As you see, I've opted to mount the plant. It was originally in a tree fern pot with moss. I looked underneath the moss for the roots and saw how stunted and ugly the roots looked. Hence my decision to mount.
But there's also a reason why the plant was originally grown in a tree fern pot with moss...
It loves water.
It's like growing a Vanda alliance version of a Pleurothallis or Lepanthes.
You can't skip a beat or the roots start shriveling. I try to not allow them to dry out at all.
They like moderate to high humidity. I think the flowers on mine had some trouble with the petals getting stuck on the sepals quite possibly because the humidity may be short a hair. I'd shoot for a humidity of about 70% - 80%.
It's mounted over a thin layer of moss, but the moss is covering the entire mount to keep from drying out too fast.
Lighting is preferably bright shade. It can take it a little brighter or a little shadier.
I have to grow it intermediate because of the humidity and water regimen. But it can take it colder.
Moderate to good air circulation is good.
I have one basal growth on mine too! What do you know!
