Square gusseted bags maximize the amount of material each bag can hold and can help increase the number of mushrooms. Our spawn bags are the ideal size for both the home and professional user and will fit into a wide range of pressure cookers/autoclaves.
The bags can be sealed using an heat sealer or bag clamps. We have two sizes of these bags available at the moment, they are same specification varying only in the dimensions of the bag. Injection port pore size: 0.2m. Filter patch pore size: 0.2m. Due to the size of filter do not pre-seal these prior to sterilisation.This item is made of polypropylene.
