Master Control Hydroponic Timer. http://www.hydroponicsgroup.com Our Master Control digital timing system houses up to two 400 Watt ballasts in a fan cooled environment. It will automatically run two grow boxes or two grow tents independently of each other in either 18/6 or 12/12 cycles. Timed CO2 emissions plus on/off plugs allow you to run everything out of this one unit. Easy to program, easy to run.
