keep in mind there must be the underlying genetics to allow for a plant to turn purple, no matter what the environment.

headshake Reviewed by headshake on . What temp turns a plant purple? I've been reading around the forums and I noticed something about when a plant gets too cold it goes into shock and starts to turn purple. And I was wondering at what low temperatures do plants start to do that? I really don't care about what color my weed is, as long as it gets me stoned I'm happy. But when people see purple weed they instantly think that its some super dank shiet, hopefully my weed will be dank regardless but it would also be cool to have a few purple plants :smokin: Rating: 5
