I got into the purple hype for awhile... But it gets old. The thing is, half of the "purple strains" that come around aren't actually purple strains, but in fact normal strains that turned purple due to a number of reasons: nitrogen deficiency, cold temp, fluctuating temp, etc, etc etc... Hell, if you wanted, you could go out and buy a product called ClearX that will flush your plant so hard it will turn purple as balls...
Nonetheless, I'm actually growing grape ape at the moment. I will say that up to this point, the plant has not ceased to amaze me. In fact, the buds are getting soo big, I have to tie them up. If you want to see more pics of my grow, I just started a thread
here.
