i can not get the humidity above 52% (today is day 18). i have a 9 x 12 baking pan in the bottom of my homemade incubator which is filled with terracotta rubble (an attempt to increase surface area) and of course water. the pan covers about 35% of the floor. i just installed a rolled up rag on top of the pan, so water that is added has to filter down into the pan (saturating the rag) and the corner of teh rag is in the water pan. but still, i can not get it above 52%. looking for tips/tricks. thanks.
