These autoclavable mushroom grow bags are our go-to for indoor mushroom cultivation and spawn production. Bags are made of 3 ml thick polypropylene plastic and are designed to withstand high temperatures. The 0.5 micron 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 (substrate/spawn):

• Fill half way, then fold the bag over twice.
• Make sure the filter is not obstructed.
• Be careful not to spill any substrate on the upper regions of the bag. If you do, wipe clean.

Recommended use (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.
