Bred by growers in the Oakland, Purple Kush has become a stable strain when it comes to pure indica weed in the West Coast. If you started smoking weed in the early 2000s, there is a good chance that you’ve toked on the original PK a handful of times. As a cross between Hindu Kush X Purple Afghani, PK comes from a potent indica lineage. The high starts with a warming body sensation, which quickly spreads to the head. Purple Kush’s couch lock effects make this strain an ideal choice if you have trouble falling asleep.
