That's one awesome incubator!

I'm thinking, maybe add a hygrometer in there just to make sure the humidity stays above 80% when the water bowl gets low. Not sure if you need a tiny fan just to move the air around to prevent hot pockets with that awesome incubator. As long as condensation doesn't form on the top of the incubator that could drop water down the eggs, I don't think you need to worry about lids until they start to pip and try to crawl out of that tub.
