Jewel Orchids in high humidity and wet environment

[Longroots]

I want a few Jewel orchids in the bottom of this cool growers cabinet. They'll be in a fairly consistent 19-23c environment with 70-95% humidity. This Ludisia Discolour is doing things, and all 3 cuttings were a bit 'eh' before moving them in here, but the leaves they did have have dropped. However, they didn't have any new growth.

Before I put any jewels in there, I want to be sure they don't rot due to the regular spraying. There's a thin layer of moss on top, with a good layer of leca below. The moss never even gets close to drying.

Any thoughts if I should put Masdevallia in the bottom instead, as I wonder if they would do better? Or any other creeping habit orchid?
