Grow with the exact substrate used by legendary YouTube mycologist Willy Myco. After years of demand from growers around the world, Midwest Grow Kits is proud to be the only official producer and vendor of Willy’s Blend in the continental USA—made with ingredients imported directly from Brown Treasure in Puerto Rico, Willy’s trusted partner and the origin of his famous manure mix.
This isn’t just another substrate.
This is the substrate the community knows, respects, and talks about—the same formula that has appeared across Willy’s tutorials, grows, and side-by-side results for years. Time-tested. Grower-approved. Proven in countless successful harvests.
To support Willy’s mission of getting his famous mix into the hands of more growers—without delays or high shipping costs—we formed this exclusive partnership with Willy Myco and his team. Shipping from Puerto Rico can be slow and expensive, so by producing and distributing Willy’s Blend from our centrally located Illinois facility, we’re able to offer faster delivery, lower shipping costs, and a more reliable supply.
With our fast fulfillment team, growers across the continental U.S. can finally experience Willy’s Blend the way it was meant to be: fresh, authentic, and delivered quickly.
