Details:

These bags are provided with a series of parallel filter seams. Each seam consists of a double row of miniscule filter plugs, comparable to tiny wads of hydrophobic cotton wool. The level of gas exchange and the number of filters depends on the application: mother spawn, spawn, substrate, etc.

The Four Strip grow bag seams are unique because of depth filtration. As opposed to conventional spawn and substrate bags that use surface filtration. The filters guarantee a much more even and efficient gas exchange. While surface filtration relies on microperforation, The 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 5-6 lbs of spawn or substrate
