Hey all...quick question! I was lucky enough to pick up a large, glass front cabinet style bator at an auction. It is a GQF with two wafer thermostats (I think) and three trays. I do not believe it has an electronic thermostat. It also has a dial inside the incubator on the upper right that is labelled "relative humidity". You can turn the dial from around 30% humidity to 100% humidity. Is anyone familiar with this? I was going to order a new humidity pan and pads with the automatic waterer for the top, but I wasn't sure how this correlated with the dial inside. Any insight???
