Looking for "micro" orchid suggestions
Looking for suggestions on "micro" orchids for a small, enclosed terrarium. I was inspired by a YouTube video, and while I have moss, I thought it would look neat with a micro orchid. The container is round, about 8in/20cm high, and 4in/10cm wide and they would be mounted on wood of some sort. I know a lot of the tiny orchids have an air flow recommendation. I would set it up with air space around it and ths terrarium won't be cluttered. See picture for my inspiration. (Created by u/6spadestheman a few years ago.)
I have on hand a small dendrobium ecuagenera rainbow, bulbophyllum (can't recall the type, super small), and a tolunmia sylvestris that could all be divided. Are there other species you think would do alright in that kind of set up?
ETA temps: My temps range from cool to intermediate. About 72⁰F/22⁰C high in the summer (68⁰F/20⁰C in the winter). Down to 62⁰F/17⁰C summer (54⁰F/12⁰C winter).
