If your daytime temps are that low, what are your nighttime temps? I would get those temps up a bit. 92-94 warm side....82-84 cool side. The enclosure should never get below 75 deg. Also, just to keep a more constant temp level in the enclosure, you might want to use a black/red/blue light or a ceramic heat emitter instead of the current light. That way you can leave it on 24/7 and you will not have the temp fluctuations due to the light being turned off at night.

And I didn't see a digital thermometer/hygrometer....I would suggest getting one of those too. You can monitor temps and humidity much better with that....and they are only about 14.00 at walmart.

You said dont hold back

ha...other than that I really like the setup
