I constructed mine as a fish tank(bottom broken out) attached on top of a large thermoelectric cooler. This provides for light, air movement, and temperature change b/c the cooler and light is hooked up to a timer. The temperature ranges from 58-72F. Then a tube brings in fog from an ultrasonic humidifier, which is also on a timer. I grow lepanthes and this setup works very well for them.
