I just built a large orchidarium myself and read somewhere about putting plastic sheets on top between the case and lights. This cuts down on the heat emitted by the lights Mine seems to be working OK so far.

Bert, acrylic is a bad idea. With the high humidity and heat, a sheet that large will warp and bow. I use window glass in my temporary setup and it works well. The heat from a bank of lights like this will increase temps about 18 degrees F without a fan. With a fan blowing through the lights it's a modest 8-10 degrees F.

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
