Green Box Mushrooms

Meet the Farmers

Green Box Mushroom operates a 30,000 square foot indoor mushroom growing facility in Gainesville, Georgia. After 25+ year careers in the IT field, owners John and Elizabeth Moon decided to apply their skills to sustainable mushroom cultivation. Today, they grow hundreds of pounds of natural oyster mushrooms each day and plan to expand to other varieties such as Lion’s Mane and Cordyceps soon. 

Green Box Mushrooms has a sister growing facility in Korea that has been growing mushrooms since 2001. By learning from Korea’s more developed mushroom market, Green Box Mushrooms is ahead of the game when it comes to the knowledge and technology needed to grow the  U.S. mushroom market. 

Green Box Mushroom is the only indoor bottle cultivation mushroom farm in the Southeastern United States. They are MGAP (Mushroom Good Agricultural Practices) certified by the USDA and produce fresh, natural oyster mushrooms year-round. Rather than importing mushrooms from overseas or relying on one of the few places in the U.S. that currently grows mushrooms, Green Box Mushrooms has a vision to bring specialty, fresh oyster mushroom varieties to consumers throughout the Southeast, and eventually across the United States. 

Regenerative & Sustainable Practices

Green Box Mushrooms take pride in being a sustainable and eco-friendly farm. Their sustainable cultivation practices include:

• Growing mushrooms in reusable bottles cuts down on waste and requires less water
• Use of agri-waste, such as peanut hulls, are used as a natural medium to grow mushrooms. Once the mushrooms are harvested, this medium can then be repurposed as a natural compost/fertilizer.
• Spent mushroom substrates are used to condition soil (four bulk bags can cover an acre of farmland). The substrate is filled with nitrogen and potassium, and the mycelium in the compost acts as a natural immune booster for the soil. Some studies have even shown that farmers that use mushroom compost have seen a reduced population of weed growth on their farm.
• Shipping container growing facilities will facilitate more local production meaning shorter transportation miles from mushroom to plate.
