Working on getting my (2) new incubators temp & humidity settings correct before my eggs arrive and I am finding that the LG still air humidity level with all water channels filled will only come up to 47%. So I guess that I will need to add additional water surface area to reach the desired 50%-60% range. The other one I bought is a Hovabator 1602N with the fan & has a lot more channels to add water & when I turned it on I just filled the center channel & it is running at constant 55% humidity from the get go. Both are holding temps well at this point. Will be using turners in both units.
