Sorry for digging up an old post, but I have a couple questions about your orchidarium build. Did you build the frame yourself? If so where did you find the aluminum extrusions? Also did you use glass or acrylic?
No problem! Every post is there to be read and to be explored again and again!
Yes, I built the frame by myself because I wasn't able to find what I wanted in the needed dimensions. I bought this type of extrusions, here: http://www.8020.net/Quick-Frame-1.asp I found the prices and service to be really good.
I did use glass for the all the orchidarium and bought the rest of the accessories at my local hardware store. Aquarium silicone has been used to seal the glasses on the alu.
Not really... Maybe only the set up for cooling the temperature at night. I actually use an air conditioning unit that exhaust in another room... It's noisy and not really nice to have a dryer hose on the floor I thought at first that not heating the room would do the job but finally, it doesn't. I tried to find another way to cool it but I didn't find something better and smaller. So, I stick to this solution since it's working. Maybe someday...
