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.

What if my grain bag is contaminated?

Customer satisfaction is critical to us. We sell a high-quality product created to maximize yield at an affordable price. Other vendors and sellers may also provide a good service, but our sterile grains come with a guarantee. 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.

Made in the U.S.A and Cash the Border Collie LOVES them! No stomach upset!
Our dog, Cash the Border Collie is 55 labs and he LOVES these. We bought these a while ago and they were put away in an odd cupboard. Found them a couple days ago and I decided to see if Cash would eat them. He is not much of a rawhide dog. Well, I think we have found his brand of BEEFHIDE He is one happy camper with this treat! We bought these mainly because they made in the U.S.A. While they may not be the all natural ingredients some look for, it is a treat and he likes it. 20 pk Assorted Beef and Chicken 5" rolls (Chip rolls) 100% American Beefhide Follows GFSI food quality standards Ingredients: American Beefhide, Maltodextrin,Chicken flavor, beef flavor, Caramel, Hydrolized poultry Liver, Brewers dried yeast, Guar Gum, mixed Tocopherols. Ok, the yummiest part of the ingredients to me is the Caramel. I know, bad for Cash's teeth. But he will get these ONLY if he is a Good Dog. And if you look at the front of the package the dog is saying 'I've been good.' The beef flavored ones did leave a small stain that I cleaned up easily, but really, he ate it within 10 minutes so not much of anything. I think the people who are complaining about staining have dogs who are slower chewers. No staining with the chicken flavored rolls. Cash does not seem to care if he gets the beef or the chicken. At first he licks the roll for a minute or 2 and then he can't wait any longer and the chewing begins. He has not had any diarrhea or any other stomach problems with these. They are small, but we knew that when we bought them and we knew they wouldn't last long. That's ok, they are a treat, not a bone for him to chew on forever. Hope you like the pictures. Sorry about he red eye. If you find this review helpful, please click the button below.

Good for kittens & cats too!
Size: 15 Inch
Bought this for our new kitten, 5 months old, and didn't know if it was a good purchase or not. He loves it! He can chew on it, drag it around the house, interact with us too. And he hasn't lost or destroyed it. The only disappointment is the head squeaker stop working. The placard stated it would work even if bit. Not a big deal, though; kitten doesn't like the squeak. LOL

My dog's favorite toy, but
Size: 15 Inch
My dog loves his "lizzie" but the quality has gone down. The leather is thinner and easily torn, exposing the squeaker which becomes a swallowing hazard. Of course, no squeaker and half the fun is gone. For $10, I won't be buying any more of these. Sorry about that my furry friend.

Almost as good a chewing on my belt.
Size: 25 Inch
My corgi has always loved chasing her leash or a belt so I thought the snake would be a good fit for her. It quickly became her favorite. The squeakers lasted for maybe a month? Once there was a hole then we took them all out so she wouldn't choke. The snake without the squeakers is still a favorite. She's been chewing the tail end consistently and likes to lick it for some reason. I recommend this as a good tug toy. I like that it was made of leather.
