alocer, i'm sure that would work for smaller indoor grows, like mine, but (i think) what they're doing is trying to duplicate the old "arc of light" that we were doing back in the early 80's, in that we were trying to eliminate all the shadows & developing all the flowers we could off the plants. u have to understand that back then i didn't even know what scrog or sog was. lol! lighting engineers will tell u that a moving light source (ie. the sun) will diminish the likelyhood of shadows. of course i could be all wrong!
