Have you tried the Terracotta Mounting Jar?
 

Has anyone ever tried the terracotta mounting jars? They lack a drainage hole in the bottom, and you just fill the jar with water. Seems like an interesting way to display your orchids.

It's the first link in Google:Terracotta Mounting Jar

I don't know about those but I have my masdies mounted on Kool Logs. You mount them on the outside of the white terracotta 'log' and keep the inside of the log filled with water. Keeps them cool and moist.

No I haven't but I did see them somewhere, can't remember where. I would think they would work the same way.

It basically is a physical feature of some kinds of clay to sweat like this. Even old fashioned red clay pots do this. I have had plants in rocks in a smaller pot held inside a larger pot filled with sphagham moss (around the central smaller pot) and the pot remains slightly damp and cool. In areas with no electricity, they make (or used to make) water coolers in large clay pots that work this way as well. They have to be in the shade though.

i have a couple of orchids mounted on clay pots... i got cheap pots from the 99 cent store, plugged up the bottom hole with some polymer oven bake clay... then drilled two holes on them with a diamond hole bit...

here's a cattleya i just mounted the other day... shows the plug too...

you can get some at walmart in the art section that don't have the hole in the bottom... also, micheals i think... but if not, you can get some polimer clay for 3 bucks and plug up a bunch of pots in a toaster...
