Dendrobium 'orange gem' - conditions?
 

I recently purchased a very large dendrobium 'orange gem', on a cork mount, from a collector who is leaving town. I know he had it in a greenhouse, which I do not have. I was hoping it would be OK in my bathroom, which has a skylight. But I am worried about the humidity, even with 1-2 showers in there/day.
Would wrapping its roots w/spaghnam moss help or is it one of those that doesn't like its roots wrapped? plastic bag around the roots and mount? A humidifier?
How little light can it tolerate, and what temps? thanks, Susan
