Mine is mounted on tree fern and I have had it just short of a year. It grows roots all the time. I keep it wet almost all the time. Not sopping but if I find it dry, I water it. Mine is in bud again. It will be the 3rd time blooming since I have had it. It also hangs in an orchidarium which is in the 80- 90% humidity range.
Yours does look somewhat dehydrated to me.
I'd be happy to post an image of mine here, with your permission. I don't want to hijack the thread.
