I am also a new keeper of WTF "Bubba"
So far I only have one and I have a 18X18X24 exo-terra and love it.
I use both a infra red bulb and a 100W ceramic heater.
I also use a Zoomed repti-foger.
and all of the above is controlled by a hygrotherm HT-10 controller.
I started bowl feeding him a few weeks ago and it works great. I have a 3 inch diameter pyrex clear glass bowl.
that I place crickets in at night fall every other day 4 to 5 medium crickets and he cleans the bowl before the AM.

At the moment the substrate I have is paper towels. I change them out ever other day and if he
soils them.
I plan on getting the EXO-terra moss mats that are washable.
