Brown Rice Flour (BRF) Jar Mushroom Substrate


SKU: N/A Categories: ,


Brown rice flour (BRF) pre-sterilized mushroom substrate in a half-pint (8 oz) glass mason jar. Popularized by the PF Tek, BRF substrate jars have proven to be an excellent growing medium for many different mushroom species. Our BRF jars are filled with a homogeneous mixture of sterilized organic brown rice flour, vermiculite, and distilled water. The mixture is topped with a thin layer of dry vermiculite that functions as a barrier to contaminants. The jars are sealed with a metal myco lid that features an adhesive 0.22µm filter patch for gas exchange and a super heavy duty self-healing injection port that minimizes contamination risks. Each jar comes individually wrapped in protective foil which keeps the lid's surface dry and free of contaminants until you are ready to inoculate with your spore syringe. The glass jar can be washed and reused.
