I built me a rack tonight!

Thanks for the worries. The wood is not stained or sealed, the tubs do have holes melted into them every 2 inches or so with a soldering iron. I live in Houston where the relative humidity INDOORS is already pretty high and since I used a hardwood (birch) the likeliness that it would warp just sitting there here in my AC'ed living room (73ish degrees) is highly unlikely. The flexxwatt is doing a good job keeping the tubs warm on the one side. Amazing how such a thin and basic material can get that warm!

This is actually what I was wondering about. With the flexwatt not actually under the tubs do you still get high enough warm side temps? How high do you have to crank the thermostat to get it warm enough?

That seemed odd to me too, mine have it under tubs for belly heat.
