Hey all. I am currently working on a good sized enclosure for highland neps, tropical drosera, etc. I plan on using an ultrasonic humidfier but need a way to control it. I have heard of humidistats that can be used to conrol the humidifier. That is, the humidistat turns the humidifier on when the humidity gets too low. Does anyone know where I can get the necessary devices for this? Thanks.
