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 South Indian Heirloom

Genetics: Idukki District, Kerala (South India) Sex: Regular Type: Sativa Flowering Time: 16–20 weeks Yield: Medium–High Suitable For: Indoor, Outdoor, Greenhouse Notes: A treasured long-flowering sativa landrace from the Idukki region of Kerala in southern India. This line was originally gifted years ago through a trusted connection with links to India, and it represents a classic tropical expression that helped shape early exploration of heirloom genetics. This cultivar shows exceptional vigor from the start, driving strong vegetative growth before developing into a wide, open, bush-structured plant capable of substantial size outdoors. It is highly adapted to heat and intense sun exposure, maintaining momentum through demanding conditions where many other varieties begin to decline. Its long, flexible, vine-like branching makes it especially receptive to training. The structure opens easily, allowing for effective canopy management, improved light penetration, and low-stress shaping throughout growth. The flowers remain true to its origin—resinous sativa formations with medium to heavy production. Aromatically, it presents a deep earthy-fruit profile, combining rich soil tones a
