How to Use BRF Mushroom Substrate Jars 12-Pack

Preparing Your Workspace

Before you begin working with the BRF Mushroom Substrate Jars 12-Pack, it’s important to set up a clean and sanitized environment. Although a laminar flow hood or still air box is ideal for preventing contamination, you can work effectively by following a few essential cleanliness practices. Here’s what you need to do:

• Disinfect your work area thoroughly with rubbing alcohol or a similar sanitizer.
• Avoid rooms with airflow from fans, air conditioners, or furnaces to minimize airborne contaminants.
• Use a surface without carpeting, as carpets tend to release dust particles into the air when walked on.
• Before handling your BRF jars, wipe them down with rubbing alcohol using a paper towel.
• Sanitize your hands and all tools, such as syringes, to reduce contamination risk.

Working in a clean environment is crucial to ensure the success of your mushroom cultivation. If you don’t have access to a laminar flow hood, consider using a still air box. This simple tool limits airflow in your workspace, reducing the chance of contaminants entering your substrate during inoculation.

What You Need for Inoculation

To begin inoculating the BRF Mushroom Substrate Jars 12-Pack, gather the following supplies:

• BRF Mushroom Substrate Jars 12-Pack
• Spore syringe or liquid culture from a reliable source
• Flame source (spirit lamp is recommended)
• Rubbing alcohol, paper towels
• Optional: Gloves to keep your hands clean

A spirit lamp is highly recommended for sterilizing your needle. Lighters can create soot on the needle, which could lead to contamination. Always keep rubbing alcohol and flame sources far apart to avoid fire hazards, and work in a well-lit space to ensure precision during inoculation.

Step-by-Step Guide to Inoculating BRF Mushroom Substrate Jars

1. Sterilize the Needle

First, ensure your syringe needle is properly sterilized by holding it over the flame of your spirit lamp until it turns red hot. After heating, allow the needle to cool for about 30 seconds to 1 minute before injecting. Avoid using rubbing alcohol to cool the needle, as this can introduce contaminants.

2. Inoculate the BRF Jars

Insert the sterilized needle into the self-healing injection port of each jar. For each jar, inject 2-4cc of spore solution or liquid culture into the substrate. Distribute the liquid evenly by tilting the jar to ensure the spores reach different areas of the substrate.

3. Swirl and Distribute the Spores

After inoculating, gently swirl each jar or tap the sides to help the liquid culture distribute evenly. This helps ensure uniform colonization throughout the jar and promotes faster mycelial growth.

Incubation Process for BRF Mushroom Substrate Jars

Once inoculated, place the jars in a location with stable temperatures between 65-75°F. You may choose to incubate the jars at up to 80°F, but higher temperatures should be avoided, as they can slow down colonization or encourage contamination.

Keep the jars upright at all times, as the filter patch at the top is designed for proper gas exchange. It’s critical not to block the filter patch with other jars or materials, as this will inhibit the growth process. If incubating in a dedicated chamber, monitor the temperature closely to avoid overheating.

Depending on whether you’re using spores or liquid culture, you should start seeing mycelial growth within 10-14 days. Full colonization typically takes 3-4 weeks with spores, while liquid culture may reduce this time by about a week.

Fruiting or Using the BRF Jars as Spawn

Once your BRF jars are fully colonized, you can choose to:

• Fruit the Jars as Cakes: The BRF jars can be fruited directly as cakes inside a fruiting chamber. This is a great method if you want to keep the process simple. To do this, remove the colonized substrate from the jars and place them in a fruiting chamber, ensuring the environment is humid and has proper air exchange. Mist the cakes lightly each day and fan the chamber for fresh air.
• Use as Spawn: Alternatively, you can use the colonized BRF jars as spawn by transferring them to a secondary substrate such as manure or wood. This allows the mushrooms to grow larger due to the extra nutrients in the secondary substrate. To transfer the BRF cakes, break them up gently and mix them into the secondary substrate inside a clean environment. Seal the bag and wait for further colonization.

Fruiting directly from the jar is simpler and faster but may yield smaller mushrooms. Using the jars as spawn will result in larger flushes but requires additional steps with secondary substrates. Choose the method that best suits your growing needs.

Monitoring and Contamination Prevention

Keep an eye on the jars during colonization. Signs of contamination, such as strange colors or slimy textures, should be addressed immediately. If contamination occurs, discard the affected jar to prevent it from spreading to your other projects. Remember that green, black, or orange mold is a strong indicator of contamination, and the jar should be safely disposed of.

Maximizing Yield and Efficiency

To maximize your mushroom yield, consider pairing the BRF jars with a secondary substrate, as this allows for larger flushes and higher-quality mushrooms. If you’re growing multiple strains, using each jar for different types of mushrooms can also help you experiment with different growth patterns and yields.

Consistent room temperatures, proper air exchange, and maintaining high humidity levels in your fruiting chamber will result in optimal yields. A consistent growing environment will speed up the fruiting process and improve overall quality.

Conclusion

The BRF Mushroom Substrate Jars 12-Pack offers an excellent, beginner-friendly way to start cultivating mushrooms. By following these steps for inoculation, incubation, and fruiting, you’ll be on your way to harvesting healthy, robust mushrooms, whether you fruit directly or use the jars as spawn. With proper care, you can enjoy multiple flushes and maximize your mushroom yields.
