Seeking terrarium recs

[nzadro]

Hello,
I am seeking recommendations for true miniature orchids for my terrarium. This enclosure also houses high humidity begonias. It is 12x12x18, and has a single led grow light strip along the top.

The terrarium runs 70-85% humidity in the daytime, can run upto 90%+ in night. Temperature is between 70 and 80 degrees F. There is not much fluctuation between daytime and night time temps, since this could shock the begonias. Future plan is to have a separate enclosure for the two so I can make everybody happy in there.

Can anyone recommend any mounted orchids, for the current conditions?
I currently have haraella retrocalla, dendrobium unicum and trichocentrum tigrinum.

Thanks
Natalie
