Uncle Myc's Rabbit Manure Blend Mushroom Substrate

Give your mushrooms the nutrient-rich foundation they deserve with our premium Mushroom Substrate, made with 25% locally sourced rabbit manure from nearby small farms. Rabbit manure is naturally rich in nitrogen and essential minerals, providing a balanced, slow-release nutrient profile that encourages vigorous mycelium growth and generous harvests. We work directly with local, small-scale farmers to source fresh, chemical-free manure you can trust. Every batch is then hydrated to field capacity and fully sterilized at 15 PSI for 8 hours to eliminate contaminants and ensure a clean, reliable growing medium. This substrate is ideal for manure-loving mushroom species.
