Keep your lawn healthy and the garden green with the HydroLogic 2 Zone Digital Water Timer. Water when you want by selecting up to four independent start times on each valve. Choose to water on specific days of the week, or every few days, depending on your plant's needs. If rain is in the forecast, easily suspend watering for a day or two with the rain delay feature. Save water and reduce runoff with ECO mode. Need to do other lawn and garden tasks? Manual mode allows you to turn on the water whenever you need it. Each zone works like a separate timer, so the garden can be watered every morning while the lawn sprinkler comes on every few days. The dirt resistant valve ensures a smooth flow, even with sand and particles commonly found in well water.
