I'm using a wet-bulb thermometer to measure humidity in my homemade incubator. I've used this method before with no problems, but this time it's acting wierd. I have the water dish inside the bator, just like before, but the humidity is way too high. I can't get it below 60%. Is it possible to get an accurate reading if I put the water dish OUTSIDE the bator with the thermometer inside? I can run the wick through a ventilation hole.... Opinions?
