Is it ok to only have air circulation from the top?

[ThePizzaMonster]

Hello. I've seen recommendations not to put orchids in a tight decorative pot not to restrict air circulation. However, I have this orchid (prosthechea cochleata) potted in a quite coarse and not very water retentive media (gravel, coarse bark and pieces of terracotta). Wouldn't it just keep a humid environment inside the pot and let some air come in from the top?

I'm just trying to use a very common (at least here) and cheap kind of media and not have to water every single day
