Ok I have spent the past four days searching the web, and I amm still confused , I read that some dont add water at all and some add water but they dont really state what the actual % is inside the incubator,,I understand room, ambient temp,region, placement, but what is the acutal % humidtity for dry hatch ,25% 30% 50%75% 0% 10% And how low is too low , I have a Brower 846 round metal still air ,and WOW does it hold things steady, I plugged it in for a couple days and played with it 101 even and constant 25% humidity with NO water at all [no eggs yet]! thanks for all the advise
