Indica / Sativa — retail shopping guide

Sativa 100%

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 Mekhong Classic

Mekhong is a rare and authentic Southeast Asian landrace sativa selected from over 1,000 seeds preserved and cultivated for countless generations by a local grower. The seeds were gifted in 2022 by a 91-year-old woman who had maintained this genetic line continuously for most of her life. Named after the Mekhong River—marking the natural border between Laos and Thailand—this variety represents one of the oldest cannabis lineages documented in the region. This pure sativa landrace stands out for its exceptional resin production, rich cannabinoid diversity, and outstanding resistance to pests and fungal diseases. It is remarkably resilient and capable of thriving in harsh, tropical, and subtropical outdoor environments where many modern hybrids struggle. Mekhong is best suited for outdoor cultivation in warm climates. While it can be grown indoors or in temperate regions, it presents challenges due to its long flowering cycle and sensitivity to stress. The plant does not tolerate topping, heavy pruning, defoliation, or rough handling and may express hermaphroditic traits if stressed. The terpene profile is fresh and distinctive, dominated by crisp green apple aromas. With extended cu
