How do I Grow Mushrooms on Wheat?

Sterilize the mason jars in a pressure cooker according to the cooker's directions. Remember never to run the pressure cooker dry when sterilizing jars, says the Shroomery. Cool the jars on a towel for about 10 to 12 hours so they are at room temperature.

Pour the wheat grains into the jars until they are half full. Put on the lids.

Poke four to five holes through the lid with the syringe (use a safety pin if there is too much resistance with the syringe needle). Thread some of the polyfill onto the syringe needle and poke it through the hole so it is halfway through. The polyfill blocks contaminants and can be as simple as cotton from a crafts store.

Sterilize the syringe needle with the lighter for about 10 seconds, then swipe it with a cotton ball soaked in rubbing alcohol. Carefully insert the spore syringe through the lid holes and inject 100 cc of the spores into the wheat. Repeat this through every lid hole, sterilizing in between each injection. Place the jars in a cool dry location that is about 85-88 degrees Fahrenheit, using the heating pad underneath the jars if necessary.

Keep an eye on the jars in this location until you observe a white fuzzy material starting to grow, also called mycelium.

Observe the mycelium until it has completely covered the wheat substrate, forming a solid patty.

Add a layer of perlite to the bottom of the plastic container, which should be about 12-by-12 inches. Open the mason jar and slide the "patty" onto the perlite. Close the lid and keep the container in the same location as you kept the jars. Every day, open the plastic container and fan the mycelium with the lid about three times.

Pick the mushrooms once they are at the desired size. They are technically good for harvest when the cap has separated from the stem all around the edges. On average, mushrooms are ready for harvest anywhere from a few weeks to a little over a month. This, of course, depends on the variety, as well as how large you want the mushroom to grow.
