I followed the advice here and went with a tub over a tank. I'm finding that just 1 warm hide regulated by a thermostat/UTH is not enough. The cool side just reflects room temp which is 74 and too low. So I'm wanting to know what my options are and what most people are doing in my situation.

I can't decide if I wanna heat the entire room (expensive), or if I wanna buy a 2nd UTH / thermostat (also expensive), or if I wanna go back to a tank / light setup, or if I just wanna forget perfection and let the cool side stay 74 year round with 90 on the warm end.
