Website: smscollection.net | Email: wildhorizonsproject@gmail.com | Location: Marysville, WA
What We Do
WildHorizon LLC provides two complementary services for Washington State agricultural businesses:
- SMS Pickup Service: Recurring collection of spent mushroom substrate (SMS) — the used growing medium left over after mushroom harvests — from mushroom farms and growing operations. We handle hauling and responsible diversion so growers don't have to.
- Natural Compost Products: We process collected substrate into high-quality natural compost and soil amendments, available for purchase by farms, nurseries, landscapers, and home gardeners.
SMS Pickup Plans & Pricing
Plans are subscription-based with recurring scheduled pickups. All prices are per pickup visit:
- Small Plan – $75/pickup: Ideal for small growing operations. Covers approximately up to 1.5 cubic yards of SMS per visit. Accepted in bulk bags, totes, or loose.
- Medium Plan – $150/pickup: For medium-scale farms producing moderate volumes of SMS. Approximately 1.5–3.5 cubic yards per visit.
- Large Plan – $250/pickup: For high-volume operations. Approximately 3.5–6 cubic yards per visit. Custom scheduling available.
Pickup frequency options: weekly, bi-weekly, or monthly. A 15% autopay discount is available. Overage surcharges apply for volumes significantly exceeding plan limits. Contamination surcharge: $75 if loads contain non-compostable materials (e.g., plastic bags not removed).
Plastic-free discount: Customers who remove plastic bags from their SMS before pickup receive a 5% per-pickup discount.
