Temp should be easy to keep once you find the right place to have your bator, in the house, or garage, where ever you are incubating. Humidity..makes a difference in the area that you live. I am in the desert. I have to really add water to get humidity up for lock down..don't worry too much for incubation, but keep it around high 20's and low 30's. Have to add sponges along with full wells to get to 60 .. 62%, where some, like those that live in Florida for example, have no problems getting that humidity where it needs to be lock down. May have a problem keeping it down during incubation though.
