Plug & Grow Heavy Duty Timer
The only timer you can buy capable of switching upto 600w HPS or Metal Halide lamp without the need for a seperate contactor unit.
Simply plug your ballast straight into the timer and set your on/off times on the segments (each segment is 15 mins). Also the reliable safe way to switch your CFL lamps, up to 1500w!
King of the Castle Tip: These heavy duty timers are totally different from your standard household timer!
