Premium Oat-Wheat Grain Bags
Our top-selling grain bags for 5 years. Wheat provides fast colonization, while the oat blend creates an ideal grain spawn.
- Add our Drippy Nutrient Boost for fast colonization! It is our blend of azomite and Light Karo Corn Syrup
Instructions:
1. PREPARE THE BAGS
- Remove the bags from the boxes immediately upon receiving them. Do NOT store bags in boxes or sealed containers long term. They will incubate and often go bad. Do not store in refrigerators. Bags will arrive vacuum-tight as they were pre-sealed before sterilization.
- There will also at times be a few burst grains on the most outer parts of the bags, this is completely normal as we pre-seal all of our bags before sterilization, and the weak outer shell of both grains causes this.
- If the bags are wrapped in a rubber bands, remove them.
- Unroll the bags, loosen gussets so that air can easily pass through the filter to the grain.
- The injection port will be on the top side of the bag. By injecting on the top side of the grain, fast colonization of the selected culture will be achieved
2. ALLOW AIR FLOW
- Ensure gussets are loosened and prop the bag upright.
- Let the bag sit for at least 6 hours to allow air to flow through the filter.
- This will make the bag easier to massage and loosen, improving air flow for faster colonization.
4. CONFIRM STERILITY (OPTIONAL)
- For best results, store the bags for 7-10 days to confirm sterility. Store bags at a room temperature of 70-75 Fahrenheit
- During this time, perform an agar test to verify the culture is sterile.
5. INOCULATE
- Sanitize the injection port with an alcohol wipe.
- Inject 2-10 cc/ml of liquid culture.
- Be sure to sterilize your needle in between inoculations with a mini torch, never a lighter.
- Store the bags at 72-78°F, avoiding heating mats or incubators.
- Store bags on a clean shelf, never in incubators, tubs, or containers of any sort. They will need open air exchange to properly colonize
- Expect visible growth within 7-14 days, depending on the species and conditions.
- Once 30% growth is evident, gently mix the bags to distribute and break apart the mycelium. Keep grain away from filter
- Wait until the bags are fully colonized before spawning to your desired substrate.

United StatesQuality bags!
I made the switch to APlus grain bags a few months ago and haven’t looked back. My results speak for themselves! Before using these bags I had little to no success. The first time I used them I was rewarded with great results and have continued to get them. Definitely worth trying these products!!! The owner/operator is also very easy to communicate and work with if you need any help.
Great Company
