If it's a temporary/quick fix, why not just use one of those large igloo coolers?


I did one last year for a clutch of JCP's using a medium sized igloo cooler and a no-substrate method. Used 12" flexwatt attached to a Helix, lined the bottom with water bottles, a layer of egg crate on top of the water bottles, sterilite tub on top of the egg crate, 2 layers of egg crate in the sterilite tub, filled the tub with 1/2" of water, set the eggs on the egg crate just over the water, set the Helix at 89F and waited 55 days.
