SUCOHANSMushroom Bags - Large Size 8" X 5" X 19", 0.5 Micron Filter 3 Mil Polypropylene, for Substrate Mushroom Cultivation

Good mil high quality bags

I use these to sterilize grain. I normally buy a more expensive version but I found that there’s no difference. At a certain thickness they all work equally. Probably made in the same factory.Also arrived really quickly which is always nice

This brand has several sizes the large are great, very good quality filter patches and easy to fold, and they seal great with impulse sealer. The xls are great also, very big bags I live them for fruiting. Now the smaller size bags I didn't care for they were very thin and hard to fold they didn't burst or anything and the filters were good just hard to work with

Using these as 5lb blocks with rehydrated wood pellets doped with oat bran. Out of the first 10 that I've used (2.5 loads in my pressure cooker), 2 of them burst out the seam. Not a deal breaker, as I've had 8 blocks go to fruiting, no contamination or other problems. Just load and unload a little more cautiously, and they're alright.

Had great sucess..nice price too

I pasteurized wood pellets in the bad no problem, after adding grain and sealing it I mixed the bag up. Now there are tiny little rip from the grains scratching the inside of the bag. Tried taping them all up but it's basically the entire bag.

No contam issues and a lot more efficient in space in the pressure canner than canning jars

There bags… they indeed work for the intended purpose
