For your consideration are these top of the line mushroom grow bags. These large bags are 19" X 9.5" X 5" with gusseted sides! Large grow bags with a high filter patch allows you to use more substrate then most other bags available on the market. Use these bags for bulk grows and get great results. The 5 micron filter patch allows for proper gas exchange but exclude water vapor so your substrate does not dehydrate. The filter also keeps contaminates out. We choose this filter size for its efficiency and it allows the bag to be sealed before you sterilize. The material is Polypropylene and is heat resistant up to 260 degrees Fahrenheit. Gas transmission is 1 in h2O. Out-Grow's large mushroom grow bags are acceptable for spawn running and bulk substrates. You will need a 12" or larger impulse sealer to properly seal these bags however you can get away with using paperclips or tape if needed. The uses for these bags include mushroom cultivation, mushroom spawn production, incubation of fungal products and bio-control industries.
