How cold is too cold

[NorthernRegius]

The heat lamp has warmed it up some. The ambient temperature is 84 on the side with the heat lamp and 74 on the other. Now I'm going to have humidity problems. The humidity is already down to 45% and I'm sure it will be in the lower 30's by morning.

At least you got temps up into acceptable ranges- below 70F you risk RI. I personally don't like to see less than 72-74 if that. You can do things to bring the humidity up- misting or better yet adding a moist hide filled with organic Sphagnum moss that is kept moist.

You can add the styro-board insulation around your set-up to help insulate it, but with room temps that cool, I doubt you'll be losing the heat lamp.
