Humidity Question: more frequent watering to remedy low humidity?

[TheEndPhase]

For mounted orchids requiring a higher humidity, is more frequent watering an acceptable remedy for a somewhat lower humidity than what's recommended? I've been doing that so far, but it hasn't been long enough to tell if they appreciate it or not. I do make sure the cork they're mounted on is dry, and the roots turn from green to off-white when they're dry (Aerangis punctata), so I know I'm not watering already-wet orchids - I don't want to rot them. Also, I avoid the leaves, but douse the plaque and roots. I want to know if this is ok before I run myself into trouble!

Thanks!
