Materials Needed
- Grain (rye grain works best, however wheat grain
has also worked). Grain needs to be fresh and dried. It can be purchased
at health food stores and must contain no fungicides. Approximately 8
ounces of grain for each quart jar will be required
- Seven ounces of bottled water for each quart
jar.
- Quart Mason jars, the number needed will be
determined by the amount of mushroom desired.
- Pressure cooker.
- Screwdriver and Hammer
- Cotton Balls
- Aluminum foil
Procedure
- To a one-quart Mason jar add 8 ounces of grain, 7
ounces of bottled water.
- You will need to punch a hole in the top of the
lid, do this with the screwdriver and the hammer.
- Now fill the hole with a cotton ball, this process
allows for air exchange, without allowing harmful bacteria into the
jar.
- Place the lid on the Mason jar, and screw the lid
down.
- Shake the bottle to mix the grain and
water
- Cover the jar with a piece of aluminum foil, this
will collect any dust that may collect on top of the lid and can then be
discarded later without allowing the contaminants to enter the
jars.
- Allow the mixture to set overnight
- Place the jars in the pressure cooker and cook for
one hour at 15 p.s.i.
- Allow jars to cool and set overnight. Shake the
jars to break up any clumps of grain then recook them at 15 p.s.i. for
another hour.
- Jars need to be shaken again, then they will be
ready for inoculation with mycelium from culture
plates.
IT IS RECOMMENDED THAT ANYTIME THE JARS ARE NOT
IN DIRECT USE, THEY BE COVERED WITH
FOIL
