Mushroom supplements & grow kits

What is Flatland Fungi?

Flatland Fungi started with a genuine fascination for mushrooms and more than a decade spent learning how to grow them. What began as a hands-on passion for mycology eventually grew into our own mushroom farm and a business dedicated to helping others experience the incredible world of fungi. After years of working with cultures, growing mushrooms, and supplying fellow growers, creating functional mushroom supplements felt like a natural next step. We’ve always believed that great mushroom products start with truly understanding mushrooms, and that’s the experience we bring to every supplement we make.
