i just bought a pm herps cage "plastic cage" (( 36" x 24" X 12)) now i put an under tank heater in there and my ball stays in his hide constantly i dont think he gets enough heat in there and i live in jersey and its cold... like really cold and my room is kinda cold.

now should i put a heat light inside the tank ive seen a beardie breeder do it but the cages were a little taller. so should please help.
