BRF JARS ™ Brown Rice Flour Based Mushroom Substrate. Buy Brown Rice Flour (BRF) Jar – Mushroom Substrate Online. Purchase online a jar of brown rice flour (BRF), a pre-sterilized mushroom substrate packaged in a half-pint (8 oz) myco jar. BRF substrate jars, made popular by the PF Tek, have shown to be an effective growing media for a wide variety of mushroom species. Each BRF jar contains a homogeneous mixture of sterilized organic brown rice flour, vermiculite, and distilled water. A thin coating of dry vermiculite is applied on top of the mixture to act as a barrier to pollutants.

The jars are sealed with a metal myco lid that has a 0.22m adhesive filter patch for gas exchange and a super-heavy duty self-healing injection port that makes inoculating jars almost foolproof. Each jar is individually wrapped in protective foil, which keeps the lid’s surface clean and dry until you’re ready to inoculate with your spore syringe or liquid culture.

Simply remove the protective foil from the top of the lid and place it in a clean, draft-free area to use. Then, push the sterile needle (use a fresh needle or flame sterilize if it is not new) of your spore syringe as far as possible through the orange injection port. Then, slowly depress the plunger of the syringe to inoculate 1-2cc of spore or liquid culture solution into the brown rice flour container. Remove the needle from its protective cap and store it for future use.

Once your BRF jar has colonized entirely with mycelium, you can transplant it to your desired fruiting chamber (i.e. a monotub). Empty myco jars can be cleansed and reused following birth.

BRF JARS ™ Brown Rice Flour Based Mushroom Substrate. Brown rice flour-based mushroom substrate, completely sterilized and packaged in convenient half-pint jars for simple inoculation.

While inoculating, use a circular motion with your needle to disperse the gourmet mushroom spore solution evenly. Additionally, BRF jars have a gas exchange filter, which eliminates the need for an additional layer of vermiculite. Once your BRF jar is completely colonized, you may birth the cake to the fruiting chamber of your choice. After birthing your cakes, you can also wash and reuse the jar and lid.
