50 spawn / myco bags used for mushroom cultivation. These bags are made for durable 3 mil polypropylene and measure 4x3x18 inches. They have a special 0.5 micron filter which allows for the passage of air but not unwanted contaminates. They are autoclavable, reusable and can be sealed with an impulse sealer or just tied shut at the ends. Each bag can easily hold 2-3 pounds of substrate. These bags can be used for spawn production to inoculate bulk substrates like straw or compost, or you can fruit your substrate right inside the bag itself. The breathable technology behind these bags provide gas exchange, but exclude water vapor, so your spawn does not dehydrate. Mycobags are a far superior and economical choice when it comes to growing mushrooms as opposed to using the old outdated mason jar method.
