Mushroom Grain Spawn Bag Instructions
Step 1: Inoculation and Colonization
- Start by unpacking the grain spawn and removing the protective wrap.
- Gently unfold the top flap to allow fresh air to flow through the 0.5 micron filter patch.
- Sterilize the grain spawn bag and injection site with isopropyl alcohol to minimize the risk of contamination.
- Prepare your spore syringe or liquid culture solution for inoculating the sterilized grain bags with your favorite spores or mushroom strain.
- Through the self-healing injection port, simply inject around 2-4 ccs of mushroom spore or liquid culture solution into the sterile grain bag. Avoid over-saturation.
- Do not mix the spawn after inoculation. Instead, rotate it gently to distribute the solution evenly through the sterilized grain spawn portion.
- Place the inoculated bag to incubate in a warm, dark location with an incubation temperature of approximately 65-75 (18-27°C) degrees Fahrenheit.
Step 2: Fruiting Stage in a Fruiting Chamber, Monotub, or Grow Tent
- Choose your preferred fruiting method: fruiting inside the bag or transferring to another fruiting container like a terrarium, plastic tote, fruiting chamber, or monotub.
- Mix the sterilized substrate and the colonized grain into your fruiting chamber, ensuring thorough and even distribution.
- Wait for 1-2 weeks in a dark environment until the bulk substrate block is 100% colonized.
- Provide the fruiting chamber with 8-12 hours of light per day and maintain a temperature range of 70-75°F and Relative Humidity of 85-90%.
- Give the fruiting chamber at least 3-4 fresh air exchanges (FAE) daily by removing the lid and using it to fan out the old air.
- Once the mushrooms or mushroom pins start to form, increase the humidity inside the mushroom fruiting chamber to around 95-100%, by misting the chamber and its contents more frequently.
- Monitor the progress and development of the mushrooms. After 7-14 days, your substrate block will be ready for harvest.
- Carefully harvest the mushrooms or mushroom pins by twisting or cutting them at the base, ensuring minimal disturbance to the remaining mycelium.
Spawn to Bulk Ratio
- We suggest using 1 lb of colonized grain spawn for every 5 lbs of sterile substrate, whether it be manure or hardwood. Additionally, for a 3 lb injection port bag, we advise using 2.5-5ccs. (For more comprehensive information on inoculation and colonization, please refer to the section above.)
Frequently Asked Questions
How to make spawn bags?
To create a spawn bag for cultivating mushrooms, one must first prepare the substrate by using sterilized grains or sawdust as a suitable medium.
The following steps can be followed to make a spawn bag:
- Fill autoclavable filter patch bags with the prepared substrate, leaving some headspace.
- Sterilize the filled bags through pressure cooking or autoclaving as per recommended guidelines for complete sterilization.
- Allow the bags to cool down entirely in a sterile environment before proceeding further.
- Securely seal the top of the bag using an impulse sealer to maintain sterility.
- Inoculate with spores or culture syringe, and place it in a warm, dark area for incubation.
How long does it take for mycelium to grow on grain?
The duration for the mycelium to fully colonize grain in organic sterilized mushroom spawn bags can vary depending on the species, with faster-growing varieties such as oyster mushrooms taking approximately 7-10 days, while slower-growing ones like shiitake may require 10-14 days or more.
This process involves the growth of mycelium, a network of fungal threads, in the sterilized grain bags.
Creating optimal conditions and using organic materials can promote healthier and faster mycelial growth.
How long for spores to germinate on grain?
Spore germination on grain can vary based on factors such as species and environmental conditions, with an average germination time of approximately 1-2 weeks after inoculation.
Quality spores should be used to ensure successful germination on the grain. Maintaining cleanliness throughout the cultivation process is crucial to ensure optimal results. Monitoring mycelium growth is crucial to track the progress of mushroom cultivation.
When to break up mycelium?
During the cultivation process, understanding when to break up mycelium is vital for achieving desired outcomes and optimal results. In the case of organic sterilized mushroom grain spawn bags, breaking up mycelium becomes relevant during the casing layer application stage. This step involves gently separating the mycelium to promote uniform fruiting. However, it is important to note that not all methods require this procedure, as species-specific requirements may vary.
Breaking up mycelium during this stage helps to distribute the mycelial network evenly throughout the casing layer, providing an ideal environment for fruiting bodies to develop. By following this practice, cultivators can ensure that their organic sterilized mushroom grain spawn bags yield consistent and successful results in mushroom production.
How long for mushrooms to fruit?
Successful fruiting of mushrooms depends on various factors such as environmental conditions and the specific species being cultivated. The use of organic sterilized mushroom grain spawn bags is a common method for initiating mushroom growth.
However, the time it takes for mushrooms to fruit can vary significantly. Fast-growing species like oyster mushrooms may begin to fruit within 2-4 weeks, while slower-growing varieties like shiitake can take 6-12 weeks or more.
Regular monitoring and proper environmental control are essential for optimizing fruiting in mushroom cultivation.
