How can I effectively sterilize straw for growing mushrooms?

To effectively sterilize straw for growing mushrooms, you can use a process called pasteurization. This involves soaking the straw in hot water (around 160-180F) for about an hour to kill off any harmful bacteria or fungi. Another method is to steam the straw at a high temperature (around 160-180F) for 1-2 hours. Make sure to cool the straw before using it to grow mushrooms.
