LST will be fine, I'm not sure that the plants discern the seperate light sources, so all around and above is fine. IMO, 6 inches is too far. I have a single 250w envirolite CFL that my plants are happy to have just an inch or so away with no heat damage. Lumens drop away quickly with distance, and more so with CFls than HPS, but as but as you can have them closer, this isn't really a problem.alright cool cool. If i were to lst with cfls should the lights be hanging above them if so should i still put it 1-6 inches away from plant// if not can i lst with the cfls around the plant but wouldnt it be crazy direction since theres light around the whole thing
