I just put together my new rubbermaid container. The holes are drilled, the decor is in, the heat pad is underneath with a slight amount of space between the pad & the container. However, I am havin a problem. It seems as though the temps are not getting to where they need to be. The temps over the heating pad are only just over 80 & the cool side is at 73. Short of actually rippin a hole in the top for a heat lamp, does anyone have any suggestions on how I can boost my temps!!??
