Reinforced Mushroom Grow Bags, 25 Count, Oyster Spawn and Grain Root Substrate Growing Kit with 0.2 Micron Filter, Large 8” x 5” x 20”, Thickest Available Heavy Duty 3 Mil Polypropylene Plastic

Excellent quality. Though, reading the packaging packet, Made in China, means it was sent to the U.S.A. and then sent to the U.K. Not really helping the planet! Happy with the product but not happy with my choice after finding that out on receipt of it.

Used 7. Had two fail almost immediately. They’re okay. Factor in your potential losses. You bet what you pay for i guess.

Amazing bag . Bought 3 packages 25 bags per package. Each was 30$ Now I see the price has been raised to 40$

There seems to be some confusion from a few of the reviewers that this is supposed to be a kit, and rated it poorly because they only received bags. The Title and description clearly state All in one grow bags, NOT a kit. If you actually read and pay attention to the listing and pictures, it's obvious that these are bags only. All in one is referring to the bags having a prepared filter port meaning they are ready to use without any additional alterations. Now with the confusion out of the way, on to the real review. The quality of the bags is much better than some of the other brands that I have tried. They are a little more expensive compared to some others at the $.998/ea cost that I paid, but I had zero failures in bag structure or performance and zero contamination. The 3 mil is very durable, seals easily and completely without leaking or tears when I use an impulse sealer. With this thickness they are easy to stand up and fill, I am never concerned or careful moving full bags around, or worrying about seams or punctures. I've even used a few of these bags more than once for grain spawn(something I had never even considered trying with other bags) just to see if I could, and they actually worked perfectly. The .2 micron filter patch has been perfect for contamination free fresh air exchange. Bottom line, if you are looking for a sturdy, well made reliable grow bag that can handle 5lbs (or more) of substrate this is an excellent choice. I will definitely be purchasing more in the future.

Buen tamaño pero son más frágiles de lo esperado, aún así funcionan

These are really nice bags, plastic is thick. Size is bigger than I expected but that just means more substrate and more mushrooms!
