Hey, i upgraded my setup a little. I have 3 40 watt fluorescent tubes lined on the wall and one 40 watt tube that is for plants with 1900 lumens. I have 2 Cfls hanging, each is 2600 lumens soft white (how close should the cfls be?) i am still trying to find some mylar to line the walls. how am i looking? should i get more cfls
