So im thinking about putting in either a 600 watt hps in the middle of it, or 2 250 watt hps lights hung up about a foot away from each other. My question is would the 2 250 watt lights be more efficiant if im using as much floor area as possible for growing? i know the total lumen output is less, but think about it. light dissipates exponentially fast, so once the light gets about 2 or three feet away it loses about half its output strength. as apposed to one light in the center hich is far from the walls cause plants on the edge to suffer, im thinking to put the 2 250 watters in side by side to get rid of some of that space between the lights and the edge of the room. Am i right on this or just wayy to overthinking it lol
