The Hydrofarm Electronic Water Timer makes watering your plants a breeze. This single-station analog timer attaches directly to your garden hose and automatically controls sprinklers, drip systems or soaker systems. It features two simple dials that allow gardeners to set the frequency of watering from 1 hour to 1 week, and the run time from 1 minute to 2 hours. This timer is easy to use and requires no wiring. Just attach it to your hose, set it, and forget it.
