Here in Georgia it is hot and humid. Three of us got together to purchase our vermiculite. All three of us have had a light green mold to start on the eggs and soon after the eggs have turned dark yellow brown and died out. Two use commercial incubators while the other uses a converted upright freezer. Is there a way to sterilize or disinfect perlite and or vermiculite?
