What is sterilized grain spawn?
This is our most popular product that saves the grower 50% of their time! It eliminates the process of soaking your grains, boiling, drying, bagging and pressure cooking. This goes along with our Compost Substrate Soil bags which are a perfect ratio of 1 Grain to 2 Compost Soil when you buy them together.
Our Sterilized grain spawn is guaranteed 100% sterile. We have tried and tested hundreds of methods of sterilization and have the finest machinery possible from overseas to be able to produce these at such high quality. Our bags are composed of Sterilized grain in a specific grain recipe mix that we have discovered after years of trials, in a very think poly bag that has been pre-sealed and triple sterilized, it comes with hydrophobic filters installed on the bag for the perfect gas exchange allowance so your spawn gets the proper amount of CO2 and oxygen exchange. Mycelium thrive in a high CO2 environment but they still need the proper micro pore size to allow some gas exchange. But if you give it too much of either gas then the wait is long! We have got this down to an art and our filters allow no hydration in or out. That means the HO2 stays in your bags! Our bags create their own eco-environment, and they stay that way until they are fully colonized and ready to be opened. They even come installed with self-healing airtight injection ports for easy inoculation. Our bags are easy to massage and break up the mycelium as well once it starts colonizing. Try our grain bags with our Liquid Culture product which makes the colonization time super-fast.
Although we make these for the purpose of colonizing and then mixing in a mono tub, you can also consider growing directly from the bag after it has colonized. Another option is to drop more sterilized grains into your colonized grain bag which will quickly colonize the rest.
These Bags come in 2 pound unit sizes which are perfect ratio to use 3 bags per large mono tub.
The ratio for a 54 to 62 quart Mono tub is approx.:
6 pounds Colonized Grain
12 pounds Substrate compost
2 pounds Casing for top layer (some people use more if they want a thicker top layer)
INGREDIENTS: Always 100% non GMO and ORGANIC, triple washed and have no pesticides or chemicals ever near the product. This is very important! The product varies from season to season based on the best combination of organic grains available. Our favorite grain thus far for mycelium growth speed is wheat berries, but it is very important that it is NON GMO AND NOT SPRAYED! You will always find wheat berries as the bulk of our grain bags and seasonally mixed with additional nutritional grains such as, rye seed, quinoa, millet, barley, and oats.
It took us a lot of trial and error to get this perfect!
DIRECTIONS ON HOW TO INOCULATE A GRAIN BAG:
- Pre-installed 0.2 micron hydrophobic filter
- Pre-installed self-healing injection port
- Bags are much larger than the volume of grain so they have good airflow and gas exchange
- Grains are always non GMO and 100% Organic
- Specially formulated mixture of grains to offer maximum nutrients (appearance varies based on season)
- Bags have 2 pounds of grain each
- Guaranteed 100% Sterile
- Backed by many years of trials and testing, this is the best combination we have found.
- Cut your time of production down by 50%
- This product can be used for many methods of use (mono tubs, direct bag grow, grain dropping)
You should be doing the injection in a glovebox, or at the very least, a still-air environment. If you are going to work in open air, we suggest turning your AC/heater off an hour prior to inoculating your bags (this reduces the amount of airborne contaminants in the area). It is also recommended to work in a clean, small room with the door closed to prevent airflow.
Step 1: The first step of inoculating a grain bag is to prepare it for injection with spores or live mycelial culture. (Which we sell both) Carefully pull the gussets on the bag apart all the way up to the top of the bag, where it is sealed. You want to make sure to "inflate" the bag enough so the filter has some room to "breathe." If the filter is pressed up against the plastic of the bag, it will limit gas exchange during the colonization phase and could potentially stall the colonization process.
Step 2: Put your gloves on if you have not already. Wipe down the black self-healing injection port with a sterile alcohol swab
Step 3: Flame the needle of your syringe for 15 seconds. After flaming the needle, press the plunger of the syringe down slightly and squirt a small amount of solution out of the needle to cool it down. This step is best performed with the assistance of an alcohol burner because it will not leave any soot on your needle. If a lighter is used instead, wipe off any lighter soot that is left behind on the needle with a sterile alcohol swab immediately after flame sterilization.
Step 4: Carefully inoculate the bag through the self-healing injection port with 1-2 ccs of spore or culture solution. We prefer to use much more then this as it aids in faster colonization time. We use 5 to 10cc Liquid Culture in a 2 pound grain bag. But we also have access to ample supply. Most people simply use a few CC in each bag. Keeping in mind that Liquid Culture colonizes much faster than spore syringes.
Step 5: Place your bag in a place that is subject to minimum disturbances and will maintain a temperature between 75 and 81°F. It doesn't matter if it is dark or light but never put it in direct sunlight. You should see signs of growth 3-10 days after inoculation depending on if you used spore syringes or Liquid Culture which is faster. Try your best to disturb the bag as little as possible during this time period. You want the bag in an upright position (not rolled up) with ample space between the filter and the plastic of the bag so it can breathe during this critical colonization time period.
Step 6: After approximately 1-4 weeks (depending on what you used to inject the bag and how much you used), the mycelium will have colonized 70-75% of the bag.
Step 7: At this point of colonization (70-75%), break the grain up with your hands through the outside of the bag. This will distribute the mycelium and speed up the last phase of colonization. Do not perform this step until mycelial colonization has reached a minimum of 70%, doing so can stall growth.
Step 8: The mycelium will take a few to several days to recover from getting broken up and should colonize 100% of the bag in a few days after the prior (breaking up mycelium) was performed. Once you reach this point, it is now time to spawn the colonized grain to a bulk substrate like our Compost Soil.
