I have a home made still-air bator and am using a water heater t-stat. I have read where one person says leave the back exposed to air and another says put metal behind it. I have a mine mounted to a piece of sheetmetal and its working well. It's day 14 and I have 21 out of 24 developing well (2 weren't fertile). I am going to install a fan for my next batch and wondered if it will make a difference. If you don't "believe" in using this type of t-stat, please don"t reply with some condescending rant.
If you want to preach, go tell it on the mountain.
I just want good advise . Thanks
