   What kind of substrate are u using and what is the volume?   
      
   It depends on the insulating capacity of your substrate (large   
   wood+grain blocks or large bags of small seeds take notoriously long to   
   sterilize, pelletized substrate less so) and it also depends on how you   
   pack everything in the sterilizer. It shortens the sterilization time if   
   you keep open spaces between the bags.
