So, I love Indicas and I loooooove it when they have purple on them. I don't know why, but whenever I find a strain with that purple hue on the bud it interacts totally differently than other strains with my body and I always feel ultimate relaxation and pain relief. Thus, why I love purps (especially Wheelchair! If I ever can find that strain to grow, I will be in heaven). The other day, I was talking to a dispensary guy and I asked why the purple kush they had... had no purple whatsoever on it. He mentioned something about temperature and cooling and that it doesn't mean anything if purple kush doesn't have purple on it and so on. It all made sense, but I have very beginner knowledge of growing so I thought I'd check up on it. I know that cooler temps can cause purplization on the strain, but why is this? Is it true that strains that are known for "purple" often have no purple in them? If I start growing, how can I be sure I get that purple on my buds?
