All of the orchids I have put in there were previously potted. The two big phaps orchids are a Sogo and Fuller's Gold and I've had them about 4 years. The catt has been around for 3 years, and the two small phaps are under 1 year in my care. I did this to keep the humidity and heat up. Plus my cats seem to think the heat mat that I was using under the orchids was a good place to sleep and ended up knocking my orchids off of the shelf. Multiple times I don't know how they will do but I hope makes them happier. I haven't had much luck with gettting any of them to bloom.
The aquarium tubing is to drain off the water because I didn't want to put a hole in the tank. It works like a siphon that they use to pull water out of aquariums. Since the terrarium sits on a shelf it will be higher. Suck on the tube end you have to create a vacuum. Once the water level in the tubing is below the bottom of the terrarium the water will continue flowing until the tank is empty. This method is what my family use to do to empty the small koi pond we had. The misting system is an exo terra monsoon rs400 found here Exo Terra : Monsoon RS400 / High-pressure Misting System
Also note that I saw that you can use Kylon Fusion spray-paint or Drylock latex paint mixed with concrete dye or acrylic paint can be used to paint the background. I saw it in the Dendroboards that some of the people used for their frogs so it should be safe for plants as well.
I also want to add other plants as well. I bought a small fern today from a reptile store in Las Vegas today. I'm also looking at some air plants, moss, bromeliads, and more ferns. I like the orchids but I want to have a verity of plants to keep it interesting. My next project will be a terrarium for neofinetia
