Here is a picture of my 15 quart tub setup for critique's:

I have a consistant 93-94F on the warm side (which is the bottom half of the picture) and a 79F on the cool side (the top half of the picture), running about 80-90% humidity.

Is there anyway to boost the cold side?
Is the 80-90% humidity too much?
