About Our Substrates
Quality of Materials
At Mushroom Substrate, we pride ourselves on the quality of our materials, all of which are sustainably sourced. Our grain-based substrates, including rye berries, popcorn, white milo, red milo, oats, and our multi-grain blend, are sourced from local Amish Mennonite farms. These farms use natural farming methods, such as fish-based fertilizers and non-chemical weed control, to ensure the purity and sustainability of our grains.
Our substrates are available in various sizes and forms, including sterilized grain bags with self-healing injection ports, pasteurized manure-based mixes, wood-based substrates, and pasteurized straw. Every product is fully prepared and ready to use upon arrival, ensuring a smooth and effective growing process.
Preparation Process
The preparation of our substrates is where our experience truly shines. All grains are soaked, simmered, surface-dried, and then sterilized in mushroom grow bags at 17 PSI for three hours. This meticulous process ensures that the substrates are fully hydrated and free of contaminants, setting the stage for successful cultivation.
For our non-grain substrates, each mix is carefully prepared by hand, ensuring consistency and quality in every batch. Our large-scale facility, equipped with over 1,000,000 BTUs, allows us to maintain the highest standards of preparation using steam-jacketed kettles that provide even cooking and reduce the risk of burst grains. Our recipes have been refined over 15 years of experience, ensuring they are perfectly tuned for optimal mushroom growth.
