15 Pack Mushroom Grow Bags with 0.2 Micron Filter Patch, 8 x 5 x 20 Inch

These are great. Quality made and solid.thickness is standard- these are easy to use/seal. (If you don't have a heat sealer, just tape shut with micropore tape. If you don't have that, then just some clear box tape (like moving box tape)They are great at keeping moisture in without being too wet, and the filter patch is perfect. You can slowly push air out of it once your substrate is inoculated.

While the thickness doesn't feel like 6mil, these bags are solid. I ran one through my insta pot for 90min and it worked flawlessly. If your bags are exploding, you need to heat seal them better. The bags are quite big and definitely a good value at $0.50/bag. Will buy again for sure.

These bags are great. If you’re into mycology, these bags are for you. They have high performance capabilities that allow them to not melt while being pressure cooked. These bags never rip or tear. They are clean and deliver on time! Thank you!!!

Good product. Thick bags. The ones that I have used so far did get brittle or leak after putting them under pressure. They are easy to crease at the gussets.

So, I’ve ran these through the pressure cooker with grain and with CVG held up very well. I’ll be able to use these multiple times not just once. Very happy no bursting and seal well. Great price great product.I’ve bought other bags here and they were trash so happy I’ve found a bag plug

Product works well for me to grow mushrooms at home and make it a lot easier to control humidity without expensive equipment or the space requirements needed. Bags are sturdy and allow you to see the growth of the mushrooms. The size works to allow for easy storage and look great.

Ive bought bags from this vendor for the past year and they've been great. But this last batch of bags are now much more brittle and have been leaking slightly after a presto run. sadge

These worked 1000x better than drilling holes in buckets. We've had very good luck with the mushrooms we've grown in these using hardwood pellets as medium.

Despite what some reviews say, these bags didn't melt in my pressure cooker. I made sure they were lifted off the bottom and that my cooker didn't run dry and they worked a treat. Totally able to use them for fruiting blocks.

These were a good size and the filters seem ok but a couple of them seemed to lose their shape after pressure cooking? Not sure if it was something I did wrong or the bags not coping well with the pressure?

Aguantan autoclave sin problemas. Buen tamaño (no son pequeñas)

Very good bags.
