The element puts out UV but most all of it is stopped by the outer class coating. Anything that escapes likely won't get past the glass of my hood but who know - might be slightly more - can't be any less
I'm kind of hoping the decrease in light intensity will send the plants the message to finish the fuck up.
With the purpling I guess it could be genetics - the mother had pink pistils and slightly purple flowers but I haven't seen any of the pink pistils in any of the plants. Should I wait for them to get colorful? hehe, personally I think purple plants are pretty but could really care less when it comes right down to it.
