I'm a little late to this post but here's what mine look like. The humidity should be in the egg tub only and not your incubator. My incubator runs around 30% humidity but my egg tubs run 100% humidity. As you can see my substrate is soaked and even has water on top. I also want to say that my incubator is a freezer converted and has fans to circulate the air flow and contol any hot spots.
