Purple Hindu Kush is a rare and almost pure indica with dense purple flowers littered with orange pistils and a thick layer of trichomes. The bud is exactly what you would expect from a pure indica. The high is sedative and eases in with full-body relaxation and is a favorite among chronic pain sufferers. PHK is a cross between Hindu Kush and Purple Afghani that has a sour grape and citrusy flavour that is pronounced on the inhale.
