It's 2 600's back to back in cooltubes, exhausted out of the room. I'm thinking 4 large plants arranged like a square? What do you guys think? What would the optimum canopy distance from the light? I want them far enough away to give me plenty of surface area, but not far enough to hurt density and quality. I'm going to set up a screen. Either in a cylinder on the inside of the donut, or around the outside of the donut. I've seen it both ways, but I'm not sure which will work out better.
Any advice or tips would be greatly appreciated! I'll put up some pics when I get my clones in the buckets.
