I consider there to be 4 types of marijuana that people smoke. Sativa, Indica, Ruderalis crosses and the forgotten or mistaken Afghanica. I have grown lot of Indicas and a few Afghanicas and there is a difference between them and I think a lot of people mix them up. I don't consider a true Kush a true indica I think of it as an Afghanica. Has fatter leafs and smells like hash when dried. The dominate smell is not a sweet smell like most indicas.
