ouch man! yea you really need to lower that light!!! i keep my 400's about 12 inches away, and they arent even air cooled! 26 inches from a 400 watt is a HUGE waste of energy. trust me, lower the light to 12 inches and your yield will do 10x better. if it burns the plant, ill pm you my address and you can come throw bricks through my window.
