Take a look at this link How to Build a Four Light Grow Light Controller for Less Than $80 It looks easy enough to build and I have a gas dryer with an unused 240v dryer outlet. My question is do my ballasts have to be 240 also? I'm planning on running 4/ 600 watt hps with this setup. Or should I just run 2 new 20 amp breakers in my box? I have room for 2 more breakers anyways?
