Hello Mr. Guy:
You sound like a natural born orchid fanatic ; -)
The pink blossom in your photo looks like a Dendrobium nobile hybrid - there are so many it's tough to pin it down. They are a hardy group. I have one that is not mounted on anything, just hung up by a wire and it grows regardless!
On the mount in the photo, the only thing I think may be a problem is that it is a punky piece of wood. The Catts mounted seem to have hard wood that is not decaying quite yet. They look quite happy, so you had a good instinct for what they like. In the past when I've chosen wood that is too punky or deteriorating, the roots of the orchid seem to reject clinging to it and simply stall. Then, I've taken the plant off the mount and found a harder, fresher piece of wood or potted it. If the plantlet is happy on its wood, the roots will begin to cling within a couple of months and eventually you can take off the twine, or just let the twine rot off.
Good luck with your new hobby ; -)
Cheers
Maryanne
