air exchange. This method works fine under sterile conditions although the degree of filtration is not

guaranteed. The best combination uses filter discs in conjunction with one piece screw top lids
having a %-½ inch diameter hole drilled into its center and fitting a narrow mouthed autoclavable
container. The authors personally find the regular mouthed ½ gallon mason jar to be ideal. (Note:
These ½ gallon jars are inoculated from quart masters, a technique soon to be discussed). Using
only filter discs on wide mouth jars is not recommended due to the excessive evaporation from the
grain medium.
To produce grain spawn of 48-52% moisture use the formulas outlined below and autoclave in
a pressure cooker for 1 hour at 15-18 psi. Note that considerable variation exists between measuring cups, differing as much as 1 0% in their volumes. Check the measuring cup with a graduated
cylinder. Once standardized, fashion a "grain scoop" and a "water scoop" from a plastic container
to the proportions specified below.
