Growing mushrooms in the home is a rewarding hobby that gives you sustenance and saves you money at the grocery store. Preparing mushrooms is not a difficult task as long as you know the materials needed and the process. It is important to follow all sterilization techniques and substrate preparation (the material the mushroom grows in) properly to ensure your mushrooms are free of contamination. Growth of mold inside the substrate can make the mushrooms dangerous to eat.
Place your vermiculite into a small, plastic bowl.
Pour room temperature water over the vermiculite, stirring the substance with a spoon. Do not flood the vermiculite.
Pour in the brown rice flour and mix it together with a spoon.
Put the vermiculite and brown flour mixture into your glass jar so that it is close to the top of the jar. Make sure that none of this substance is on the lip of the jar as this will cause the spores to grow up the side of the jar.
Place a layer of pure vermiculite on top of the mixture to prevent contamination. Fill the jar to the top.
Place aluminum foil over the glass jar to seal it.
Sterilization and Inoculation
Add one inch of water to your pressure cooker and place your jars inside the cooker filled with the substrate. Place a pressure cooker rack at the bottom to keep the jars from touching the hot cooking surface of the pressure cooker directly.
Put the lid on the cooker and allow it to cook at 15 psi for 15 minutes. Take the jars out of the cooker once it has cooled
Prepare the tip of your spore syringe (bought from a greenhouse) by holding it over an open flame to burn off contamination. Shake the syringe to break up large clumps of the spore. If you cannot shake the spore inside, draw in 1cc of air from the open flame.
Inject the spore substance from the syringe into the jar as close to the edge of the jar as possible. Place another layer of foil on top of the jar once it is filled.
Store the jars at 70 to 81 degrees F. Mushroom should sprout within five to 10 days. Allow the mushrooms to grow further by taking a large plastic bucket that is loosely sealed by a plastic bag and place a 1/2 inch layer of perlite at the bottom. Slide the substrate with the mushrooms upside down into the bucket.
