HO'k, we're still at it.

Problem:
Cool side's too cool, hot side's too hot. Humidity I can usually keep up with (Florida does have an abundance of it).

Set-up:
30 gal breeder w. sliding screen lid, aspen and cypress mixed bedding, about an inch in thickness. I'm about to put newspaper back under it and maybe add another inch or so of substrate.

A Heatwave large UTH (though, I think it may be desert ... will this make a difference even though its controlled with:
http://www.herpsupplies.com/product.cfm?id=SZMRT10 ??) on the middle right, large water bowl in back right corner (gets about 1/4 of the UTH)

Occasionally I'll have the heat lamp on ( http://www.thatpetplace.com/Products.../Itemdy00.aspx w. dome) to help keep the COOL side warm enough. The rheostat is set to as LOW as it will go and still my temps want to creep up past 95. Probe is under hot side hide so I'll lift the hide to cool it off or occasionally turn the whole thing off.

Opinions wanted:
I'm planning on building a cardboard/ducttape/tinfoil cover for the majority of the screen lid, since I've read a lot of posters saying it helps keep the humidity up, but what about regulating heat?!?

Will it help circulate the ambient temps better? Will I need to get another UTH and dimmer for the cool side? Are there other options I should consider, such as layering different substrates, etc.? It's nothing so extreme as to affect his health/eating...just bugging me as I'd like him to have the perfect setup I dont have to constantly adjust.

Don't say plastic tub, I like the $80 tank I just bought. Just trying to work out a few kinks in the system. I know other glass tanks have been accurately set-up, so glass tank related suggestions only please!

Thanks!
