The folks that gave it to me have theirs growing in a 12 in. pot in moss. It's in a Greenhouse tho, so get's an even watering pattern. Because my greenhouse can get rather warm in summer I tend to move almost everything outside. I have had them in a small plastic pot with loosely packed moss while deciding how I wanted to proceed with it. In the meantime , one of them has started growing two new bulbs. My only concern with mounting is attaching. The roots are so fine, I'd have to pad them carefully with coco fiber and probably some moss also to keep them from drying out to fast. Most of mounted ones have to be watered daily or darn close to daily to keep them from drying out to fast in the summer.
I may have time this afternoon to fiddle with it a bit. As far as being moved, repotted are they that fussy ? ( didn't seem to bother them when plucked from the mother plant), I was thinking I might let them grow in the basket awhile till they got a little bigger then mount.
