Fogger

This ultrasonic humidifier is ideal for the control of humid set ups and best used with a humidity controller. The pipe is easy to extend to the desired length into the enclosure. The fog output is adjustable and makes for a dramatic look. 

(Always pay attention to ventilation and humidity in your set ups) always best to use a controller with a unit like this or have a very large well ventilated enclosure. Stagnant air with poor flow is asking for respiratory illness.
