Hi everyone
I got this orchid back in June this year. It was (still is) very tiny and had barely any roots so I wasn't sure how it would do in my terrarium.
The sphagnum it's mounted to is usually quite dry, almost crispy. Not by choice, but it doesn't seem to absorb much water when i water it! I might remount it at some point in the future, but I didn't want to touch it yet as it arrived mounted.
Looks like it doesn't mind it at all.. from memory I think this is an agraecoid, so I haven't been too worried about the dryness.
Here's a couple of photos in it's "habitat", and a photo just to show how small it really is in comparison to the rest of the terrarium!
