Good size, Good bags, good value
Item Package Quantity: 20
Held up well In The pressure cooker at 15 psi for 90 minutes. nice large size air exchange patches. I have had very little issue with my oyster mushroom grain spawn getting contaminated. If it does I’m sure it’s not the bag. I personally just use them once for grain spawn but they hold up well enough that I’m sure they could be at least 2x maybe more. Good product. Good price. Cheers! . ... show more

All bags RIPPED
Item Package Quantity: 20
Well I just lost over $150 worth of spawn and weeks of time with these bags. Pasteurized my substrate in these bags and added grain spawn the next day. Barely shook the first bag and the entire bottom ripped open. All of the other bags had rips in the bottom as well. No way in the world these would hold up in a pressure cooker if they can’t hold up to a quick pasteurization. Makes me question the other reviews here. I’ve been in mycology for years and wanted to try out a new brand since my usual go to were sold out. Never again!!! Ziploc bags hold up better than this mess. ... show more

Huge!
Item Package Quantity: 20
Easily big enough to sterilize 10 lb bags of substrate and string enough plastic to handle the PC at 15-17 (struggling with a propane burner) PSI for 2 hours without issue. Will absolutely purchase again

Cheaply made, will not seal
Item Package Quantity: 1
These are cheap Chinese made bags with the same price as Unicorn bags. I ordered some in a pinch while I waited on my Unicorn shipment and I should have just waited. Almost every bag would not seal and even when they did, they wanted to tear just below the seal. Even the ones that “sealed” wouldn’t hold up to the squeeze test, they would leak through the filter patch. Very low quality and not suitable for mushroom farming whatsoever. ... show more
