These autoclavable mushroom grow bags are ideal for indoor mushroom cultivation and spawn production. Bags are made of thick polypropylene plastic and are designed to withstand high temperatures. The filter also allows for ample gas exchange.

These bags are durable and clear enough to make monitoring growth easy and can be sealed with an impulse sealer, or just be tied to the seal.

Recommended Use For .5 XL Filter Bags(log incubation):

When growing chicken of the woods and hen of the woods on logs, we strongly recommend sterilizing 8" by 8" segments of oak log in a pressure cooker or steam sterilizer before inoculation.

• Incubate your sterilized log segments for a few months in XL sealed filter patch bags until they are completely colonized.
• After colonization period, logs should be removed from bags and partially buried under 2 inches of top soil.
• The mushrooms will fruit from logs and emerge out of the soil.

WARNING: POLYPROPYLENE MELTS ABOVE 25PSI AND 350°F

Plastic grow bags are designed to withstand high temperatures during sterilization. However prolonged direct contact with the base of an autoclave or pressure cooker can result in damage to bags.

• Never leave bags unattended in an autoclave or pressure cooker.
• Keep bags away from the metal sides of your equipment to avoid damage.
• Any sudden change in pressure will cause bags to rupture or burst.
• Always allow autoclave or pressure cooker to cool down and depressurize before opening to remove bags.
