Purple Kush is a pure Indica strain created by crossing purple afghani and Hindu Kush. Hindu Kush is actually a very purple strain also so you can see why Purple Kush turns out the way it does. When grown from clone, purple kush grows dense and squat with moderate branching. The high is very sedative, exactly what you'd expect from a pure Indica. The aroma of Purple Kush is very distinct. It smells like purple cotton candy with a skunky undertone.
