Hail, noble growers! I’m Ashley, the reigning Queen of Queen Substrates—here to help you cultivate like royalty and honored to share this journey with you.

Like many growers, I fell in love with mycology but kept running into the same issue—contaminated substrate. No matter how meticulous I was, I couldn’t find a consistent, high-quality growing medium I could truly trust. So, I took matters into my own hands. What began as late nights experimenting in the garage turned into years of research, refinement, and an unshakable determination to create the best substrates possible.

But Queen Substrates isn’t just about me—it’s about the passionate team behind the scenes. Together, we’ve built a company rooted in quality, integrity, and innovation. From sourcing premium, sustainable materials to implementing rigorous sterilization techniques, we take pride in every single batch we produce. Our goal is simple: to provide growers of all levels with a reliable foundation for success.

Based in Michigan, we’re more than just a supplier—we’re a community of cultivators, problem-solvers, and fungi enthusiasts who believe in doing things the right way. Whether you’re a hobbyist or managing large-scale production, we’re here to support you every step of the way.

Join us in redefining what’s possible in mushroom cultivation.

With Royal Regards,

Ashley

Founder, CEO, Queen
