I have my homemade incubator and hatcher in the a walk in closet in our finished basement. As stated above, the Humidity and temperature stays consistenet in the basement and the humidity is naturally higher becasue it is the basement. Also in the closet, so that it is not affected by sun light. I have a nightlight installed in both the incubator and hatcher that is on all the time, so that I can view them any time I want.
