I had success with bringing down humidity by "toasting" sponges in the toaster oven until they are really dry and placing them in the incubator. I cut them into three pieces. It kept the humidity between 25 and 35%, they have to be switched out often (for me about every 2 hours) probably depends on your incubator and other ambient factors. You may have to do a little trial and error to see what works for you. I wrote a detailed post about it in the May hatch along. I will see if I can find it!It’s not working. Anything else I can try? 40% now
