I've had my incubator running for almost 3 weeks now. I've got a test tub in there with vermiculite and water as well as an egg crate. The tub is a shoebox tub with press-n-seal on top. My humidity is still only sitting between 80%-85% despite adding more water. What should I do? Add so much water that the vermiculite can't hold anymore? I'm at a loss of how to get it to 90%-100%. Now that I've got the temps stabilized...the humidity is whacked up. I just want this sorted out before I get eggs.
