How to Sterilize Grain Spawn With Pressure Cooker

If you’re looking to sterilize grain spawn, one of the most effective methods is to use a pressure cooker. Here’s a step-by-step guide on how to do it: 1. Start by soaking your grains in water for 12-24 hours.

This will help to soften them and make them more receptive to the heat. 2. Drain the water and add the grains to your pressure cooker. Add enough water to cover the grains, and then some – you don’t want the water level to be too low, as this could lead to scorching.

3. Place the lid on your pressure cooker and set it to cook at 15 PSI (pounds per square inch). Cook for 30 minutes at this pressure. 4. Once the time is up, turn off the heat and allow the pressure cooker to cool down naturally – do not open the lid while there is still steam inside, as this could lead to burns.

Once cooled, open the lid and drain off any excess water.
