Programmable misting unit for terrariums and greenhouses 65.25 PSI water pressure pump Easy to connect and install Pressure resistant tubing & leak-proof connectors Flexible spray nozzles (up to 6!) can be pointed in any direction Large 8-litre (2-gallon) reservoir Easy to refill The Exo Terra Monsoon MULTI is a programmable misting system suitable for all types of terrariums and greenhouses. It helps maintain optimal humidity by generating a fine mist at programmed intervals, the duration and frequency of which can be easily adjusted depending on the type of animal or plant housed. Frequent misting helps stimulate breeding behaviour and is a necessity when housing live tropical plants such as Bromeliads, orchids, mosses, etc. The system can be programmed to mist multiple times per 24-hour cycle, with spray durations ranging from 2 seconds up to 2 minutes. The large 8-litre (2-gallon) reservoir ensures continuous operation for several days without the need for refilling (ideal for vacations!), and the reservoir can be easily replenished without needing to uninstall the entire system. The Exo Terra Monsoon MULTI comes with two easy-to-install nozzles, but the system can be extended to accommodate up to 6 nozzles, making it ideal for multiple terrariums. (Please note that every additional nozzle will result in less performance from each nozzle installed.) The mist produced by these specially designed nozzles is extremely fine, creating a fog-like effect in the terrarium or greenhouse, and the extra long tubing makes it possible to conceal the unit in a storage area or under the terrarium in a cabinet.
