Our Stormy Dripping Rain Cloud houseplant waterer by THE CLOUD MAKERS is a decorative item for watering your houseplants. These Rain Clouds turn watering your plants into art by dripping water like a gentle rain. The clouds rain for up to 10 minutes and are not meant for extended watering. They were simply invented to bring joy to your regular watering routine. I find it soothing and visually pleasing and the slow drip gives your plants more time to absorb the water. Makes a wonderful gift for the plant lover in your life. Each cloud holds 4oz of water which drips in a slow pleasing manner thanks to our patent pending design.
