- [Ultra-Thick 6 Mil Durability] Unlike standard 3 mil bags that tear easily, our mushroom grow bags are engineered with extra-thick 6 mil polypropylene. These heavy-duty spawn bags are tear-resistant and withstand high pressure, ensuring your substrate stays secure without bursting during preparation or sterilization.
- [Professional 0.2 Micron Filter Patch] Master the art of contamination-free cultivation. Each bag features a premium 0.2 micron filter patch that allows essential gas exchange (fresh air in, CO2 out) while effectively blocking contaminants and bacteria. Perfect for creating a sterile environment for mycelium colonization.
- [Autoclavable & High-Temp Resistant] Designed for serious mycology enthusiasts. These autoclavable bags remain pliable and strong even after sterilization. Safe for use in pressure cookers and autoclaves, they are the ideal vessel for sterilizing grain, straw, sawdust, and other mushroom substrates without melting or becoming brittle.
- [Spacious 8"x5"x20" Capacity] Maximize your yield with our gusseted design. The 5-inch side gussets allow the growing bags to expand and stand upright, holding 3-5 lbs of material comfortably. This clear design makes it easy to monitor mycelial growth and spot contamination early, essential for magic (high-yield) results.
- [Versatile Cultivation Tool] Whether you are growing Shiitake, Oysters, or Lion's Mane, these myco bags are the industry standard for both spawn production and fruiting. A must-have addition to your mushroom grow kit supplies for both home hobbyists and professional laboratory use. Note: Bags are sold empty; substrate/spawn not included.
