I just came across that link this morning actually and was considering it.

To answer your questions; I do not currently have a thermostat attached to the UTH or the overhead lamps.
Looks like I'll add that to my shopping list for this afternoon.

Right now I have a thermometer on the hot side and the cold side, and a hydrometer in the middle of the tank.
However, I was not aware that these are practically useless I suppose I'll have to drop the extra cash for digitals in addition to a matching hide(s).

Would you recommend I transfer her into a tub then?
Or would trying to adjust the habitat set-up be more efficient?

Thanks so much!
I really want to do the right thing here.
