Managing the water needs of lawns and gardens doesn't have to be a hassle. The Rain Bird ESP 12-LX Plus is a modular programmable irrigation controller capable of controlling up to 12 sprinkler valves at a time. When properly configured, ESP-LX series controllers can run up to four custom watering schedules to give you high-precision control over even large and complex irrigated areas. With just a little effort you can create a basic program that will keep plants green and prevent excess water use from running up your utility bills.
