Right, yes you can get many strains of weed that are geneticly purple. BUT, if the temps are very cold during flowering it'll turn the buds purple.

Idiot dealers do this so they can jack up the price, so if your buying its hard to tell weather your actually smoking purple.

The only way to really tell if grow it yourself or by from a club.
LIP Reviewed by LIP on . purple weed? i just got a bunch of purple weed, and my friend that i got it from says its from genetics, but i smoked some with one of my friends and he says that purple weed only means it was cold towards the end of the grow and that there is no genetics involved with purple weed. i always thought purple was a phenotype for the cannabis plant. i need some truth!
