Humidity control

[Paddyl]

I recently got my small incubator and have been having it go from 45% to below 25% humidity through a period of 2 days. Should I be worried about it reaching 25% humidity. Should I put more water. My humidity reader is brand new so I’d assume it would measure accurately. Any help is appreciated!

Never assume anything with a hygrometer. It is easy enough to do a salt test. Check out @WVduckchick 's Incubation Humidity article.

I tried the salt test and the results concern me more. Now incubator reads 85% meaning that it is high by 10%. Does that mean that my incubator could be at 15%?

If you do the salt test with sodium chloride, the hygrometer should read 75% if it is reading correctly. If your hygrometer instead reads 85%, yes it is reading 10 points high. So when your hygrometer is showing 85% it means the actual reading is 75%.

It does not necessarily mean that because it is reading 25% that the actual humidity is 15%. To know how it is reading in the lower range, you need to use magnesium chloride which should produce a reading of 33%. Magnesium chloride is often sold as Ice Melt.
