TonGass60-Pack Autoclavable Mushroom Growing Bag Bulk with Microporous Filter Patchs - Large 8"x5"x20" Extra Thick 80 Micron (=3 Mil)| Mushroom Cultivation Spawn Supply Myco Bag Bulk Substrate Bags

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!

The media could not be loaded. This is my second order of these bags in year 2024 and the only complaint I might have is a few of them have not been pressed correctly at the bottom making it a little more challenging to get the sides lined up after filling with grain or substrate.I started my shrooming journey in 2023. Over time I perfected my liquid culture, grain spawn and substrate process. Over that time, I used up and threw away a lot of these bags, not because they were bad, but my process was not good.My process now is to bail my oat grain for 30 minutes, let it cool and dry enough to pass the tissue test. Then I bag up about 2 cups of that grain into each bag, line up the sides, roll the top down tightly until I get to the air patch, rubber band my little bundle and stick it in the Insta-pot. I let my bags run through the insta pot process on high for 1.5 hours, let the pressure fall and then carefully bring the bags out, pop off the rubber bands, unroll my bag of grain, put a heavy duty clip at the top where I folded up before the PC process and periodically shake my bags until all the moisture has absorbed back into the grain.I use two processes to make my bags of spawn. I use LC or grain to grain. If I use the LC, after I shoot the bag with 4-5 cc (my preference), I slap a piece of micro tape over the hole the needle made and then hang the bag by the large office clip at the top. If it's just grain to grain, I carefully unroll the top, toss so already inoculated grain spawn in, roll the top back down to the filter, put my clip on and hang the bag on a hook until it's ready.I then use that same bag for adding my substrate since I use a combo of pellets 1.12#, cotton seed husks 8 oz and 1/3 c wheat bran with just a little less than 1TBSP of lime for pasteurizing.From start to finish, this process of having a block ready to fruit takes about a month, 2 weeks for the spawn and then about 2 weeks for it to run through my substrate mix.Through all this process as described, I've never had a bag fail me. They don't melt in the Insta pot, they don't burst, they don't crinkle so horribly that they look like a mangled mess of plastic, and as I said at the beginning, this is my second time to order this brand. Unless they change materials or their process, these will continue to be my go to bags and I highly recommend them, especially for the cost per bag.

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 backAlso 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

I am new to growing mushrooms and this is my first time using bags that were not in a kit grow. They are very thick and seem to be well made. I have only a family pressure cooker so I was only able to sterilize 1 bag at a time . As long as you have plenty of water in your pressure cooker you should not have a problem with the bags melting or tearing. I used my vacuum sealer manual seal to seal the bags.I would purchase these bags again.

I am not sure If I got a bad batch but these bags have been terrible. After being sterilized the plastic because hard and sort of brittle. Also because of the change in plastic no matter the setting my impulse sealer will not get a good seal. Wasted much substrate and spawn on these bags :(

I bought these about a year ago and started off without any problems. I don't know it they deteriorate with age or what, but the last few batches came out of the pressure cooker with one out of four bags having a hole in it. I'll be trying another brand.Other than that, they seal with a food saver and have worked well.

So far so good. Strong bag.
