I have a 52 quart cooler that I'm converting to an incubator. I'm going to put heat tape on the bottom and use a thermostat. My question is what goes on top of the heat tape? Can I add that egg crate/plastic light diffuser directly on top of the heat tape? Will the heat tape melt the plastic? If I can't put the plastic light diffuser on top of the heat tape, what would you recommend? My initial plan is to have heat tape on the bottom of the cooler, then the plastic light diffuser, then a layer of water bottles lying on their side, then another plastic light diffuser, then the egg boxes on top with the thermostat sensor in one of the egg boxes. That's my initial idea. I'd welcome any suggestions or input. Thanks in advance.
