Boy, if you ever need any wine corks, I have hundreds of them. I don't know about whether they make good mounts. I have a huge natural cork slab that has a dozen Florida native tillandia mounted. I simply fill the sink, and its a large one, and then put that slab upside down in the water. I let it soak for about 10 minutes and then hang it back up. That's my winter watering, Cameron.
What sort of air movement do you have in place?
