About Us

This is a Passion Project 

Spencer's Shroomery began as a passion project between two brothers, Will and Spencer. Our first encounters with the fungi of the Sonoran Desert sparked a love for mushrooms, eventually leading to a full-blown fascination with fungi. Soon, we began experiments with cultivating gourmet mushrooms and fell in love with the process. Now, we want to help share the magic with Tucson.

Our Story

As beginners, we encountered many headaches that made it difficult to grow mushrooms. Inconsistent sources, high cost-to-entry, high shipping costs, and difficulty sourcing products made growing more of a pain than a pleasure.

This is where Spencer's Shroomery steps in.

We are working to build Arizona's first one-stop mushroom cultivation supply store!

Locally focused

In nature, fungi are stewards of their ecosystems. They partner with other soil microbes to help regulate soil health and form symbiotic relationships with plants, focusing on improving the overall forest community. Taking a lesson from fungi, we believe that it is important to support local ecosystems. We work closely with local small businesses and Arizona family farmers to bring you cultivation products you can depend on.

Environmental commitment

On the same note, we believe that we should all take a note out of the book of fungi and do what we can to care for our planet. We make an effort to minimize our environmental impact by...

  • Supporting Regenerative Agriculture

    We proudly source all of the organic grains used in our products from Oatman Flats Ranch, a family owned and NCOF certified organic farm pioneering regenerative farming practices in hot and dry climates.

  • Engaging in Bioremediation Projects

    Spencer is currently researching the potential of fungi to help save the Arizona rivers from invasive Tamarisk shrubs. Tamarisk is a highly damaging species that increases topsoil salinity, accelerating erosion and pushing out native species like Cottonwood, Creosote, and Mesquite.

  • Community Cleanups & Forays

    During mushrooming season, we host weekly forays to the Santa Catalina mountains to observe the local mushrooms and pick up trash along hiking trails and in campsites.
