Undertank Heater on Melamine?? Ideas?

Check out the other post I made... Its here: http://ball-pythons.net/forums/showt...ase-Read/page2 -- I also already used wrap for the top to keep the heat in & humidity. Altho, I think I am now going to go with a cornsnake... I tried raising humidity and even with 2 water bowls in there I could only get it to 50%. My question is did I just waste $10 on 4x4's that will raise the tank too much and not heat the bottom. Im 100% going with a cornsnake. The warm side temps were 85-90 & cool side was 75... I think those are pretty good. Hides on both ends.... then I have a 150 watt heat bulb for night.

So you think the 4X4's will be too much air? I dont really want to order another heating pad, I just bought the Zoomed 8x8 off ebay for $25....

If I have to should I order this: http://www.bigappleherp.com/Intellit...2&category=14#

Your able to place it inside the cage and I have a rheostat to control temp and temp gun.
