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.

Our grain bags are kept in stock. This product usually ships immediately. You won't need to wait! Feel free to contact us to ensure we have the quantity you need in stock. If not, each order usually ships within a week. Discreet packaging is available upon special request.

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.

Winner of the aggressive chew competition
Color: No Stuffing Blue Eel
I bought several toys for an insane Jack Russell and this is the unlikely winner. It is a softer toy, but it is stitched together nicely and there are various components that distract the dog and keep him busy. First, it can be rolled up and stuck with small but strong Velcro patches, so it’s not just a sitting duck, the dog has to figure out how to unroll it which is fun. Next there are five little pockets on one side that you can put treats inside, which draw attention to the toy and give him another task. He did partially rip some of the flaps on the pockets in his zeal to get the treats. Then there is the squeaker, which he dispatched of in like 4 seconds (somehow without ripping the fabric(?)), then there are all sorts of crinkles and textures on both sides. All of this and the good stitching make it a toy he wants to play with but that he doesn’t annihilate in one day. The hard plastic toys are also good but I feel like I need to watch him carefully for fear that a sharp chunk will come off. The medium chew toys are cool but he’s just not into them. So this wins!

My dogs favorite toy!
Color: Blue & Yellow Eel Bundle
This is my Jack Chi and Yorkies favorite toys (it helps when they get 5 mini milk bones). It is a tough toy, but not impervious to a Jack Chi determination to remove all squeekiees! Squeekie or not, it's still their favorite toy for tug-a-war.

Fun Toy
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
My dog loves this toy. It has 2 squeaky & also has crinkly sound along with the slots for treats. However it is not very durable. The treat slots were pretty much destroyed with the first use. I'm still giving it a 4 star because it is so fun & entertaining for my GSD.

Kept puppy interested!... Till she chewed it apart in 5 minutes
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
I'll start off by saying this is a really unique toy. You really can hide treats in the pocket and the velcro is strong enough to roll it up that it won't come undone easily. The different textures and sounds interest my puppy! And she LOVES it! But it didn't last long with her. She LOVES rope toys and ripping them apart and eating it. I literally had just given it to her and not even a minute later (not joking), she had torn off a row of the rope-like part. 5 minutes later, the tail is already in shambles lol So long story short, great and interesting toy to keep the doggy from being bored. Maybe not so great for aggressive chewers/rippers in the long term. More than likely will be torn to shreds by the end of the day.

Great quality, fun design.
Color: No Stuffing Blue Eel
Wonderfully durable.. We have a 3 y/o australian kelpey and a 2 y/o pitty.. both are incredibly playful and tear up toys like nobody's business. A lot of the time under a day.. We're on day three with this eel, they love it and its holding firm (no tears or missing pieces). Squeakers are their favorite and these ones are perfect ( prominent but not too loud)
