Product description

The organic sterilized grain spawn bag was formulated by mycologists to maximize the speed and size of your mushroom grow. Each spawn bag contains our proprietary blend featuring hydrated, nutrient-rich, organic millet and wheat berries. Bags also include a self-healing injection port for use with a spore or culture syringe plus a 0.2 micron filter patch to block airborne contaminants while providing even gas exchange. Note: Color of injection port may vary.
USDA Certified Organic
Media = Organic wheat & millet mix
Bag weight = 3lbs 

We recommended 1 lb of colonized grain spawn for every 5 lbs of manure or hardwood sterile substrate. We also recommend using 2.5-5ccs per 3 lb injection port bag. (See Inoculation and Colonization below for full details.)


Why millet?

Millet has a much lower endospore load than rye and wheat, making it less prone to contamination. And its small size means your spawn will have many more inoculation points for the same volume of grain. By using millet, the mycelium will spread more evenly and abundantly through the substrate. And, as a high-nutrient medium, it also encourages rapid mycelial expansion.

Sterilization

North Spore grain spawn bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.

Inoculation

To inoculate the grain bag, simply inject your spore or culture syringe through the port in a sterile location. We always recommend clean hands and latex gloves to reduce the introduction of contaminants.

It is best practice to wait a minimum of 1 week after arrival before injecting grain bags to ensure they were not compromised during transit. Rest assured that your purchase is 100% guaranteed. If your bag was compromised, we will replace it. 

We recommend using 2.5-5ccs per 3lb injection port bag. We do not typically recommend using an entire syringe in one bag. Doing so adds excessive moisture which can create over saturation in the bag. This over-saturation can pool and is prone to being anaerobic and the mycelium will have a hard time colonizing.

Colonization

Allow your bag to colonize in a cool location out of direct sunlight. Temperature for incubation shouldn't exceed 75 degrees F or dip below 55 degrees F. After a couple weeks, you should start to see mycelium growing on the grain. 

You'll notice the white mycelium growing outward from the injection point. When it has grown three to four inches you should, without opening the bag, carefully break up the colonized grain and mix it into the uncolonized grain. This will dramatically speed up the colonization process.

When the bag is completely white with mycelium your spawn is ready to use. This may take a couple weeks to a month or more depending on the species and vigor of your culture.

Storing

Grain bags should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use.

I have just bought a couple orders of the newly upgraded bins and can only say .. Thank you for keeping up with this endeavor.. It is greatly appreciated
Fast Shipping and quick customer service keep Max Yield Bin on my radar as I expend my business

So I ordered a max yield bin and when I received it,there had been some damage to the lid during shipping. I contacted customer service and sent a few pictures and within a week I had a new bin on the way. It arrived perfectly fine. I still can't rate the actual product yet but the customer service is great.

3 full beautiful flushes! So easy. I didn’t have to do anything except harvest the bad boys. I don’t have to fan them every 4 hours. Worry about misting too much. I only bought 1 bin initially because the I thought the price was high. Now I understand and bought 3 more. Love love love.

Maxyield Bins are a great plug & play option—no need to spend time designing the perfect monotub because Maxyield Bins has already done it. This has allowed me time to focus on all of the other elements of mushroom cultivation. I highly recommend this product.

Got two sets of bins with the full setup of extras. One of the lids cracked in long shipment to the US, which they promptly replaced. The bins are good, sturdy quality and look great, so they must have withstood a beating during shipment to crack a lid. The next one arrived without issues in perfect condition. Thank you for the excellent customer service.

Phenominal product, it streamlined my production and I have had consistent incredible flushes using these bins. One order a bin was cracked I messaged and sent a couple pictures and they were on it with a new lid. Very impressed with these guys, definitely be ordering more bins soon
