Beside this, how do you sterilize a substrate bag?

Roll down the autoclave bag about 10 cm and pour in 2.7 kg of the grain substrate mixture. Be careful not to spill any substrate on the upper regions of the bag (in case you did, clean the bag with a wet piece of cloth). Then wrap the bag twice. A pressure cooker is used for the sterilising process.

Similarly, how do you sterilize sawdust? Let the wood chips soak in cold water overnight (12-18h). Use as much water until all the chips are floating. Put the soaked wood chips in to a sieve and let drain for around 15 minutes. In the meantime put all dry ingredients (sawdust, rye brain and gypsum) into the mixing container and mix very well.

Keeping this in consideration, how do you sterilize a substrate without a pressure cooker?

If you have a pot, layer mason jar rims at the bottom to elevate the jars, add a layer of tin foil underneath the jars and fill a couple inches with water. Boil lid on for two hours. That's the best you'll get without a pressure cooker, and it did the trick before I invested in one.

How do you sterilize a mushroom substrate in a pressure cooker?

Use anti bacterial soap or better fill the PC up with some water and let it cook under pressure for 15-20 minutes. This will clean the PC for sure. 1) Fill the pressure cooker with 1 inch or 2,5 cm of cold water. Make sure there is enough water in the PC that the PC doesn't run dry during the process.
