taking water out is not what would reduce your hum%.. You have to reduce the amount/area of water exposed..
a fan would not reduce your hum% either..
I highly doubt that you have 100% humidity..
especially if you cannot get your temp higher..
You HAVE to know somebody close with a tried and true incubator..
keep building yours, but keep looking for a friend or at this point, even an enemy, with a good incubator..
