Indica is one of three species of the genus cannabis. This family includes: cannabis(sativa) cannabis(indica) and rudaralis. Cannabis sativa plants tend to be tall,skinny with long leaves. Cannibis indica plants are shorter,fatter and tend to be denser. Rudaralis is not very common for production due to the fact the plant does not flower based on season, but rather on plant maturity, and contains small amounts of THC (tetrahydrocannabinol).
