Fill Froggy with water and he slowly releases water into the container soil through a special terra-cotta wicking system. Plants always get just the right amount of water. You’ll never have too-wet or too-dry pots again. Plus you won’t have to water every day – froggy dispenses water slowly and evenly lasting 4 days or more. Simply insert froggy into any houseplant container and fill his smiling mouth with water, that’s all there is to it. A quick glance at the transparent body and you see how much water has been used and whether it needs to be filled. Height: 6 ½ inches.
