The Exo Terra Monsoon Nozzle Extension Kit allows you to expand your Monsoon misting system by adding an extra spray nozzle. The kit contains one easy-to-install nozzle plus tubing, enabling you to mist additional terrariums or extend mist coverage within a large enclosure. You can add up to 4 extra nozzles to a Monsoon Multi system (for a total of 6) to accommodate multiple tanks. This extension kit installs in minutes and lets you grow your automated misting setup along with your collection.
