Step 1: Preparing Your Bags
-
Unbox immediately upon arrival and remove rubber bands Â
-
Expect 5-10% burst grains on outside - this is normal.
-
Loosen gussets for airflow and stand bags up.
-
Let rest for 7-10 days before use.
-
If issues arise, contact us with video and unused port.
Step 2: Inoculation Process
-
Sanitize injection port.
-
Inject 2-10 cc/ml liquid culture (no spore syringes).
-
Sterilize needle between injections with mini torch.
-
Massage bag to distribute inoculant.
-
To promote optimal airflow through the air filters, be sure to loosen the gussets. Skipping this step can severely hinder growth and restrict mycelium development. Simply pull the gussets apart and gently tug the bag from both ends to separate the filter from pressing against the opposite side. Do not skip this step as it will inhibite mycelium growth Â
Step 3: Storage
-
Keep at 70-75°F in open-air environment.
-
Avoid using incubators, seedling mats, airtight containers or tubs, as these devices can easily overheat or dry out your grain, potentially harming or killing your mycelium. Instead, store your culture at room temperature, ideally between 70–75°F.
Step 4: Monitoring
-
Expect growth in 7-14 days.
-
At 30% growth, gently mix to distribute mycelium.
Step 5: Final Steps
-
After 100% colonization, wait one week before spawning.
Step 6: Choose Your Substrate Method
Once your grain is fully colonized, you have two excellent options for spawning. Simply click your preferred method below:
- Fruiting Bags: We offer easy-to-use 2-pound and 3-pound fruiting bags that require minimal prep. For our 2-pound bags, mix in about 1 pound of grain spawn; for our 3-pound bags, use approximately 1.5 pounds. Click here to order.
- Mono Tub: Our recommended mono tub is the Sterilite 54 Qt Gasket Box, ideal for fruiting. We suggest using a ratio of 2-3 x 3-pound bags with 10 pounds of our aPlusRabbit substrate. Click Here to order.
Important Notice:
To ensure sterility, we recommend following our storage guidelines: place bags on a clean shelf for 7-10 days, avoiding storage in shipping boxes or sealed containers. This allows for proper observation of the bags' condition.We stand behind our products with a comprehensive 60-day replacement policy from the date of purchase. If you encounter any issues prior to inoculation, we offer a 100% replacement guarantee. Simply send us a video documenting the problem, along with a clear view of the unused injection port.Please note that once bags have been inoculated with an external culture, we cannot offer replacements or refunds. To maximize success, we strongly advise verifying cultures on agar before use and adhering to strict sterile inoculation practices. By following these guidelines, you'll be well-positioned to achieve optimal results with our supplies. Your satisfaction and success are our top priorities
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
These guys are the best. Good grains and great prices.
