Hi all, this is my first post here

I recently got a male BP 4 days ago, and I'm having trouble figuring out the heating aspect of things. I've got a zoo-med UTH under one side of the tank, and an overhead red heat bulb up top. I'm having a really tough time keeping temps up, while still keeping acceptable humidity. I've got about 80% of the top of the glass tank covered in 3 layers of tin foil, and packing tape on top to seal it up. There's a square cut out where the heat lamp is, as well. Looks pretty similar to the glass tank setup in the sticky thread.

I've also made the homemade humidifier, and it's doing it's job to an extent - raising the humidity to 52% on the cool side, which is currently sitting at around 78-80 degrees. I know this is a bit low, but if i put another light on the cool side turned down to the lowest, it heats up to about 85 degrees and sucks the humidity right back out of the tank.

Now, unfortunately, the only place I can put the tank is up in my room, in which ambient temps can get around 66 degrees when its below freezing outside.

I've got a zoo-med UTH on one side of the tank, but i can't see how this could possibly warm the entire tank up. It's hot and all, but the surface of the inside is warm at best. Could my substrate be too thick? Does newspaper-only bottoms heat better than thicker substrate? (it's 1" thick approximately.)

If i could get it to where i used only the UTH, i would imagine keeping the humidity at acceptable levels would be much easier. Or should i just scrap the glass tank in favor of a tub?

Also, I have a Herpstat ND thermostat in-transit being shipped here. Should I invest in flexwatt instead of this seemingly-useless zoo-med UTH?

Thanks! And by the way, this is a great site, I love it!
