Ok, I have recycled a sportsman incubator for a small rack system. I removed the incubating trays and replaced with multiple plastic bins. I have it set up now and running. The temp is at 89 degrees and humidity is at 58%. I've put the humidity and temp gauge in each tub and it is even throughout. It is forced air but the air will stay moist and it will constantly pull in fresh air. Being new to this, I was curious if anyone could tell me any problems I may have with this setup. Thanks in advance.
