Maybe I'm using the wrong word... I looked for that thread for hydrometers and can't find it. I've got a large redwood chest incubator. I'll be setting 24+ EE eggs this week and I want to double check the humidity. It's got an original Taylor Wet Bulb inside it, that's screwed tight to the temp/hydro frame. You can see it here , even though it's a crappy picture. How's it possible to make sure it's accurate? Or should I just go ahead and grab a cheapy hydrometer from the petshop? Anyone? Thanks in advance.
