Callahan is just the first step towards a poly hybrid IBL. It will be in limited supply and it is doubtful that it will ever be reproduced again. This cross is not for novice growers or smokers. Top heat can aid with the very slow germination. At 80°F, may take 3-4 days. Germ tested. Experimental. Flowering Time is Less Than 70 Days
