SUCOHANS Mushroom Grow Bags XLS Extra Large Size 10'' x 5.5'' x 24'' /Sealable Spawn/Myco Bags with 0.5 Micron Filter Designed for Mushroom Cultivation Growing (10)

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

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! .

If you can't afford or don't need the bulk from unicorn bags, this is a good purchase! I cannot tell the difference, I don't know what people are complaining about. 10/10 would buy again but I just got these while waiting on my bulk order to come through from unicorn.

I super glued a quarter to the jiggler of my presto PC for a little extra umph and these bags held up for 2 hours

These bags are huge. The biggest I could find. Good quality, and I didn't have to buy 50. I don't know if I will need that many, so 10 bags is awesome. .05 micron filter means you can grow mushrooms without opening the bag.
