Mushroom Grow Bags with Self Healing Injection Port - 15 Bags - Evviva Sciences - 0.2 Micron Patch - Thick 3mm Polypropylene - Autoclavable, Durable, & Tear Resistant

I usually make my own injection bags but when I get in a pinch I order through Amazon. These bags were exactly what I wanted.

These mushroom grow bags are perfect for at-home cultivation. The self-healing injection port makes inoculating the bags easy and keeps everything clean and protected. I appreciate the 0.2-micron patch, which allows the mycelium to breathe and grow steadily.The thick polypropylene is strong enough to handle autoclaving without any issues, and the bags stay durable throughout the process. They’re spacious enough for 3 to 5 lbs of substrate, making them ideal for larger grows. Highly recommend for anyone looking to grow mushrooms themselves.

My latest hobby has me venturing into the wonderful world of Mycology, or growing mushrooms. I had been ordering spawn bags online and it can get pricey after awhile. So I figured why not just make my own. So here I am. I ordered these bags without really thinking ahead, meaning that I might need an autoclave for sterilization. I do have a still box that I could use to fill the bags with substrate and seal the bag but contamination is so easy if you are not careful and an autoclave will sterilize everything pretty thoroughly.The bags themselves are nice and thick at 3.0 MIL and have a nice durable feel to them. Self healing injection port which I still slap a filter over after inoculation. The filter on the bag is at 0.2 microns which is pretty small so no contaminates should be able to penetrate but it will allow airflow in and out. I got 15 bags so just after making a few of your own spawn bags you're already saving a bunch of money. The makers also provide an easy to follow instruction guide just in case like me, this is your first rodeo. Autoclave is next on my list. All in all I am very stoked with these bags and I think you will be as well.

These are nice bags, long and thick. However, for the money, I have grown mushrooms in recycled bread bags. The advantage to these is the thickness, which is more protective, and complete see through so monitoring the growing media is enabled more. For my uses, I will share these, but my zip lock bags work well too, they are not as large and so again these add something to the growth process. It is just that they are not anything so special as to put that much money out for pretty ordinary plastic bags. The best advantage I can see is that the thickness might allow more than one grow period and can be reused after washing. I have not tried that yet, so don't know how they would hold up after washing.

I don’t usually review products unless I really love them. But this is wack. A few of the bags were kinda crinkled with tiny holes in the creases. There were human hairs in between the bags themselves and I was shorted 4 bags…. No good.

Good bags for mushroom growing. I like that they are transparent so I can see the spores through the bag. Made from a nice thick poly material. Rip resistant. Good size. Function well.

The bags just arrived and I haven't used them in the PC yet. That being said the plastic feels very thick and durable especially compared to another brand I bought on Amazon which ripped very easily. The filter seems attached well. The injection port is where I'm unsure of, it's held by an adhesive backing with a thin chamber of plastic cover the port area, for some reason I figured it would be a butyl self healing disc built into the bag.

I have not got a chance to grow in these yet. They do appear to be of good consistent quality. The edges and opening are what you would expect. I would definitely order again.
