Outside humidity 72% how do you lower it inside the incubator?

    I have a question, using a Hova Bator 1583 with a temp of 99.5 and no water in the channels I have a humidity of 60 percent. Eggs just started yesterday and this is the first attempt for me.
    Now air outside the house has a temperature of 72 degrees and a relative humidity of 72 percent. Of course the humidity lowers some in the house but not much. My Accurite from Lowes says that the humidity inside the home is 60 percent and that is what it is inside the incubator as well.
    So if you have that situation and happen to be trying to hatch in a monsoon somewhere, as it has been here for three weeks. Are there ways to bring down the humidity when you are starting with extremely humid air and raising the temp which allows the air to hold more moisture and incubating eggs which adds still more moisture to the air.
    Thanks in advance to the answers.

    I think the only way, short of putting a dehumidifier in your house, would be to add more ventilation to the incubator. Faster air change, would lower the humidity in the incubator, as the heated air would carry off the evaporating moisture from the eggs. Even if the RH in the house air starts off @ 60%, warming the air to 99.5*, will bring the RH in the incubator down. I think the reason your bator is @ 60%, is the evaporation from the eggs, bringing it back up, even after the air is warmed.

    I Have A Lg And Having The Same Problem Called Lg And The Lady On The Phone Said You Must Keep Water In The Incubator And That She Didnt Understand Why My Hydro Meter Is Saying It Is 46% With No Water In The Channels That My Hygromator Must Be Wrong But i Had It Calibrated At The Cigar Shop Were I purchased It But Anyway She Said To Keep The Channels Full So I am But Not 100% Sure If That Is Right

    Is it raining there or something? 72% outdoor humidity is pretty high. If that is correct it won't stay there. I'd just wait it out. In a day or 2 (or whenever your rainstorm goes away should that be the case) then it should go back down. A day or 2 of high humidity at this point won't harm the eggs.

    Well thanks for all the replies. I sort of mispoke in the orginal post, I meant to say you start with 72 Relative humidity and then hot air holds more moisture so the R/H drops but then the eggs add still more moisture. And yes it has been raining nearly a little every day for three weeks. We have made the national news here in OK because of the flooding etc. I know that the humidity will fall eventually but there is rain in the forcast for at least a few more days and that is what started me thinking about this. More curious than anything as I began to think of people that try this say in Hawaii where the humidity can stay high all the time etc. Heating the air will bring it down some and here the humidity is rarely this high for this long so it should not be a continuous problem. Again thanks for the quick help.
