POOR BOY SUPER PASTEURIZATION TEK, 20% Bran Success

Introduction

This tutorial outlines the process of achieving successful mushroom cultivation using a low-energy pasteurization method known as poor boy super pasteurization. This technique is particularly effective for substrates with 20% bran and is designed for those looking to enhance mushroom yields sustainably. We'll cover the necessary steps to implement this method based on insights shared in the video.

Step 1: Prepare Your Substrate

To begin, you need to prepare your substrate mixture.

• Choose your base substrate (e.g., straw, sawdust).
• Add 20% bran to the substrate. This supplementation helps provide extra nutrients for the mushrooms.
• Mix the substrate and bran thoroughly to ensure even distribution.

Step 2: Moisture Content Adjustment

Proper moisture content is critical for successful pasteurization.

• Aim for a moisture level of around 60-65%.
• Use a moisture meter to check levels, or perform a squeeze test:
  • Take a handful of the substrate and squeeze it.
  • If a few drops of water come out, it's at the right moisture level.

Step 3: Packing the Substrate

Once your substrate is ready, it's time to pack it for pasteurization.

• Fill your containers (e.g., bags, jars) with the substrate mixture.
• Avoid overpacking, which can impede proper pasteurization.
• Leave some space at the top for expansion.

Step 4: Set Up Pasteurization Environment

Prepare your pasteurization setup.

• Use a cooler or large container filled with water to create a water bath.
• Heat the water to around 160°F (71°C) for effective pasteurization.
• Place the packed substrate containers into the cooler, ensuring they are fully submerged.

Step 5: Prolonged Pasteurization

This step is key to achieving optimal results.

• Maintain the water temperature at 160°F for 60-90 minutes.
• Use a thermometer to check the water temperature regularly.
• This prolonged exposure helps eliminate contaminants while preserving beneficial microbes.

Step 6: Cooling and Inoculation

After pasteurization, allow your substrate to cool before inoculation.

• Remove the containers from the cooler and let them cool to room temperature.
• Inoculate the cooled substrate with your chosen mushroom spores or spawn.
• Work in a clean environment to prevent contamination.

Step 7: Incubation

Post-inoculation, provide the right conditions for mushroom growth.

• Place the inoculated substrate in a dark, warm area (around 70-75°F).
• Monitor humidity levels; consider using a humidity tent or bag.
• Wait for mycelium to colonize the substrate fully.

Conclusion

By following these steps, you can effectively implement the poor boy super pasteurization method for mushroom cultivation, particularly with a 20% bran substrate. This technique not only supports sustainable practices but also enhances yields. As you gain experience, consider experimenting with different substrates and blends, such as soy hulls. Happy cultivating!
