What is a sterilized grain bag used for?

These sterilized grains can be used to make a grain spawn bag to grow any kind of mushroom. The point of sterilizing grains is to kill all living organisms and provide a clean source of nutrition for mushroom mycelium. Grain spawn bags made from our sterilized grain are guaranteed to give successful results.

Ready-made sterilized grain bags are a convenient and reliable way to get started with mushroom cultivation. They can be used to grow mushrooms indoors or outdoors, and they make the process of preparing grain spawn much easier. Every sterilized grain bag comes with a self-healing injection port to eliminate the need for a laboratory or cleanroom.

Instructions

Each bag comes with its own instructions, but in general, you will need to:

Thoroughly clean and disinfect the work area

Inoculate the grain bag with mushroom mycelium through the injection port.

Provide the bags with proper growing temps (room temp is fine) out of direct sunlight until they are fully colonized and ready to use.

FAQ

Why should I use pre-sterilized grains instead of preparing my own?

Sterilizing is an essential step in the process of growing mushrooms. We ensure that every bag is adequately sterilized to provide the best possible growing conditions for your mushrooms. All bags are incubated and inspected before shipping to ensure no contamination.

By purchasing pre-sterilized bags, you save time that would otherwise be spent on preparing grains and performing the sterilization process. Whether you are a home grower or own a business, our sterilized grain can help you! Contact us if you would like to purchase bags without injection ports.

What is included in a purchase of a bag?

Each bag weighs 5 pounds and contains a proprietary mix of various seed grains, including but not limited to wheat, rye, milo (sorghum), and millet. Every bag comes with a 0.2-micron filter patch for gas exchange and an injection port for inoculation. Injection ports eliminate the need for a cleanroom or flow hood.

How are these grain bags made?

The bags are made by filling the bag with hydrated grain. The bag is then heated in an autoclave which kills any bacteria or fungi. Finally, the bags are heat-sealed in a cleanroom.

What is an autoclave?

An autoclave is a machine that uses pressurized steam to sterilize objects.

Why are pre-sterilized grains important for mushroom growers?

Our bags provide a sterile environment for the mushroom mycelium to grow. With no need to prepare grains, these bags make the process of growing mushrooms much easier and more convenient. Purchasing pre-sterilized grains saves time spent on sterilizing grains yourself. Our sterilized grain is guaranteed to give successful results, making it an excellent choice for any mushroom grower.

How long are grain bags good for?

The bags are suitable for up to 2 years if stored in a cool, dry place.

What is grain spawn?

Spawn is a mixture of grain and mycelium used to inoculate other substrates such as logs or compost. Spawn can also be used to start your own mushroom culture.

What types of mushrooms can I grow with sterilized grains?

The type of mushrooms you can grow will depend on the kind of mushroom mycelium or spores you have. You can find a wide variety of mushroom cultures on our website. If you are unsure what to purchase, our team is happy to help!

Do I need a clean room or flow hood to use these bags?

You do not need a cleanroom or flow hood to use these bags. The injection port allows you to inoculate the bag without being in a sterile environment.

Every bag is incubated for two weeks minimum and inspected before leaving our laboratory facility to ensure sterility. If grains arrive contaminated, we will replace them free of charge. Just contact us, and we will get a new bag right out to you.

Much higher quality then I ever expected at a great price
Size: 26"+17"+14"B(U/J Hook)
Perfect fit on my 2023 Mazda 3, they look and install exactly like the original OEM wipers but Mazda 3 can be a little tricky to install but if you search on the internet you will find plenty of helpful videos. They work really well without streaking or noise.

Excellent front wipers, rear slightly shorter than expected
Size: 22"+21"+11"(U/J Hook), Size: 22"+21"+11"(U/J Hook)
I purchased the 22", 21", and 11" windshield wiper blade set for my 2017 Jeep Grand Cherokee. The front windshield wipers (22" and 21") work perfectly—smooth, quiet, and they clean the glass very well with no streaks. Regarding the rear wiper (11"), it does work properly and gets the job done. However, it is slightly shorter than the one I previously had installed. To be fair, I did not measure my old rear wiper, but it appears the one on my vehicle was a 12" blade, even though this listing specifies 11". Overall, I’m satisfied with the performance, especially for the front wipers. Just keep in mind that the rear blade may be shorter than what you currently have installed, depending on your setup.

Nice wipers
Size: 26"+16"+12"D(U/J Hook)
I got the right ones. Checked and checked again. For my husband's subaru crosstrek. The front ones fit perfect. Installed super easy. Work nicely. Had alot of rain to check them out recently. Now the back one. Does not fit. Not sure what is wrong with it, but 2 out of 3 is good.

Finally, no more streaking and squeaking.
Size: 26"+16"(Top Lock)
Bought these a few months ago for my boyfriend’s car. It was for the purpose of replacing the OEM model that initially came with the car, as the squeaking was driving me nuts. Matching the pair to his car’s make and model here on Amazon was easy. The installation was easy as well, as they simply lock in with no difficulty for me. And they look fine as well. They’ve held up the last few months in the bitter winter here in the northeastern seaboard with no issues. No squeaking, streaking, or scraping. The material seems sturdy and of good stability, not flimsy. Definitely directing him to buy this brand again when they eventually need changed out.
