Large Mushroom Grow Bag
[0.5 micron filter]


Our most popular myco bag. Large, autoclavable mushroom filter patch bags measuring 8" x 4.8" x 19" with gusseted sides and a 0.5 micron filter. Optional rubber self-healing injection ports available. These bags are ideal for clean sterile spawn production. In many cases, the bags can actually be used as a fruiting chamber. The high filter on these bags allow you to put more grain or substrate in the bags when compared to most other bags on the market. The microporous filter patch allows for filtered gaseous air exchange while keeping contaminants out. You will need to seal these bags with a heat sealer or a mushroom bag clamp.

These bags are not intended to be sealed before sterilization, however they can be successfully "pre-sealed" before sterilizing if all excess air is removed from the bag, excess bag material is neatly folded around the bag, and the bags are allowed to cool slowly and completely before removing them from the sterilizer.

These bags are amazing, they're perfect for both bulk amounts of spawn and even using them to colonize and fruit sawdust blocks. In my personal experience sealing them before sterilizing them causes the bags to swell up inside the pressure cooker so I recommend using scotch tape to securely tape down the bags regardless of weather or not your using some tyvek filter.

Not much to say here... these are the standard bags that everyone carries... they work great, simple as that. One thing i can say about these bags is that they are the cheapest spawn bags i have been able to find for sale online
