Midwest’s Wild Horse Bulk Substrate Manure Booster
Supercharge your bulk substrate with our most potent additive yet—Wild Horse Booster, a commercial-grade manure-based enhancer designed to increase mushroom size, improve flavor, and boost yield. Each 1 lb bag comes fully hydrated, vacuum sealed, and ready to mix with your bulk casing for incredible results using the monotub method or any bulk fruiting setup.
Why It Works
We’ve sourced wild horse equine manure from Northern Nebraska & Wyoming, known for its high nitrogen and organic content. Combined with a custom blend of vermiculite, pH stabilizers, spring water, and essential minerals, this booster hits the perfect field capacity every time.
To ensure maximum cleanliness and safety, each bag is processed using our liquid immersion pasteurization system—a 2.5-hour treatment that eliminates harmful bacteria while preserving beneficial microbes essential for healthy fruiting conditions.
