This is my first orchidarium. I must admit my methods are crude at best. I have not been above using various random objects that I had laying around to lift the plants to the perfect light levels. It isn't exactly the most aesthetically pleasing way to grow, but my plants seem to be doing ok.
I use a 250 watt Metal halide as the light source with a large box fan to blow the hot air away from the glass top. I also use a crane cool mist humidifier controlled by a zoomed hygrotherm humidistat. I overkilled the air movement as I have 3 fans running in the tank at all times. Perhaps the equipment isn't ghetto it's the look of the display...lolz
