very impressive rig Joe!

something wrong was bound to happen w/ your first attempt w/ the open containers. if it didn't leak, there woulda been a small flood as soon as u opened the incubator door.

i did a trial run w/ plastic wrap on egg boxes and i still got condensation. worse, it gravitated towards the middle and didn't drip down the sides. maybe i did it wrong or using the wrong stuff; i know some use Press 'N Seal. i don't think i wrapped the plastic flat enough causing the center to be concave causing condensation to move towards the middle. need better practice i guess.

how often do u anticipate refilling the 2 water containers at the bottom? i think u should rig it to auto-fill w/ water from a standing tank!
