So, I calibrated my hygrometer today using the salt test and it said it was 12% off??? This is a not-so-cheap hygrometer made for humidors...do you think this is really accurate?? I expected it to be a bit off since my last hatch was a failure....but I never expected it to be that off. I guess I took the "dry incubation" to new heights...geesh! Anyone give me insight on this test?? I'm setting eggs tomorrow...want to make sure I get the humidity right this time. Thanks!
