Hi guys! I'm have lots of experience with traditional HID systems, but none with ceramic metal halide. In my new cabinet I would normally use a 600w MH/HPS in a cool tube, but I want to try CMH to lower heat in the surrounding space. The grow space has floor dimensions of 56" x 30″ with an interior height of 68"+-. Should I use one 315w system, a 630w dual bulb system or use two separate 315w systems on either end of the cabinet? I am using a Hydroponics Group Grow Daddy cabinet. Thanks!
