Review: Great bag that can withstand high heat! - worked as intended, did not melt or burn inside the pressure cooker for 3.5 hours. I highly recommend if you;re growing mushrooms, sterilizing anything. Plus there were 66 bags in the package! Which is a bonus. highly recommend to mycologists enthusiasts, it's a solid bag. Comes with the white filter only. If you need to inject anything in it you need to puncture the bag and then tape it. Or you can buy the self healing sticker. Highly recommend it!
Review: Work Great if Used Correctly - These mushroom bags work great but they will burst in the PC if proper precautions are not taken. First, they cannot come into contact with the bottom or sides of your pressure cooker (PC). The PC will get very hot and it will melt the plastic. I place metal canning rings under the canning rack and then drape cloth over the rim of the PC arranged so that the interior is completely lined with cloth. Then I load the bags and then fold the cloth over top of the bags to clear the rim of the PC once loaded. Second, you cannot have any air in your bags or they will pop. The air expands under pressure — a lot! — and the filter patch does not provide enough ventilation to allow excess air to escape. The bags will then pop, and you will probably hear it. There are a couple of ways to prevent this. One is to not seal the bags until after they are PCed. This does complicate sealing the bags because the PC will wrinkle and distort the plastic. It is also not foolproof because if the bags are rolled tightly closed as per common practice then they could burst anyway. The safest way to prevent air from bursting your bags is to just not have any. Push all the excess air out of the bag so they look like they are vacuum sealed (which btw is impossible with these bags because of the filter patch). . Once all the air is out of the bag you can seal them and PC or else PC first as per your preference. I personally like to seal the bags before pressure cooking because they seal better, and I can verify that the excess air is fully removed before they go into the PC. If the air is not removed then you will observe a noticeable pillow of air inside when you try to roll them up. I seal my bags as close to the top as possible so that if necessary I can open the seal, remove the excess air, and still have enough head room to reseal the bag. If you follow these precautions then you can avoid bursting your bags on the regular.

## Features

- AUTOCLAVABLE MUSHROOM GROWING BAGS - Made from polyethylene (PE) plastic, these bags are designed to withstand high temperatures that come with the substrate sterilization process.
- 6" X 5" X 20" CLEAR MUSHROOM SPAWN BAGS - These myco bags provide more than enough room for growing, spawning, and fruiting mushrooms. Even at this height, these side-gusseted bags can stand upright and hold the weight of their contents.
- DURABLE, STRONG, AND TEAR-RESISTANT MUSHROOM FRUITING BAGS - The bags are 80 micron (=3 Mil) thick (one side). This thickness, coupled with high-quality materials, make these mushroom grow bags stronger, more durable, and more tear-resistant than average grow bags of the same size and design. They can withstand heat and a considerable amount of swelling.
- EFFECTIVE AND EFFICIENT CONTAMINANT FILTERING WITH 0.2 MICRON FILTER PATCHES - Allow the efficient exchange and passage of gas without letting contaminants in. The very fine filter patches provide optimum filtering action without sacrificing breathability. And in the rare event of contamination, the clear bags will prove advantageous. It will be easy to spot contamination and monitor substrate moisture levels.
- GET MORE WITH OUR SUPER-VALUE PACK - For the same price, you can get 10 more packs! These 60-pack Autoclavable Mushroom Growing Bags will allow you to grow or spawn mushrooms like a true pro. Thicker, more durable, and most importantly, more affordable!

### ⭐⭐⭐⭐⭐ Integrity/Withstanding Heat/Metal Contact wasn't an issue
*by E***E on April 25, 2025*

I was afraid it would bust in the pressure cooker or melt in contact to metal like some of the other reviews were talking about but I had no issues whatsoever. Great quality, if I ever run out of the pack I'll probably be coming right back Also important side tip, watch some tutorials online for exactly how to position the bags because they can inflate and block pressure release if they arent positioned right. This wasnt an issue with the bags this was an issue with me putting them in willy nilly. Dont also forget to buy those self-healing injection ports yourself with the order as those do not come with this bag or most others I've seen for sale
