A strain of Cannabis, almost solely of the Indica variety. The name "Kush" originates from the Hindu-Kush mountains where it was cultivated for thousands of years. This sweet smelling plant is part of the Cannabis Indica family, which leads the plant to be short and squat in appearance. Some forms of Kush, however, are in fact a hybrid between Cannabis Indica and Cannabis Sativa...which leads to greater harvests. Varieties of the Kush plant include,(But are not limited to), Hindu Kush, OG Kush, Purple Kush, Master Kush. Many crossbreeds exist as well.
