i figured id lay down Styrofoam on bottom for better insulation then put the egg boxes on the foam. tape the 6ft of flexwatt around the cooler. i shouldn't need bigger flexwatt as my room is heated by a radiator space heater on its own t-stat set on 84. and at 84 it keeps amb room temps around 85-86.

once the flexwatt arrives ill get it taped in and set up to see if i can maintain the temps in the room temp i have.

Well it wont laugh when its incubating as it wont be pluged in or ill have frozen eggs. if it dont hold heat in well then ill set up a igloo cooler with a poly box inside that with the flexwatt.
