BRF Mushroom Substrate Cakes, 1/2 Pint Organic Brown Rice Flour and Vermiculite BRF / PF Tek Jars, Modified Lid with Injection Portfor mushroom growing (mycology). 

Each jar of mushroom substrate is fully sterilized in our commercial autoclave.  BRF jars are the perfect growing medium for many species of mushrooms.  Inject your genetics through the grey injection port. 

Modified lid includes a gas exchange filter for proper oxygen levels.  Once your BRF jar is fully colonized the bake is turned out into your fruiting chamber and mushrooms will grow within a few days.  See our learning section for videos that show the process step by step.

This listing is for two jars.

Perishable, inoculate as soon as possible after receiving.
