I started off with 250g vermiculite and 250g water miixture. When the humidity was only at 60%, I dumped about 500mL more of water (I'm estimating because I didn't actually measure it) into the egg box. That brought he humidity up some, but at the time I didn't have press-n-seal. That's when added the press-n-seal and it went up to the 80%-85%. I'll put a spare water dish in the actual incubator and see if that doesn't help some. Do you think I should just completely saturate the vermiculite? I won't have my eggs sitting on the substrate. Like I said, they will be sitting on an egg crate.
