Building on over 20 years of experience in the mass production of pre-filled and pre-sterilized substrate bags and has hands-on working knowledge of the use of autoclaveable filter patch spawn bags for bulk spawn production. Our products are made using the strictest of quality control measures and our pre-sterilized substrates are guaranteed to arrive contaminant free (or replacement will be issued).
Original quality Legacy mycobag products began a new era in home mushroom cultivation.
Our empty spawn bags, manufactured to our specifications, are made with high quality polypropylene plastic and can be autoclaved to 265 degrees F. A breathable filter membrane on each bag provides for different gas exchange rate with different membranes. Membranes are designed to provide gas exchange rates for different applications; micron size range from 0.1 to 5 microns and each membrane has a nominal gas exchange rate.
