Thanks for the link! I'm still reading it.

Drying out the room shouldn't be a problem. I had to make over 75 holes (I stopped counting) holes in the tubs to keep the humidity down. Even now it's at 60-70%. Bringing the humidity down would be AWESOME for when I upgrade the tub sizes so I don't have to make so many holes again. And before anyone asks, I use a digital hygrometer so it should be accurate.

For the thermostat, could I plug it into the one I'm using to regulate the UTH or do I need to buy a new one and set it at 80-82? I ask in case it's just a precaution if it starts malfunctioning and gets really, really hot.
