I got the 15 dollar hovabator holding a nice steady 100 degrees. Cost me a $6.99 wafer for the thermostat. I'm adding a fan also. Fan was free. It runs off of 24V, but I have a transformer. I'm ready to hatch, with the exception of one thing. I need to clean the bottom part of the bator. Apparently they never used a liner in it. I can make my own liner. Not worried about that. I just need to know what is going to clean and sterilize that foam. Thanks in advance. This is a great forum. I'm a moderator of the religious section on a harley forum that has 50,000+ members. I know what it takes behind the scenes to do this and make it work. You guys are doing a great job.
