Things Needed
Growing mushrooms indoors may seem like a mysterious practice , but it is rather simple when done with the right materials . mushroom want a substrate to grow upon , such as rice , woodwind or spent barley . The substrate makes a tender , moist , decaying medium ideal for mushroom growth . Mushrooms spores can be purchased from a variety of retailers . Barley is used in the yield of beer . spend barley can be hold by local microbreweries or home plate brewers . They ’re often glad to get disembarrass of the stuff . Once the spores are placed in the slowly decaying barley , the fungi will get eatable mushroom-shaped cloud cap . Shitake and oyster mushroom grow well in spent barley .
Preparing the mix
Step 1
Fill a arena with 140 ml of vermiculite , 40 ml of spend barleycorn and slowly pour water into it while stirring with a spoon . Only put in enough water to slightly drizzle the mixture .
Step 2
Fill the half - dry pint jar with the mixture and top off the jar with a small amount of dry vermiculite .
Step 3
shoes three layers of transparency over the top of the jar .
Sterilization
Pour 1 inch of body of water into the bottom of your pressure cooker and place a single-foot at the bottom of the cooker .
direct the jar with the mixture in it onto the rack inside the press cooker and seal the lid .
Warm the pressure cooker slowly , over a time catamenia of 15 minutes , until the pressure is 15 pounds per square inch . Leave the shock in the cooker for 45 minutes .

Step 4
move out the jounce from the cooker and countenance to cool for five hours . The high-pitched heat from the pressure cooker will have sterilized the spent - barley potpourri
Innoculation
Shake the spore syringe to break up the spore within .
Heat the tip of the syringe with the lighter so that it is shine . That sterilizes the tip . admit it to chill before using .
Lift the top two layers of foil off of the jar and stick the syringe through the stay piece . Slowly put in the spores into the mixture . supervene upon the foil .
invest the jarful in an area that remains between 70 to 81 degrees Fahrenheit . You will see sprouting inside the shock after three to five days . This sprouting is the mycelium .
Step 5
Place the mental object of the jar inside of an sure-enough fish cooler or plastic bucketful after the jar has begun showing signs of small pin head mushroom cloud get , which should begin between five and 10 Clarence Shepard Day Jr. of inoculation . This means the mycelium is ready to fruit . Cover the old fish cooler or credit card bucket with a moldable base to prevent change in humidness until the mushroom are ready to harvest .
Warning
If the mycelium inside the jar appears any other colour than ashen , then the medium is contaminated and all must be discarded .
