Get a chiloshista.
I have a small terrarium placed next to a white wall, next to a radiator, next to the window. I have potted phalaenoppsis' placed on top and hung above them i have various cool orchids mounted on bark... when i mist the mounted orchids/water the phal's. excess water drips through the ventilation gaps in the terrarium lid, down onto the bark in the bottom of the terrarium. Plus i spray my chiloshista & ghost's. in the mornings.
Fun!
I am going to get a small (vivarium) heat mat for in winter. I don't want heat to go down, so i will place under the terrarium so the heat will raise the humidity
