Just an update on the hygrometer calibration today.
I've had it in the ziploc bag w/ the salt water just as suggested by Jimnjay for exactly 9 hours and it's reading 73%.
So, it's nice to know its reading only 2% off. Thanks for the great link Jimjay!
Will have my coffee can candler ready to check the eggs for development this weekend.
I will let you all know what I see.
Again, thanks so much for the help!
