Automatic osmosis rain systems for small cultivation cabinets?

[Xara]

Keeping air humidity up manually has already proved to be hard in my new orchidarium, especially considering,my very effective brand new fans! Others use rain systems, I understand, but I'm new to this way of growing plants. What should I be taking into consideration? I've search this part of the forum, but if anyone has a checklist, it would be appreciated!

Is your orchidarium completely enclosed?

No, it's not. Haven't considered that.
