Tillandsia air stump, ideas?
 

I scored this drift wood stump stuck on an old hospital IV stand a couple months ago at a nursery that was closing.
I stuck a T. Stricta and a T. Victoriana on there and they seem to be doing well. I was wondering what might be some good orchids to try on there? It's in a west facing window that gets pretty bright indirect light all day except for like an hour of full sun around sun down, RH is usually about 45-60%. Thinking about moving it to the porch when it gets warm.

I've found that Tolumnia orchids grow well when mounted near Tillandsia plants like that. More experienced growers will have to chime in if they can handle humidity at that level. You would definitely have to mist/water every day.

I think a pendant type Dendrobium such as loddigesi or parishii would do well and look amazing cascading down from the mount.
