Reinforced Mushroom Grow Bags, 10 Count, Oyster Spawn and Grain Root Substrate Growing Kit with 0.2 Micron Filter, Heavy Duty 3 Mil Polypropylene Plastic

I bought a grow kit and was fascinated by the whole mushroom growing process. So I’ve decided to create my own substrate and use the spawn I bought online to try. It has been only two weeks so my experience is limited thus far. The bag is easy to use, relatively cheaper than others on Amazon. I was really surprised how much substrate the bag can hold. I used pasteurized straw and it took 8 lbs and one lb of grain spawn and still have plenty of room in the bag. Overall, it was a positive experience for a beginner using this bag.

Great bags I was able to heat seal these with a hair iron on low setting. They will work for pressure cooker sterilization but you need to make sure the bags don’t contact the walls or they will melt I used aluminum foil to protect. Will buy again

I gave 4 stars because the bags come folded and because they are thicker the longer they sit with the crease in it the more likely you will have a broken seal/ small hole and not know it until its leaking all over the place. 9 out of 10 bags were Fine. Other than that for the price these bags are phenomenal. They are sturdy, I can rewrap and readjust without the bag getting all crumpled and impeding the ability to see clearly through the bag. They withheld 2.5 hours of pressure cooking. I impulse sealed them after sterilization and ALL were good but that 1 bag.which is still a win in Mt opinion. I am in process of order the 25 pack now because I was surprisingly impressed. You usually get what you pay for with things like this. Price is right. They arrived quickly, and held up for all I needed them to do.100% recommend. Especially for mycology work and the use of heavier substrates you Ned to have durable heavy duty bags yet still be able to see whats going on inside of them. I have had thicker ones where you really can't see much. With mushrooms you need to be able to visibly see as much as you can at all times to spot contamination. Hope this helps!

I’m using these bags just to sterilize my substrate but not to grow in. I’m using a pressure cooker and am reusing the bags. This is my first time to purchase mushroom grow bags so I really can’t compare. They work fine for my purposes.

Grow mushrooms, friend.These make it righteousHave fun mycelium wo/man

Non sterilized, all my crop from all bags developed mold. Green mold, and after reaching out to seller, no response. I sterilized 6 myself, alcohol and peroxide, filter is not as advertised, not fully adhered to bags. Don't waste your money. Sturdy bags for ANYTHING else but growing mushrooms.

This is a thick durable bag. Very sturdy can pressure cook the bags.

From the bottom corner where it was sealed I had a bag slowly leak
