I read the thread. It was interesting. It sounds like he lives in the perfect climate to hatch eggs without adding water but everyone does not have that luxury. I can understand if your humidity stays at 50% in your incubator without adding water it should work fine. So it's really not dry incubatio it's don't add water unless needed to get your humidity to 50%. He also talked about getting humidity right in the incubator room. It looks to me like it would be easier to put water in the incubator than a humidifier in the room. Am i missing something? I am always trying to learn.
