Indica / Sativa — retail shopping guide

Indica 70%Sativa 30%

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 Purple Tuna

This is another KropDuster Original. I took a B.C. favorite and local strain BLACK TUNA F4 and crossed it with my PURPLE MEXICAN HEIRLOOM IBL. The results are epic. A tall plant with dense purple buds and covered in trichomes. The aroma is heavy musky earth with a hint of sour. The layout of the plant is more sativa like. More space between the nodes. She will finish in 9-10 weeks and put out some killer buds.
