My wet bulb in the low 80's means the humidity is in the 40's on the high end so I'm right there with you. The hatch 101 article is awesome and I continue to re-read it. I have been marking the air cells and I'll know tomorrow night if I need to adjust for the last week. I agree that the hatch 101 article is completely empowering. This is only my second incubation and I feel completely in control this time, not only because of that article but because I can come here for emergency advice. I'm perpetually in awe of the Internet and how it has democratized information.
