There are three different varieties of cannabis that are grown for their Tetrahydrocannabinol (THC) content: cannabis sativa, cannabis indica and cannabis ruderalis.
Sativa strains are characterised by long thin flowers and spiky leaves. They originate from equatorial regions where the growing season is hotter. They are not generally used for outdoor cultivation in colder, damper climates, although some hybrids can produce reasonable yields in these conditions.
