Our top-performing organic sterilized grain spawn bag, meticulously crafted by experienced mycologists to optimize both the speed and yield of your mushroom cultivation. All you need is a spore syringe or liquid culture to kickstart your growth journey!

Achieve the ideal spawn to bulk ratio by using 1 lb of colonized grain spawn for every 5 lbs of manure or hardwood sterile substrate. For optimal results, we recommend applying 2.5-5ccs per 3 lb injection port bag. Explore the Inoculation and Colonization sections below for comprehensive instructions.

Inoculation

For a successful inoculation of the grain bag, simply introduce your spore or culture syringe through the designated port in a sterile environment. We strongly advocate for the use of clean hands and latex or nitrile gloves to minimize the risk of introducing contaminants.

As a best practice, we advise waiting a minimum of 1 week after receiving your order before injecting the grain bags. This precaution ensures that the bags were not compromised during transit. Be confident in your purchase; we guarantee it 100%. In the rare instance that your bag was compromised, we will promptly replace it.

Optimal results are achieved by using 2.5-5ccs per 3lb injection port bag. It's important to note that we do not recommend using an entire syringe in one bag. This precaution is taken to avoid excessive moisture, which can lead to over-saturation within the bag. Over-saturation may result in pooling and create an environment prone to anaerobic conditions, making it challenging for the mycelium to colonize effectively.

Colonization

Facilitate optimal colonization by allowing your bag to incubate in a cool environment away from direct sunlight. Maintain a consistent temperature between 55 to 75 degrees Fahrenheit during this incubation period. It's crucial to avoid temperatures that exceed 75 degrees F or dip below 55 degrees F.

After a few weeks, observe the emergence of mycelium as it extends outward from the injection point. Once the mycelium has reached a length of three to four inches, take a significant step in the process. Without opening the bag, delicately break up the colonized grain and blend it thoroughly with the uncolonized grain. This strategic action significantly accelerates the colonization process.

Monitor the bag closely, and when the entire substrate is adorned with a uniform white mycelial network, your spawn is ready for use. The duration for this transformation may vary, typically spanning from a couple of weeks to a month or more. The specific species and the vigor of your culture contribute to the timeframe. Rest assured, patience during this crucial phase will be rewarded with a robust and fully colonized substrate ready for the next stage of your mushroom cultivation journey.
