Thanks bachelor. Yea, I don't really feel like messing with screens and all that for my first indoor. Which do you think would be better, one 1000 or the 600 up top and the 400 below it? Also, what if I shaped the room like an octagon with 5 equal sides, or maybe with 6 equal sides? I could then put either 5 or 6 plants around the light/lights, one in each corner, right? That might help guarantee a good yield for me I'm thinking...
