incubator will be built :)

I see a lot of condensation in the tubs now :( Is there a way to get rid of this without making it unsafely humid in the incubator for the FW?

Sounds like you have the same issue I had. I assume the humidity in the egg boxes is near 100% what is the humidity in the incubator?

The only way I know how to fix it is to increase the humidity in the incubator. I only had to increase it to 50-60% and that fixed my isses which isn't an issue for the flexwatt.

You could remove some of the water bottles and put an open dish with water under the grate to increase the humidity (that is what I did)

Condensation has nothing to do with a difference in humidity between the interior of the tub and the interior of the incubator.

Temperature differences is what causes condensation to occur.

Condensation occurs on surfaces that are significantly cooler than the temperature of the air which is holding the water vapor.

Water is condensing inside the tub because it is warmer inside the egg box than inside the whole of the incubator.

I wonder what I should do to remedy this; a fan would be very hard to fit into there. Airholes?

Actually it can...while you are right for one way condenstation is created in this case it is unlikely there is that much of a temp difference between the inside/outside of the container (her last reading was only 2 degrees).

Condensation can also occur when air has reached saturation levels (like inside a sealed egg box) and it trying to equalize with the outside air (it also mostly likely means her boxes are not completely air tight). If you equalize the humidity the condensation will also lessen.

If the egg box is sealed, there's no way that the air inside the box would "try to equalize" with the air outside of it.

Condensation is affected by differences in temperature.

Equalizing the TEMPERATURE is the only way to eliminate condensation, regardless of the relative humidity inside and outside of the box.

From that same article

"or when the water vapor equilibrium in air, i. e. saturation humidity, has been exceeded. When water vapor condenses onto a surface, a net warming occurs on that surface."

This is also why I suggested the egg boxes aren't really sealed.

But I have no interest in arguing, I just wanted to help her...but be my guest since you are right.:)

I'm not trying to argue, just wanted to clear that up.

You're misinterpreting the quote above. Saturation humidity occurs when the air has absorbed all the water is can (based on the temperature of the air, warmer air can hold more water then cooler air, similar to warm water being able to dissolve more sugar) and the excess water vapor gathers on a surface. That has nothing to do with what you are saying...that a difference in humidity between the two chambers would cause condensation to occur...that's just not true.

yes it is true. Air will always try and equalize its pressure (drive partially by humidity) from an area of high consentration to one of low. Yes, if it hits a cold object water will "condense" out of the air and stick the surface...but even without a temp difference it will still "condense" while trying to equalize. This is most moticed in homes that have older windows.

As for the quote it is exactly as I am using it...the air in the boxes has reached saturation (all the moisture the air can hold - which increases the air pressure inside the box) it is now trying to equalize with the surrounding air and hence is causing condensation. I am not saying that a slight temp difference on the walls of the box hasn't caused some of what she is seeing but by increasing the humidity in the overall incubator will fix the issue.

But since we have different opinions what do you suggest to fix the issue?

She simply needs to equalize the temperatures inside and outside of the box. Those closer she gets to to that, the less condensation will take place.

I'd say to put a small 12 volt fan inside the incubator to keep the air moving around and equalize the temps.
