D. Lai Klang needs a pot - maybe?

[Dewie7]

I have a small D. Lai Klang that had a little accident this summer. It was outside and - squirrels took an interest in it. Ended up, I shoved it in a short drinking glass, proceeded to neglect it, and just dumped water in the glass occasionally. Imagine my surprise when the bottom of the glass was soon covered with new, fine green roots! I continued to abuse/neglect it for a few more months. Roots stayed green and now we have aerial roots. We could call this success except there is algae growing in the glass, too. And I fear that my luck will run out if I don't do something more permanent.

I read about repotting dendrobiums. Generally, I read about pots that are smallish but deep or shallow and wide. And some articles referred to mounting dens. I happen to have a terracotta "orchid" pot, full of holes. It is 6" across but just 2" deep. I would like to use it but have concerns. The medium I have available is mostly a bark mix from rePotme. Also have leca. And I have spaghnum moss on hand. If I use the pot, do I fill it with medium? Or could I put some in the bottom of the pot and set Lai Klang in it, using it somewhat like a mount of sorts? I'm concerned that when roots are moved from the wet environment, they won't be happy. The aerials may decide to attach to the terracotta nicely..?

It has been a survivor and I'd like to give it the TLC it deserves.
