I am just about ready to finish up my wife's aquaponic/hydroponic grow room, but I decided to wire her 1000 watt HID ballast at 240v. The multifunction, self contained, controller I bought, only has a 120v. receptacle. What is the best piece to use to relay the 120v to 240v. Without humming or chattering hopefully. I would greatly appreciate this help. Thank you for your consideration regarding this matter.
