Purple weed comes from a cold climate that the weed was grown under and purple haze is suspected to be the strain also known as purple punch or purple power. KB is kind bud which is pretty good if its the real strain and not somethen someone said just to get there product moving. White widow is a strain has a really high potency its very uncommon just to stumble on some white widow unless u personally know the grower.O ya and 20 bux a gram for real purp isnt bad but it probably isnt the real strain cause its pretty hard to find.
