Brown Rice Flour (BRF) TEK Guide for Mycology

Dive into the world of mycology with the classic staple: Brown Rice Flour (BRF). Esteemed for its simplicity and efficacy, BRF paves the way for aspiring mycologists aiming for thriving fungal cultures.

The allure of BRF is its universal appeal. For novices, it offers an uncomplicated initiation into the vast realm of fungi. Meanwhile, seasoned mycologists appreciate BRF for its reliability and consistent outcomes.

INTRODUCTION:

This ever-evolving guide is dedicated to guiding your endeavors with BRF as a substrate. Embrace this journey as we unravel the necessary tools, ingredients, and procedures to transform your BRF substrate into a thriving fungal paradise.

MATERIALS NEEDED:

Note: Gypsum and Karo syrup are optional, but they enhance texture and nutritional content.

PROCEDURE:

Mixing:

  • Combine the Brown Rice Flour, vermiculite, and water in a mixing bowl.
  • For added benefits, mix in gypsum and Karo syrup.

Jar Preparation:

  • Fill each mason jar with the BRF mixture, leaving about a half-inch of space at the top. This space will be filled with dry vermiculite to act as a contamination barrier.

Topping Off:

  • Add dry vermiculite to the top half-inch of each jar, ensuring a protective layer against potential contaminants.

Jar Sealing:

  • Securing Lids: When placing the lid, ensure the rubber seal faces upward. This helps prevent the jars from getting vacuum-sealed during the sterilization process. Another option is to use a mycology lid such as one that contains a filtered vent and/or injection port (we have articles, DIY Supplies, and both Free & Paid for Mycology Courses hosted on our 🍄 Mushroom Academy!
  • Foil Cover: Wrap the tops of the jars with aluminum foil. This provides an added layer of protection against potential moisture intrusion during pressure cooking.

Jar Filling:

  • Filling: Load the jars with the Millet mixture with the correct amount of Millet.
  • PLEASE NOTE: If you followed our recipe (shown above) you shouldn’t have to worry about this however, ensure you leave about a 1-inch gap at the top to facilitate room for expansion and air exchange.
  • Securing Lids: When placing the lid, ensure the rubber seal faces upward. This helps prevent the jars from getting vacuum-sealed during the sterilization process. Another option is to use a mycology lid such as one that contains a filtered vent and/or injection port (we have articles, DIY Supplies, and both Free & Paid for Mycology Courses hosted on our 🍄 Mushroom Academy!
  • Foil Cover: Wrap the tops of the jars with aluminum foil. This provides an added layer of protection against potential moisture intrusion during pressure cooking.

Sterilization:

  • Using a pressure cooker, sterilize jars at 15 PSI for 90-minutes.
  • If using a large pot, boil jars for 90-120 minutes.
  • Once done, allow jars to cool overnight in the cooker or pot.

Inoculation:

  • Following your preferred method, inoculate each jar.
  • Replace the foil and store in a dark, warm place.

ADDITIONAL INSIGHTS & TIPS:

Benefits of BRF Tek:

  • The BRF Tek is particularly favored for its simplicity and effectiveness, making it an excellent choice for beginners in mycology.

Texture of the Mix:

  • It’s essential to achieve the right consistency with your substrate mix. It should be moist but not dripping wet. If you can squeeze a handful and only get a drop or two of water out, it’s perfect.

Contamination Watch:

  • BRF jars should show clean, white mycelial growth over time. Any odd colors or smells can be indicative of contamination. Regularly inspect your jars.

Ideal Genetics for BRF Tek:
Given the nutritious nature of the BRF substrate, various mushroom strains thrive with this method, including:

  • Golden Teacher (PC-Strain): Recognized for its steady growth and aesthetic appeal.

  • Cambodian (PC-Strain): Renowned for its fast colonization rate.

  • Mazatapec (PC-Strain): Another strain known for vigorous growth and distinctive fruit bodies.

Inoculation Best Practices:

  • Sterility is paramount. When inoculating your BRF jars, it’s recommended to work inside a Still Air Box (SAB) or under a Laminar Flow Hood to minimize contamination risks.

Complete Colonization:

  • Before moving to fruiting conditions or performing grain-to-grain transfers, ensure your substrate is 100% colonized. This typically results in the entire jar appearing white with mycelium.
