Bubbles, I have been using an old hovabator still air and run at 100-101 rocks or sealed containers of water help moderate temp swings, but I still see it rise to 102-103 for brief periods around the 10-14 day mark, then it seems to settle back again after an hour or so.
The older the thermostat, the more touchy they seem to be. Just my experiences, but any heat sink helps reduce fluctuations.
Good morning all!
Country, any possibility of running two timers and different lights? I run my morning light at two sixty watt bulbs that come on at 530 am, and my evening one with a 25 watt that comes on at 5 pm and turns off at 9. I get steady production from my EE's, OE's and Rocks throughout the winter with this set up. Not as good as spring and summer, but at -20 how can you blame the ladies for trying to conserve energy? Might be worth a shot with your flock
