That awesome! Great job on tinkering with the CHE. Honestly, the initial setup is the hardest thing. Sounds like you have things dialed in.
Let me know if you notice a behavior change with your BP. I'm always interested to see if their behavior changes during warmer temps. Also, be sure to keep an eye on that CHE during warmer weather since you only have it on a dimmer.
If you ever make a leap into PVC enclosures like Animal Plastics, things get even easier. You don't have to monitor temps as much and humidity stays relatively the same.
