Just a bit of info for people new to incubating, like myself. While the cheap Wal-Mart "Springfield PreciseTemp Digital Thermometer/Hygrometer" seems appealing, it must be calibrated first. If you didn't happen to look at the back of the package before buying, it is listed as being +/- 5 degrees and +/- 10% humidity. Took me forever to get it set right, then I noticed the packaging.
