The Exo Terra Mister helps maintain optimal humidity. Frequent rainfall helps stimulate breeding behavior and is a necessity when housing live tropical plants such as Bromeliads, orchids, mosses, etc. The Exo Terra Mister provides a source of hydration for chameleons and other reptiles that require drinking water in the form of rainfall. The Exo Terra Mister is an easy-to-use pressure mister that eliminates the chore of using trigger sprayers. The spray nozzle can be adjusted to allow either single stream or full mist spraying, and it has a locking mechanism that allows for continuous spraying. The large capacity reservoir holds 67.5 fluid ounces and is ideal for use with large or multiple terrariums, outdoor set-ups, and in greenhouses.
