We are often asked; can we use sawdust as a substrate to grow mushrooms – yes you can , BUT we don’t recommend pine sawdust.

Another one is ” Wheat straw or sorghum seeds?” Our answer is wheat straw. :) If you are going to use a lime soak method to sterilize your substrate then there is no need to add anything to wheat straw. If you are using a heat method, then add a supplement of bran/maize.
