Autoclavable Mushroom Bags

Autoclavable mushroom grow bags consist of a polypropylene bag with a filter patch. You’ll find them in a range of sizes with various filter patch types. Thanks to their high temperature resistance, you can fill these empty grow bags with your own blend of raw ingredients before autoclaving them to create DIY sterile grain or substrate.
