| Well, for my part, I was always excited when I got plants from the south american vendors and they had some live moss on. I eventually had quite a crop of live moss in the wardian case, so many of the mounts had no need to replace moss, as it was growing gangbusters, too. I suppose one could just slap some more moss on with a bit of nylon, if necessary. I highly recommend treefern slabs for Masdevallias, as they provide a naturally moisture-retentive quality and lots of space for roots to wander around inside the mount, itself.
