I ran mine @ 800 ppfd in the center and the ends settled @ 500 ppfd...And the only way you can have a even canopy is by training of your choice in the fight places. Sounds kinda a pain to me. Strains can help. Stretchy strains on the outside and the shorter bushier ones in the center. See wtf you have done. I been sitting here contemplating all this shit to for over an hour now. So I'm gonna try and stfu now.
