That one seems half decent. The humidifier I have looks like its from the 1950's, but I may just set it up on a timer and duct it into the enclosure.
My humidity now stays around 52% which is a little low for my liking. It seems like it will be quite difficult to maintain 70% during shed in a glass tank.
kitedemon - Does that model have a probe, or does it measure right of a sensor on the machine?
