Did you perform a salt test on your hygrometer? Super easy to do and worth it. I personally run lower than 40% first 18 days. But if your air cells are on track do what you think. I find 30% is a good incubating RH.
How I perform a salt test:
Milk or juice cap full of salt. Add drops of water while tapping side until saturated. Pour off standing water.
Put hygrometer and cap of salt into a zip seal bag, sandwich or quart size are usually handy, and wait 4 to 6 hours. I provide small pillow of air.
Take note of your reading and subtract that from 75. A salt environment will be exactly 75% in normal home temperature.
Write your calibration number on a piece of tape and stick to incubator as a reminder of your RH reading adjustment.
EX: your reading is 82%. 75-82= -7. You'd always subtract 7 from your readings to be true RH.
