I recently got the opportunity to go to a mushroom farm called What The Fungus (WTF). It is in Summerland, British Columbia and is owned by Brian Callow. I learned some interesting things about What The Fungus, the owner, and growing mushrooms while I was there.
What the Fungus
What the Fungus is a business that grows mushrooms! It sells mushrooms at local farmers’ markets and restaurants. Impressively, WTF sells mushrooms to about 45 restaurants. A crazy fact is they grow 600lb+ per week!
An interesting thing is that What The Fungus (WTF) is a seasonal mushroom farm. That means that they don’t grow mushrooms indoors and in the winter.
A cool thing it that WTF mills its own lumber and is the main supplier of unicorn bags in Canada. They have also made an new greenhouse design. It has a win-win partnership with Bartlett, a tree pruning company, because WTF gets free wood chips for production blocks and Bartlett doesn’t have to deal with them.
What the Fungus partly relies on offering a weekly course for people that want to learn about growing mushrooms (for more information go to What The Fungus.)
A sad thing is that they don’t do tours.
Brian Callow
I found it surprising that Brian used to work in a restaurant. It’s really cool that he builds his own machines through trial and error. One of Brian’s 2020 goals is to grow and sell 1000lb+ of mushrooms a week. It’s awesome that he has been growing mushrooms for 9 years. Brian has had a crazy amount of setbacks which makes him very persistent.
Growing Mushrooms
WTF grows mushrooms on a commercial scale by having test tubes with mushroom cultures which they transfer into petri dishes. Then they transfer the petri dish culture into grain spawn or sawdust spawn. Finally, they transfer the spawn into production blocks. The production blocks go into the labs to colonize. After that they bring the blocks into the grow tents outside to fruit.
Growing mushrooms in a desert is interesting because not a lot of people do it. The cool thing about growing mushrooms in the desert climate is that there are less bugs. He also has a few frogs to help him out too.?
Because it is so hot. WTF has grow tents covered in shade cloth that has shelves to grow mushrooms. Some other things that are helpful are that the grow tents have specialized humidifans which make a perfect environment.
To get an early start in the spring What the Fungus freezes cold tolerant species like Blue, Pearl, and Tree oyster mushrooms and the mushrooms fruit in the spring.
Some of my own mushroom growing goals:
I few goals that I would like to work on. Some of them include:
- To one day work at What the Fungus.
- To learn how to make my own production blocks.
- To be able to take What the Fungus one week course to learn more about growing mushrooms.
- To successfully grow a King oyster mushroom and a Tree oyster mushroom from two ready to grow kits.
