Hi all! This is a great, and very interesting thread. Regarding the mass sterilization of wood chips, I wanted to share a method I learned from Mr. Stamets. His method is to submerge the wood chips in water for a week or so, until fully colonized by anaerobic bacterial (let your nose be your guide). Next, the wood chips are dumped onto a tarp, and spread out in a single layer (good airflow around the chips) to dry. This oxygen-sterilizes the wood chips by killing off the anaerobic bacteria. Stamets said that the chips should stay sterile enough for use for up to two weeks.
Thanks for all the great information!
