"Put a sock in it" takes on a whole new meaning. At 99.5 degrees I was having trouble obtaining 80 % RH till I came up with this idea. Used an old sock to dip into the humidifier pan as a wick then put the other end over and around the circulation fan. The results were all I could hope for. Now maintaining an 80% RH for the final few days is a foregone conclusion. I will keep experimenting till the eggs arrive, but I now know that I can obtain optimal conditions. Here's a pic incase my explanation is lacking on how the goal was obtained.
