I done an experiment in my last grow with deflating during flower and the side I deflated grew far less that the side I just left alone. I know its each to their own but personally I'll never deflate after week one of flower. In my opinion it shocks the plant a slows growth. I know I'm sacrificing the under canopy by not getting any light to it but I have between 4 and 6 major heads on every plant. Only reason I've kept a lot of the bottom stuff is for re-vegging. Otherwise I would have lollipopped it hard.If I was to do anything in their I would defoliate a lot of the leaves. As many as I could. And tie a twine around the perimeter to keep the buds off the walls. To reduce transpiration as much as possible. Just to make sure it's not staying wet and soggy.
