Man, kush, kush, kush. Kush was a old indica strain that goes back years ago. Kush meaning stout, short. Why take a indica and try to cross the indica out of it with sativas. If you want a high get a land race haze. Now that's a high.
Skywalker OG is a pheno of OG Kush. Neither are related to the traditional Hindu Kush. OG Kush is almost a pure sativa strain. O.G. means ocean grown, no real good explanations as to why Kush was put into the name.
