Thanks all for the info! That clears that issue up for me then. Still, that means I'm watering 4-6 times a day. It's not even below freezing any more outside, I have a humidity tray below the plaques with a couple other orchids around it, and it's even rained for two days now, but it still seems to dry very quickly - is that a characteristic of cork?
... It's good to know I'm not over-watering regardless, though. Thanks again!
