Oh I am sure the PVC is better if so many say so. But I will make a nice glass tank work well enough for me and for a baby python I hope. The black or white PVC ones will look real bad in my living room FYI. And that's where the boss says it goes for now.

So would anyone mind PM'ing me with what UTH watts/size was best on a 20 long. When I say lamp I thought a red bulb was fine? Also what Watt CHE was best between 50w to 100W? How did the percentage of humidity change with each 25 watt jump? I will try some engineering/science and good old redneck ability to one up the old glass tank. If I fail it will not be the first time. But I enjoy that type of stuff. And I learn new stuff! Extra part of the hobby to keep it interesting for me. And I can always throw in the towel and go PVC later for a larger habitat.
