Add beautiful, oxygen-producing houseplants without taking up precious surface space. Ideal for ivies, kitchen herbs, strawberries, even orchids! The Sky Planter™ conserves water with a unique terra cotta Slo-Flo system that feeds water gradually to plant roots. Since you water from the top, the interior terra cotta disk not only holds and releases water but also prevents leaks. Create a lush hanging jungle or food garden near any window.
