I normaly run a couple 400hps this run is an experiment, it will be done with cfls.I am trying to lower electric bill, I believe there are a couple of males on board and my space will open up if not I have a identical set up on hand, I am using 8 26 watt on lid plus back and side lighting as well, so far I am impressed with how bushy plants are temps stay at 70deg constant, they will be tied and kept low. Thanks for replys.
