Hey Sns crew,

db, when I first replaced the MH 400's I could tell light penertration would be an issue that's why I went to light mover and fan... and it made a big difference.

I try to keep my moms short and fat, about 3' max. Had to put a few 4'+ plants in there from my greenhouse and their lower growth suffered some. Taller plants might need some supplemental lower light.
IMO if you stay shorter and bushier there are no problems to the Procyon.

BTW I was glad Ryan took care of you (nice guy, I knew he would) now the question is how much better is the new light vs. original. Have you noticed a difference?
