MicacleFarms spawn bags are used for mushroom cultivation. These bags are made of durable 3 mil polypropylene. They measure 4 x 3 x 18 inches, have a self-healing injection port for easy inoculation, and a 1.5 x 1.5 inch 0.2-micron filter which allows for the passage of air but not unwanted contaminates. They can be used in a pressure cooker, steam sterilizer, or autoclave.
Our spawn bags can be used for spawn production to inoculate bulk substrates like straw or compost. The breathable technology behind the mycobag provides gas exchange but excludes water vapor, so your spawn does not dehydrate and you can fruit your substrate right inside the bag itself.
These side-gusseted bags give a sturdy stand-up bag after filling and a strong bottom seal. They are reusable and can be sealed with an impulse sealer, taped, or tied shut at the ends. Each bag can easily hold 2-3 pounds of substrate. Miracle Farms grow bags are a superior and economical choice when it comes to growing mushrooms. Other sizes, filters, and quantities are also available.
