50Pcs Mushroom Growing Bag 6 Mil Thick Mushroom Spawn Bags Autoclavable Bags 8"x5"x20" Mushroom Grow Kit 0.2 Micron Filter Mycobag Grow Kit Tear Resistant Strong

I have tried many different mushroom bags and these bar far were the absolute best! Their thickness was obvious when compared to others. Realize that when vendors declare the MM thickness of the bags, SOME of them base that on the ENTIRE bag folded. In other words they are telling you what two sides are equal to in MM thickness rather than the thickness of just one side. This is misleading. These bags are nice and thick. Hold up in an autoclave.

Excellent results with these bags, holds up to autoclaving. I don’t have an impulse sealer but I can use my vacuum sealer and reinforce the seal with a strip of duct tape.

These are amazing and durable bags. They come the next day with prime so it’s super convenient!

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.

While most have held up after being autoclaved at 15psi for 3 hours, some of the bags have split where they wrinkled during cook, making sealing difficult. The plastic, after cook, feels brittle and weak, making me uncertain about thr structural integrity of a whole block being jostled around in any way.Bought for the price and need, have decided to go with another option instead going forth.They did the job, but not particularly well.

Good for the price but the centers do not seal well for some reason and I use a high quality sealer.

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.

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