Thanks for all the quick replies! I can't believe I missed that part about the night drop and breeding. So I am planning on getting one of the on/off thermostats from Matt. I'm still a little confused about the temperature reading. Do the temp. probes plug directly into thermostat, then it adjusts accordingly, or do you get the reading from the temp gauges then adjust the thermostat manually? Also if the the cool side is too warm, but the hot side is just right, how can that be adjusted? Thanks again. I hope I'm not asking too much.
