Willy’s Blend – Official Manure-Based Substrate

Our #1 Manure-Based Substrate

by Brown Treasure

Willy’s Blend is the original substrate formula personally entrusted to Brown Treasure by Willy Myco and taught to us in person.
This is not a recreation or imitation — it is the authentic Willy’s Blend, produced by the original company trusted to carry it forward.

Crafted in small batches and handled entirely by the owner, Willy’s Blend is built for growers who want consistency, reliability, and real support behind every bag.

What Makes This Version Special

Because you’re buying directly from Brown Treasure, your Willy’s Blend includes:

• The original, authorized Willy Myco formula — personally taught to us and produced by Willy Myco (a widely respected mushroom cultivator and on online educator in the community)
• Exclusive diluted-coffee hydration (Brown Treasure only), providing a small nitrogen boost for more vigorous mycelial performance
• Widely trusted for exotic strains, especially by experienced growers working with advanced and specialty genetics
• Eight premium, locally sourced ingredients blended at precise ratios
• Owner-produced and owner-checked — not mass produced by employees
• Premium organic inputs from Puerto Rico
  Our manure component is sourced from free-roaming horses raised on open pasture and natural forage in Puerto Rico—rather than from industrial or high-density agricultural operations. This provides a clean, naturally derived organic input from animals raised in low-stress, outdoor environments.
