TEXALAN(R Mushroom Grow Bags with 0.5 Micron Filter 3 Mil Polypropylene for Substrate Autoclavable Mushroom Cultivation 8"X5"X19", 10 PCS

The media could not be loaded.  These bags have filters that are coated with some type of plastic. It looks and feels like straight up plastic. I tried to blow through this piece to see if it's breathable and it's not. I was wondering why my grow kept stalling and contaminating even though I was using clean cultures. As soon as I switched to bags with other filters my grows took off quickly. It's a bit odd that Amazon is not allowing the other bags to ship to my area even though grow bags are 100% legal throughout the whole US. Seems like Amazon is sabotaging. Go to Mycology suppliers online stop buying from Amazon if they want to sabotage hit in the pockets.

Pure garbage, bags melted in the pressure cooker. Waist of time , grain and money.

These bags are the proper size for 5-7lb blocks. Thick plastic great quality steam autoclaved for 3 and a half hours. Exactly as described.

I love these bags, I always wait for these ones to come back in-stock as I will not buy anywhere else

These bags seem strong however may contain DEHP which was not advertised. Polyethylene should not contain DEHP. It is unclear if DEHP is in this product or manufactured in a facility where DEHP is used.

The thickness is so much better than other large bags I've used that store, or melted in my PC... I have 0 worries about that with these... would definitely buy these again
