Thank you all for looking and your nice comments. To answer Bud, unfortunately it's not a silk curtain but a nylon one

in the summer months I double the curtains as otherwise the sun is too strong.
Matt, I tried all sorts of mediums/pots to revive her and she happened to take to this mount which is hollowed. When I first put her there there was alot more sphag & I noticed the roots were rotting again so I removed a lot of the moss, she's been in the enclosed glass since August and seems to love it. I can't tell you if they do better mounted as it depends on the growing conditions you have. Mine has certainly done better.
