Yes, we started testing "tyndallization" (pasteurisation, then wait 24
hours and then repeat pasteurisation) on bags with mixture of alder
sawdust and alder chips. We followed a Paul Stamet recipe and added
bran and gypsum (which we sterilized in a pressure cooker) at the same
time as adding the shiitake mycelium. This was 5 weeks ago and we are
already having mushrooms on the first bags . The bags look very well.
We are continuing experimenting with this.
