I made a large cabinet style incubator. Using a GQF wafer thermostat. Spent a few days adjusting the temps and I noticed slight adjustments either up or down caused a little more fluctuation than I am comfortable with. But I have discovered that my incubator has a "sweet spot" I guess you would call it. It is super stable at 98.5 degrees. Fluctuates from 98.2 to 98.7. Will this be enough of a low.temp to affect hatch?
