My jars are beginning to get white on spots on the sides after 1 week .How do you know when they are 100% colonized? When ready to put in FC does the perlite have to de sterilized? Boatman
100% colonization willbe when the whole jar is white(minus the verm top layer. Then be sure to let it go one more week. Some people sterilize the perlite. I don't. I do spray a little hydogen peroxide on it before I put my cakes in. Just don"t spray that shit on yur cakes.
