So...right now I have my ball python in a 5g glass tank with a heat lamp, and it's just not working for me. So I'm going to get a plastic tub.

My ball python is about ~2', so I thought a 15/16/17qt plastic tub would be best.

Here are the supplies I have on-hand:

-Aspen Bedding
-2 Hides (going to get another because it outgrew one)
-water bowl
-Generic aesthetic plastic vines
-Rheostat
-Home-made humidifier (but hopefully I won't need this anymore)
-Thermometer with probe; thermometer-hygrometer combo
-Heat Lamp (which hopefully I won't need anymore either)

Shopping List:
-1 Bigger Hide
-Appropriately sized UTH*
-15/16/17qt Plastic Tub

*The only question I have is the size of the UTH. Should I get one that's for like a 20 gallon tank? Or 30? It's suppose to be 1/3 to 1/2, but I don't know how I'm suppose to estimate that with the UTH when I don't have them, so I was wondering if perhaps someone could help me with that? I was going to get a ZooMed one, so if you could give me suggestions in terms of their size it would be great...

...or any other advice/suggestions/help/comments, for that matter. :-)
