I purchased a few bales of wheat straw from my local farmers co-op. I chopped it up by running over it a number of times with a lawnmower. I then lime pasteurize it for 24 hours before inoculated it with pink oyster grain spawn and placing in a 5-gallon bucket. The wheat straw must’ve had some wheat seed in the straw for now I am having green wheat sprouts growing in my 5-gallon bucket. Any suggestions, short of steam pasteurization, as I move forward towards my next batch of 5-gallon buckets.
