with cfls you can put the light as close as you want and in some cases even inside the plant as it gets larger with multi. tops, your seedling looks great btw!CFL's produce very little heat, I doubt that would be a problem, would it?
very little heat compared to hid. some cfls put out quite a bit of heat, especially in small areas. that said in this case i think you'll be fine for now. also, "how far away are you keeping your light? what wattage and spectrum? do you have a fan blowing in the area?" was not answered yet.CFL's produce very little heat, I doubt that would be a problem, would it?
