A sterilized bag of Master's Mix is a nutrient-rich, fully sterilized substrate made from hardwood sawdust and soy hulls, designed to be inoculated directly with colonized grain spawn in a sterile environment. Unlike Coir based bulk substrate like our Select Bulk Casing, which are used in non-sterile conditions as a mix in a tub or top casing layer, Master's Mix is not meant to be exposed to open air or mixed in unsterile tubs. Doing so increases the risk of contamination and defeats the purpose of sterilization. Instead, add your grain spawn directly into the sealed bag using a sterile technique, allow full colonization, and then fruit the mushrooms by cutting open the bag or transferring the colonized block to a clean fruiting chamber.
