## Description

Tips on Using These Mushroom Growing BagsThese bags are sterile but they can be contaminated during handling. Wear nitrile gloves and a face mask when handling the bags. Also, disinfect the work area where you need to prepare the grow bags. If you are using a pressure cooker (PC) to sterilize your substrate, ensure that the bags don't have direct contact to the surface of the pressure cooker. Direct contact with a heated surface, under pressure can cause the bags to deform or burst. It is advisable to not pre-seal the mushroom grow bags during the sterilization process. This will only increase the chances of the bag bursting especially if you are using a pressure cooker. You'll need to seal the bags immediately right after sterilization, though. This is to prevent outside air from contaminating the growing medium. Impulse sealers will provide a better and a more consistent seal. Do not melt or cut holes on the mushroom grow bags to spawn the substrate inside. All you need to do is tape a small part of the side of the bag opposite the filter patch and inject the spawn or liquid culture through the tape and directly to the substrate. To seal the injection hole, all you need to do is to tape the hole over. You can also reuse the hole for injecting water in the event of the substrate drying out. Just ensure that the hole is resealed properly with tape.

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.
Review: Good quality bags, worked well for pressure cooker use - Used these bags for substrate sterilization in a pressure cooker and overall they performed well. No issues with bursting during the process—as long as you let the pressure cooker cool down properly before opening. If opened too soon, they can burst, so cooling time is important. The bags are clear and good quality, and they held up fine after sterilization. No noticeable deformation or issues once cooled. Sealing was a bit tricky, but that may be more related to the sealer than the bags themselves. After continuous use, the sealer got hotter and started slightly melting the plastic, so we had to let it cool down between seals. These are 3 mil bags with an 80 micron filter, and they seem to do the job well for general use. They do not come with inoculation ports. Included a photo showing early colonization using these bags. For the price ($39.99 CAD for 60), they offer good value overall.
