I built a cabinet style incubator with two trays and a turning bar to turn the trays. I bought a thermostat/ fan from incubator warehouse and use plastic dishes in the top with humidity pads to control humidity. I also have a plexi glass center in the door. This is my first time using it and all the factors are correct. Temp is holding at 99.5, humidity with one dish and humidity pad stays around 45-50% for the first 18 days then I add second dish and pad to get to 60% for the last 3 days. My biggest problem is there is sweating towards the front of the incubator. This collects on the pelxiglass door and runs down the front and collects in the front of the incubator. I have had the incubator running for almost two month and have had two fairly successful hatches. I am noticing though that the wetness is creating mold growth in the incubator. How can I control this? Should I put some sort of sealant inside the incubator? Should I move the plastic dishes further back into the incubator so there is not so much concentration towards the front? The incubator is made from non presssure treated plywood.
