I have two different set ups going now and they are both perfect in husbandry. First my glass tank. I have a heat lamp on a dimmer switch and UTH on a dimmer. There are both around 50% power. This makes my ambient at 80 degrees and my hot spot is between 90-92. It will drop to 90 at night. The humidity was at 40 so I made a humidity box and got a mister and now it goes between 50 and 55.

Now my other is a tub. I bought a deep tub and I do use a 50w heat lamp on it and it is as well plugged into a dimmer. (I have not had a problem with the heat lamp on plastic at all. I also put wood over with a hole cutout for the lamp. I also have a UTH. This keeps my hot spot between 90-92 and ambient around 80. The humidity is at 55 without any other methods!
