If you’re ready to take your mushroom cultivation journey to the next level, learning how to make a spore syringe is an essential skill. A spore syringe is a sterile solution containing mushroom spores suspended in water, used to inoculate a substrate for growing mushrooms. It’s an affordable and effective way to start growing your own fungi at home. In this guide, we’ll show you exactly how to make a spore syringe and provide tips to ensure a contamination-free process.
What Is a Spore Syringe?
A spore syringe is a tool that mycologists and mushroom cultivators use to transfer spores to a growing medium. The syringe contains a mixture of water and spores, which, when injected into a sterilized substrate, germinate and begin forming mycelium—the foundation for mushroom growth.
Supplies You’ll Need
- A sterilized spore print (check out our spore print product pages if you need one)
- A sterile syringe (10-20 ml)
- Sterile water
- A shot glass or small container (sterilized)
- A flame source (like a lighter or alcohol burner)
- A pair of gloves (optional but recommended for cleanliness)
- A clean workspace (preferably a still-air box or glove box for sterility; learn how to make one here)
Step-by-Step Instructions for Making a Spore Syringe
1. Sterilize Your Workspace
Cleanliness is crucial when working with spores. Sterilize your workspace by wiping down surfaces with alcohol or a disinfectant. If you have access to a still-air box or glove box, use it to minimize airborne contaminants. Not sure how to make one? Check out our guide on how to make a still-air box.
2. Prepare Sterile Water
If you’re using pre-sterilized water, you can skip this step. Otherwise, boil water for at least 10 minutes to kill any microorganisms. Allow it to cool completely before use. Do not use tap water without sterilizing it first, as it can introduce contaminants. Personally I use distilled water for making spore syringes.
3. Extract the Spores
Using the sterilized gloves and sterile scalpel, gently scrape a small portion of the spore print into a sterilized shot glass or small container. Only a tiny amount of spores is needed, as they are microscopic and highly concentrated. Need help making a spore print? Check out our guide on how to make a spore print.
4. Draw Sterile Water into the Syringe
Using the sterile syringe, draw up the cooled, sterilized water. Fill the syringe about three-quarters full, leaving some space for the spore mixture.
5. Mix the Spores with Water
Inject a small amount of water from the syringe into the shot glass containing the spores. Gently swirl or stir the mixture to ensure the spores are evenly suspended in the water.
6. Fill the Syringe with the Spore Solution
Carefully draw the spore-laden water back into the syringe. Ensure that the solution is evenly mixed and free of visible clumps. Cap the syringe to keep it sterile.
7. Store the Spore Syringe
Label the syringe with the mushroom species and date of preparation. Store it in a cool, dark place (such as a refrigerator) until you’re ready to use it. Spore syringes can typically be stored for several months if kept properly.
Tips for Success
- Use a still-air box or glove box: These tools greatly reduce the risk of contamination by limiting exposure to airborne particles. Learn how to make one here.
- Flame sterilize the needle: Before each use, pass the syringe needle through a flame until it’s red-hot. Allow it to cool before injecting.
- Work quickly and efficiently: Minimize the time your materials are exposed to open air to reduce contamination risks.
Why Make Your Own Spore Syringe?
Making your own spore syringe has several advantages:
Cost-effective: You can produce multiple syringes from a single spore print, saving money over time.
Customization: Create spore syringes from specific mushroom strains or species that interest you.
Learning opportunity: The process helps deepen your understanding of mushroom cultivation and mycology.
