Is Growing Reishi Mushrooms Worth It?

Growing Reishi mushrooms is very easy. They are fast to colonize and are also resistant to many contaminations. The process also does not require expensive materials or complicated procedures.

Materials needed:

  • Reishi spawn
  • Substrate (50% coarse plus 50% fine hardwood sawdust)
  • Large bucket
  • Boiling water
  • Plastic wrap% gypsum and calcium carbonate (optional)
  • When placed in the bucket, the substrate should be between 150 to 300 mm deep
  • The spawn should be around 2% of the substrate

5 Easy Steps to Growing Reishi Mushrooms:

  • 1. Pasteurizing the substrate
  • 2. Spawning the substrate
  • 3. Waiting time
  • 4. Fruiting
  • 5. Harvesting

1. Pasteurizing the substrate


The substrate is where you will be growing Reishi mushrooms. Ideally, it should be a mixture of fine and coarse hardwood sawdust evenly mixed. The best to use is oak sawdust. To produce higher yield, some growers add about 2% gypsum and calcium carbonate to the mixture.

Once you have the substrate ready, put them in a large bucket or bag and mix them well. Don’t fill the bucket to the full. Leave adequate space where you can drill small holes. Add on boiling water enough to submerge the substrate. Leave it for about 2 hours, then drain. Make sure there is no excess water on the substrate. Even small amount of water promotes the growth of mold and other contaminants.

2. Spawning the Substrate


After draining the excess water, leave the substrate for up to 8 hours to cool. Make sure that it is fully covered to prevent exposure from contaminants. It is important that the substrate is cool before inoculation. The warm substrate will kill mushroom spawn. The ideal temperature is below 35°C.

When the substrate already cooled off, mix the spawn in the substrate thoroughly.

3. Waiting Time


After mixing the spawn, cover the bucket with plastic wrap. Make sure that the holes are not blocked. You can also put tiny holes in the plastic wrap. This will ensure proper exchanges of carbon dioxide and oxygen. Place the bucket in a warm and dark area of your house.

After several days, you should be able to see thread-like growth from the spawn. Depending on the general conditions, Reighi mushrooms will start growing in 15 to 20 days.

4. Fruiting


When you see the substrate covered in cobweb-like growths, it means it is fully colonized. That is the time you should move it to a room that is cool, well-lit and airy. Leave it for about two weeks then remove the plastic wrap. You should also start spraying water on the mushroom two to three times daily. Remember just to moisten, not to keep them wet. It will take several weeks before the Reishi mushrooms will grow to maturity.

5. Harvesting


When the mushrooms appear to have a fan-shaped, reddish and a wet lacquered appearance, that is the time when they are ready for harvest. You need to harvest Reishi mushrooms before they drop spores.

When harvesting, carefully twist and pull the mature Reishi mushroom. Be careful not to damage those that are still growing. Reishi mushrooms are normally at its highest production in the first two months. You may still be able to harvest one or two more times before your substrate will no longer produce.

Where to Get the Reishi Spawn

Reishi spawns are readily available for purchase online. There are three types of Reishi mushroom spawns that you can buy. The procedure of growing Reishi mushrooms depends on the spawn that you have.

Another type of Reishi mushroom spawn is the hardwood plugs. These mushrooms are dowels that are inoculated with mushroom spawns. They are normally hammered in hardwood holes or drilled in branches, logs or stumps.

There is also the in vitro culture. These spawns are pure mycelium which is prepared in Petri dishes. They are used by more advanced growers.
