I have a warm humidifier with PVC piped into my water dragon enclosure. I have a dial on the front which adjusts the amount of humidity and a timer for turning it off intermittently throughout the night. What I really want is a humidistat to keep the humidity between 60-80%. I have seen this combo set on Amazon and in a pet store, but wanted to know if anyone else has used something (hopefully a little cheaper) to control humidity.
