100PCS Mushroom Planting Kit - 8"5"20" Thickened Growing Bags, 6 Mil Thick Durable, Tear Resistant, 0.2 Micron Porosity Resistant High Pressure Spawning Bags

I’ve never used any of the more expensive bags out there on the market, but these bags function perfectly. No contamination, bags vacuum seal in my pressure canner, no melted or exploded bags. I elevate the rack on the bottom of my 23 quart Presto With canning rings, pressure sterilize for 2 1/2 hours with 2 quarts of water, I do not surround the bags with any sort of protection against the walls of the counter, and I have zero issues. Will be buying these again and again.

Good thickness and size for 3-5 lb blocks.

The media could not be loaded. I love the thickness of the bag. They have a rigid quality to the plastic, making working with the gusset a breeze and keeping the upper bag upright, giving fruits plenty of air.Also, good price on 100.

They seamed at first to be strong bags but 2 out of 25 I’ve used out of a 100 pack have slit. One split out the side and one split out the bottom. The only luck part was it happened in my sterile tent.

Gets the job done!! Nice size spacious for many applications hold up in autoclave thick plasticWorth the money spent.

Good mushroom bags but rip very easy. Careful when bagging.

I like this product compared to others cause it can withstand the heat of steam sterilization over a long duration. Also heat sealing without sticking to the sealer itself. So 10/10

As described. Thickness is accurate. Filter held fine from pressure cooking. Price just as good if not better than ali or temu. Ordering more now.
