Our mushroom substrates undergo a meticulous sterilization process to ensure the highest quality and purity. The process begins by carefully selecting premium organic materials, such as sawdust, straw, or compost. These materials are then mixed with water and thoroughly hydrated. Next, the substrate mixture is carefully packed into sterilization bags or containers, ensuring proper ventilation. The bags are then subjected to heat and pressure in an industrial autoclave, effectively sterilizing the substrate. A five micron filter patch is an essential feature in mushroom cultivation for facilitating proper gas exchange within the growing environment. The filter patch has been engineered to facilitate the circulation of gases, such as oxygen and carbon dioxide, which are vital for the growth and development of living organisms. This feature helps to ensure that the environment inside remains conducive for the purpose it serves. Additionally, the filter patch also acts as a barrier, keeping unwanted particles and substances from entering the space.
