The "Coolest" Substrate in the Game.
At Moscow Mushrooms, we don’t settle for generic compost. We use Alpaca Black Gold—a naturally "cool" manure sourced directly from our own herd. While many other manures are high in ammonia, our alpaca-based blend is rich in NPK without the risk of "burning" or stalling delicate mycelium. produced and refined locally, we know exactly what goes in, so you know exactly what you’re getting.
Give your mushrooms the foundation they deserve. Experience the Black Gold

Great harvests are built on a solid foundation. We’ve perfected The Moscow Jar—a proprietary, professional-grade blend of hydrated rye and white millet. • The Synergy: We pair the nutrient-dense power of rye with white millet’s thousands of micro-inoculation points to supercharge your colonization speed. • Arrival-Ready: Every jar is pressure-sterilized and ready for immediate use. We handle the mess and the prep; you focus on the growth.
