I need to know the same info on humidity. I've got moldy eggs then some to dent. My temp is 75degress F and humidity about 55-65%. I just can't figure out what's going wrong. How moist should the vermiculite be? If I have about an inch and a half in a deli container how much water is needed. My vermiculite is moist to the touch but not wet feeling where you can squeeze out droplets of water.
