0.2 Micron Filter Patch Mushroom Grow Bags










Dimensions | 8" W x 19" H x 5" D |
Thickness | 2.2 ml; polypropylene |
Filter | 0.2 micron |
These autoclavable mushroom grow bags are our go-to for indoor mushroom cultivation and spawn production. Bags are made of 2.2 ml thick polypropylene plastic and are designed to withstand high temperatures. The 0.2 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.
⚠ 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.

0.2 micron filter mushroom grow bags
This is the second batch of 100 that I’ve ordered. Out of the 170 or so that I’ve used so far, I’ve only had problems with one bag. I had inoculated it and was shaking it to disperse the spawn, and the filter split.

Awesome grow bags
I have only used a hand full of them so far. The filter patches seem to hold up very well during the PC process. I have not had any break loose from the bag or tear so for!!

Pleased with the product
Great Bags at a reasonable price! Super durable and holding up great.
North Spore
Thanks for your support!

Sturdy as expected
Bags are very durable. I’ve put them through the wringer, mixing substrate and water inside them, pc’ing them, and microwaving them. No burst seams, broken patches, or other failures. I’m sure they can be washed and reused, but at the price they are here, I’ll pay for the esas of use and can depend on North Spore for a contam free shipment.

Good cost and quality
Been using these for a while, just picked up from North Spore for the first time since they beat my other supplier on price by over 15%. Same great bags at a better value.

Great quality and value
So far these bags have held up great and I have had zero issues with contamination or breakage. Another great product from North Spore I will definitely be purchasing again.
Bagged
I recently ordered an recieved the autoclavable bags and was very impressed with them in every way, the packaging was spot on , the quality of the bags themselves was excellent as in construction & plastic quality. I've already used some and had 100% positive experience with them.They definitely hold up before, during and after being put into autoclave. Highly recommended, will definitely order more.
Love this Company!
Always so satisfied with the products I purchase for my team on NorthSpore.
Nice Bags
Great for doing a lot of substrate without having to worry about making bags.
Perfect Spawn bags
These bags are perfect size, I found them to be very versatile with different substrates. They are easily heat sealed too. I will be ordering more of these !
