So I just built an incubator using a 120qt coleman cooler, flex watt heat tape, spyder robotics herpstat, indoor/outdoor thermometer, computer fan, and put an extra rubber seal on the inside of the lid. One question though. I have the probe in between the heat tape and the cooler, should it be on top of the heat tape and open to the inside of the cooler?(yes heat tape is inside the cooler). I'll post some pics when I get a new cord for my phone. Thanks
