How to Use Rye Berry Mushroom Substrate Grain Jar - 1qt

Preparing Your Workspace

Before using the Rye Berry Mushroom Substrate Grain Jar - 1qt, it’s important to create a clean and sanitized environment to reduce contamination risks. Although using a laminar flow hood or still air box is ideal, you can still minimize contamination by following these steps:

• Disinfect your workspace thoroughly with rubbing alcohol or another sanitizing agent to remove dust and contaminants.
• Avoid working in areas with airflow from fans, air conditioners, or heaters, as these can introduce airborne particles.
• Wipe down the outside of the jar with rubbing alcohol before handling it to ensure a sterile surface.
• Sanitize your hands and any tools, such as syringes or scissors, before handling the jar.

Maintaining a clean workspace is critical for successful inoculation. If you don’t have access to a laminar flow hood, consider using a still air box to limit airborne contamination during inoculation.

Inoculating the Rye Berry Substrate Jar

1. Sterilize the Syringe Needle

Flame sterilize the syringe needle by holding it over a flame until it turns red hot. Allow the needle to cool for about 30 seconds to 1 minute before inoculating. This step helps prevent contamination during inoculation.

2. Inject the Spores or Liquid Culture

Insert the cooled needle into the self-healing injection port on the jar lid. Inject 4-6cc of spore solution or liquid culture into the substrate. Spread the inoculant evenly by injecting into different areas of the jar to ensure uniform colonization of the rye berries.

Incubating the Rye Berry Substrate Jar

Once inoculated, place the jar in an upright position in a room-temperature environment (65-75°F). Keep the jar away from direct sunlight and temperature fluctuations. You may incubate the jar at temperatures up to 80°F, but avoid going higher to prevent stalling the mycelium’s growth.

Ensure that the 5-micron filter patch on the jar remains unobstructed during incubation to allow proper gas exchange. You should begin to see mycelial growth within 10-14 days, with full colonization typically taking 3-4 weeks when using spores. Liquid culture may reduce colonization time by about a week.

Using the Substrate for Spawn

Once the rye berry substrate is fully colonized, it’s ready to be used as spawn. Grain spawn is not intended for direct fruiting but is designed to inoculate nutrient-rich bulk substrates, such as manure or wood. Here’s how to proceed:

• Transferring to a Secondary Substrate: Break up the fully colonized rye berries by gently shaking or tapping the jar. Once the grains are loosened, the spawn can be transferred to a secondary substrate to produce larger flushes of mushrooms.
• For best results, use 1 quart of spawn to inoculate up to 5 pounds of secondary substrate. This ensures even colonization and healthy mushroom growth.

Monitoring for Contamination

Although the Rye Berry Mushroom Substrate Grain Jar is fully hydrated and sterilized, contamination can still occur if cleanliness isn’t maintained. Watch for unusual colors, slime buildup, or foul odors, as these are signs of contamination. If contamination occurs, discard the jar and sanitize your workspace before starting a new batch.

Maximizing Spawn Efficiency

To ensure your grain spawn fully colonizes and is ready for transfer to a secondary substrate, make sure the filter patch remains unobstructed to allow for proper gas exchange. Maintaining a consistent temperature and a clean environment will promote healthy mycelial growth.

Once your grain spawn is fully colonized, transferring it to a nutrient-rich bulk substrate, such as manure or wood, provides the necessary nutrients for producing large mushroom flushes. Using 1 quart of spawn to inoculate up to 5 pounds of secondary substrate ensures even colonization and optimal mushroom growth.

Conclusion

The Rye Berry Mushroom Substrate Grain Jar - 1qt is a reliable and nutrient-rich medium for producing grain spawn. By following these steps, you’ll ensure successful colonization, allowing you to transfer the spawn to a secondary substrate for optimal mushroom growth. With proper care, you can enjoy multiple flushes of healthy mushrooms.
