A Spawn Bags with Filter Patch is an autoclavable incubation bag with a micro-porous filter that allows gas exchange but prevents the passage of contaminants. Spawn Bags with Filter Patches are an economical substitute to canning jars. When producing bulk amounts of substrate, Spawn Bags with Filter Patches are able to hold larger amounts of rye grain, seed, or any substrate that you may be using. To create the needed air tight seal, please use an Impulse Sealer or a Mini Hand Held Impulse Sealer which highly reduces the introduction of contaminates. Like any commercial spawn bag, our bags are designed to be sealer prior to sterilization.
Measuring 21 x 8.25 x 4.75 inches, these bags are larger than most spawn bags, allowing them to hold more material. Widely used by mushroom growers throughout the world.
Don’t forget the sterilization tape!
It’s always good to know if your bags are sterilized.
Where are you going to case, fruit, mix or pour your substrate?

Quick tip. Spawn Bags with Filter Patches can not withstand a dry heat. Spawn bags with or without a filter should not be used in any form of a dry heat. For example, an over or flame based area. Grain based spawns need both heat and pressure to proper sterilize. The use of either a pressure cooker or a steam sterilizer (also called an autoclave) is needed to kill any contaminates or microbes residing on the grain. Most will cook/sterilize grain for 1.5 to 2 full hours once 15 P.S.I. has been reached. After that time has passed, you should let the fully cooked spawn sit for at least 8 hours before inoculating.
One last quick tip. If you cook in the evening, once the cook time has ended. You can just turn off the heat and walk away. Letting the spawn cool down over night.
