NEW OYSTER SUBSTRATE BLEND, Pushing Yields with Pasteurization

Trying to push the yield envelope with pasteurized substrate by experimenting with different substrate mixes and supplements. My goal is to develop commercially viable substrates while avoiding bulk sterilization. In this experiment, I'm using buckwheat hulls blended with hardwood fuel pellets. I have a buckwheat mill nearby, and the hulls are a byproduct I can purchase pretty inexpensively. So far, the yields with my ostreatus strains have been impressive, reaching around 145% BE in three flushes on my best yielding blocks. I plan to experiment with different strains as well as hull/HWFP ratios in the future.
