I'm setting up a terrarium for mounted orchids. The tank measures 24x12x18 with a glass canopy covering about 75%. I'm going to start out with a singleT8 florescent tube
knowing that I may need to increase the light level, but I want to cover the substrate with Bryophytes, so this will be a low light high huimidity environment. I'd really appreciate some advice on orchids that would be happy in this set up.
