Automatic Plant Drip Watering System with Coil Spill Free Bucket 10 Plants Automatic Plant Watering System waters up to 10 potted plants while you're away. Just attach the battery-operated pump to the included coil spring bucket, fill with water, and run tubing (32-1/2 feet included) from the plant watering system to each plant, cutting enough tube to comfortably reach the soil and securing in place with a clip. (10 clips included.) The 4-gallon bucket has a coil inner frame to keep it from collapsing as the water level goes down. A timer on the Automatic Plant Watering System can be programmed to adjust the amount of water and frequency of watering, anywhere from 5 times a day to once a week. This automatic container watering system also has an LCD display that shows your settings, with visual and audible alerts when battery or water is low.
