Make sure the timer you get is rated for more than 20 amps. Keeps the fire dept away.just ordered 1000 watt lights has mh and hps bulbs included and dig ballast and timer should be here within a week or so . cant wait to get it . i already a single wire ran back there with its own 20 amp breaker sure dont want to cause a fire with ext cords and have fire department and police here that would suck worste than having tiny harvest
