That's really cool, they look fabulous. I just wondered if the roots could attach to the smooth surface, I guess so. I've tried driftwood a couple of times and the orchids have not done that well. Of course, I'm not great with orchids anyway even though they grow wild here. I generally put the piece of wood in the swimming pool for a week or so to kill whatever is in it and get rid of the salt and then in my pond for another week or two to get the chlorine out. I think I just don't attach them to the wood well enough or perhaps I'm not watering them enough.
Anyway, good work, they look fabulous.
