Our oats and oat millet mix grain spawn is sterilized at 17 psi to kill any pathogens that may be present.   Our grain spawn is soaked in gypsum water for 24 hours and then boiled to where they are plump and hydrated before bursting (or very little or less than 5% but closer to 0%) and then dried.  What makes our product different is that they are impulse sealed BEFORE going in the autoclave which has an intermittent automatic pressure release while sterilizing.  The bags are purged of air before sealing and heat resistant tape is used to secure the bag from flapping anywhere.  The myth of exploding bags is just that, a myth if done expertly and stacked with the filter patch up in offset rows so gas and steam is released through the filter.  We also add a little vermiculite to the bottom of each grain spawn bag which most manufacturers do not do.  Experience has shown us that if you add a little too much liquid culture or the conditions aren’t perfect for storage, it helps absorb excess water without affecting the mycelial growth and cuts down on bacterial contamination.

Note: This technique is not recommended with most home stove top sterilizers, nor in autoclaves unless proper technique has been taught or your bags will explode.  This method prevents the bags from “sucking in contaminated air” when sealing or when removed from the autoclave which is one of the main causes of bacterial contamination.  It is also recommended that when you flex the gussets to allow some air in during inoculation that you do so in front of a laminar flow hood to prevent the introduction of any contaminants.
