HI Myrrh,
Your orchids and environment look fantastic. Is the Hammerhead figure helping out? i know you are trying to grow moss on that platform with the E. nakaharai. i think that the sphag and moss transplants you have there should do it as long as you keep it moist.
nice job
now if i can find a way to up the humidity in my case maybe i will have something...

I have some ideas. i know you have the clay pebbles in the bottom of your case - they probably work better than river rocks since they leach the water upward and create more evaporative surface area.
I am working on getting my misting system going again. ...
