Summary

There are two main types of cannabis strains: indica and sativa. Growers have also created hybrids, which are a mixture of the two.
Indica strains tend to be used at night, while sativas are better during the day. Different strains can also be beneficial for different conditions. Indicas are often used for painful conditions, while sativas are often used for mental disorders.
Each strain has unique genetics, resulting in different levels of THC and CBD. Indicas tend to have more THC, while sativas tend to have more CBD.
