In 1785, biologist Jean-Baptiste Lamarck discovered that indica and sativa have different genetics because they grow in different environments. Indica originates from the regions of India and Central Asia, whereas sativa originates from East Asia.
Indica strains are known for inducing tranquil states that relax the body and mind by reducing stress. They also can produce euphoric highs. Indica’s trichomes naturally produce a lot of resin, causing these genotypical varietals (strains) to have plenty of crystal-coated buds.
This list is valuable for those looking for the strongest indica strains, whether mostly or pure indica. It identifies potent indica strains, their effects, and tips on how to grow some of the best indica strains yourself.
