Incubator - 99% Humidity

[MasonC2K]

Hi all,

I've been test running my incubator for a few days now. And I may or may not have a humidity problem.

I am using a 150 qt cooler and I am going substrateless. Without any water in the cooler, I am getting ambient humidity around 60% at 88 degrees. When I add water, I am getting 99% humidity at 88 degrees. Water is condensing on the inside of the cooler lid and on the sides. My instinct tells me this is too much. I could be wrong though. Please advise.

If this is bad as I expect, I could use some suggestions. I don't think it's the amount of water but perhaps its relative distance from the heat source?

Thanks.
