Liquid Culture

Liquid culture is a nutritious solution that mycelium can grow on.  You can use it to store your species, create your own syringes and have a free long-term supply.

 

Key benefits of liquid culture: 

• Quicker grain colonisation time

• Longer shelf life

• Lower contamination risk

• Scalability - can create larger quantities

• More uniform and vigorous growth

• Reduces the need to buy spores syringes from vendors

 

You are 100% capable of creating your own liquid culture, give it a go today!

How To Create Liquid Culture

​

Equipment:

• Pre-made Liquid Culture Pouch (Our 100g pouch can create 25L !)

• Liquid Culture Jars

• Syringes + Needles

• Magnetic Stirrer 

• Stir Bars 

​

Our liquid culture kit contains all the above, view HERE: 

​

Additional Extras

• Pressure Cooker (we recommend the Hawkins brand available on Amazon)

​

Best Liquid Culture Recipe

​

1. Prepare Nutrient Solution

​

Mix 4g of Liquid Culture Pre-Mix per litre of distilled water.

Stir thoroughly to dissolve the malt extract completely.

​

​

2. Sterilise the Nutrient Solution

​

Pour the nutrient solution into your liquid culture jar, and add a stir bar. You can purchase a pre-made liquid culture jar HERE. 

Seal the container with a lid, and then place it in a pressure cooker.

Sterilize the nutrient solution at 15 psi for 15 minutes.

​

​

3. Cooling and Inoculation

​

Allow the sterilized nutrient solution to cool to room temperature before proceeding.

Using a sterilized needle, inoculate the liquid culture with a spore or mycelium solution. 

​

​

4. Incubation

​

Place the inoculated liquid culture in a warm, dark area for incubation (24-27°C).

​

​

5. Monitor and Spin

​

Regularly inspect the liquid culture for signs of mycelial growth. 

You can use a magnetic stirrer to distribute the mycelium throughout the solution or shake the container gently. 

Mycelium growth may take several days to a few weeks, depending on the species and conditions.

​

​

6. Harvesting and Use

​

Once the liquid culture is fully colonised with mycelium, it is ready for use. You can use a magnetic stirrer to mix the mycelium before creating your syringe

 

 

Best Liquid Culture Recipe

​

When stored in a refrigerator at around 4°C (39°F), liquid cultures can last for 6 months to a year refrigerated as it slows down the metabolic activity of the mycelium.
