This bags seams are unique because of depth filtration. As opposed to conventional spawn and substrate bags that use surface filtration, this filters guarantee a much more even and efficient gas exchange. While surface filtration relies on microperforation, this filters are composed of randomly arranged fibers in which microorganisms get trapped, much like the HEPA-filter system. This allows a fluent gas exchange without a drying-out zone below the filters, while still forming a firm barrier against microorganisms.
Ideal for 2 – 2 ½ lbs of spawn.
