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

These work great. I fill them with 2.5 lbs of prepared oats, double seal them, sterilize for 45 minutes at 15 lbs, let pressure cooker coll overnight and no issues at all.

These bags are exactly what I needed to take my mushroom growing to the next level. I'm growing oyster mushrooms inside of a Martha tent. I had been using 1 gallon ziplock bags, and then using adhesive filter patches on them. These bags are bigger and come with a filter patch already installed on them. I they can withstand going in a pressure cooker so sterlization of growing medium can be done in the bag.

So far so good. Brought about 20 bags to fruit. Sometimes it's difficult to get them to seal. But I think that's my struggle. Not the bag.

Perfect bags. Exactly what I needed, perfect

Not as strong as others are making it sound. Going thru reputable mushroom supply place for all mycology needs from now on.

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.

Arrived as expected. Good for two, sometimes 3 uses.

I’ve been buying these for years and they’ve worked great until the bags changed on our last order. The new bags suck. Had about 50 bust in our autoclave and another 25 wont seal correctly.
