humidity problems

What kind of bator is it??? do you have both red plugs open??? and on what day of bating are you on???

 

I have the opposite problem.

I live in a low, marshy area and we had torrential down-pouring rain twice last week that bumped the humidity in the house up to 69% PLUS the water I had in one of the troughs of my Brinsea Octagon 20 ECO. I sopped all the water out of the 'bator and got two dehumidifiers running in the house, but it took about four days to get the humidity back down to 55%.

Humidity has to be the single most difficult variable to control during incubation.

Just remember that to raise your humidity you want to increase the surface area, not the depth of the water. Large, shallow containers (or even cake pans) do the trick better than a cup or dish.

Good luck!

 

Have you tried to check the hygrometer for accuracy? If not, I'd recommend it. I checked a couple of mine and found each of them to be off by different percentages.

Here's a cut and paste of how to check for accuracy:

To calibrate a Hydrometer

1/2 cup of salt
1/4 cup of water
Freezer Ziploc bag
Put cup of salt water on one side of the bag Hydrometer on the other.

Wait 8-12 hours Hydrometer should read 75%

If it reads lets say 80% humidity then that means its off by 5%.

Mix the salt and water well; use a large sized Ziploc bag to the cup of salt slurry and hygrometer are separated a bit.

 

I don't know what kind of containers you're using for the water, but remember that it is surface area, not volume that increases the humidity. 2 shallow wide opening containers will put off more moisture than 2 tall skinny containers.
