Tired of coming home to dead, dry plants every time you leave your home for a few days?These auto-drip plant watering devices give you peace of mind by automatically watering your plants at a steady rate.Reuse old plastic bottles (not included) to reduce waste and help protect the environment.No tools are required for installation -- simply fill a 1-inch plastic bottle with water, attach it to one of these devices, and insert it in the dirt near your favorite plants.Tip: Always make a small hole in the bottom of the bottle to make the air pressure inside the bottle consistent with the outside so that water can drip properly.
