With this hydrologic digital water timer, you can set up to 4 cycles for each zone per day, with independent start times. Want to water at 8am, 12pm, 4pm, and 7pm? No problem. Water exactly when you want without the hassle of restrictive intervals. And, because unpredictable weather makes setting the ideal watering schedule difficult, use a moisture sensor to take the guess work out of when your plants have had enough water. When water conservation is a must, the sensor can automatically pause your timer when it rains or senses enough moisture in the soil.
