Cannabis Sativa L.
Sativas generally originate in the equatorial regions – Thailand, southern India, Jamaica, Mexico, and so forth.
Sativa buds tend to grow larger than Indica, as they run along the length of a branch instead of clustering around the nodes. However, they will usually weigh less than Indica when dry, due to their lower density.
Sativa buds also tend to have a less striking odor, both when growing and when dry.
