Maybe the bathroom? It gets warm and steamy. If there's a happy window to place or hang them near. Maybe. I can't remember if orchids do well that way. I know bromelieds do.Sadly they didn't handle the stress of moving back to Texas. So I've started anew.
I came across some "seedling" (to young to bloom) orchids that were on sale because they weren't doing well. So I did a plant rescue attempt, still waiting to see if they pull through.
I had them many of them outside because they were more heat loving types, but then we had some cold so I brought them in.. they don't like being inside.
