Winter time - balancing heat and humidity?

[QUOTE=orchidwitch;903654In the past, I've just conventionally checked the moisture of my plants (orchid or other) by touching them and adjusting based on how moist they like their soil to be.[/QUOTE]

I hope this is just a terminology issue... epiphytic orchids (which is what you're likely to be growing) don't want to grow in soil. Bark, or (loosely packed) sphagnum gives them the air, as well as moisture that they need. (They want "moist air", not "wet".)
