Hey sorry to stir things up a bit, but what are you looking to accomplish with the MH after the stretching stops....I understand that some use that "blue" spectrum to keep the plants from stretching so much, but from what I heard (correct me if i'm wrong) the blue during flowering tends to give you more of the "fluffy" type buds rather than tight dense buds. I myself don't see any benefit from putting the MH back in after mid flowering with the HPS.

Sorry to be such a pain in the @$$ but I'm curious sometimes! :jointsmile:
