For your consideration are these top of the line mushroom grow bags. These large bags are 24" X 9.5" X 5" with gusseted sides! Large 0.2 micron filter grow bags with a high filter allow you to use much more substrate than most other bags available on the market. Use these bags for bulk grows and get great results. The 0.2 micron filter patch allows for proper gas exchange but excludes water vapor so your spawn does not dehydrate. The filter also keeps contaminants out. The material is polypropylene and is heat resistant up to 260F. Gas transmission is 1 in h2O.
0.2 micron filter 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, clothes pins or a similar device.
The uses for these bags include mushroom cultivation, mushroom spawn production, incubation of fungal products and bio-control industries.
