BRF Mushroom Substrate - 12 Pack Half-Pint Jars - Organic Brown Rice Flour + Vermiculite

Mushroom Substrate

12 Half Pint Jars

Premium Organic Brown Rice Flour (BRF) + Professional Grade Vermiculite

These jars can be used to produce nearly any type of mushrooms or spawn (for bulk growing).

All jars are hydrated and sterilized via pressure cooker at 15 psi for 90 minutes and then shipped out within 12-24 hours. Lids come equipped with a self-healing injection port and also a breathable synthetic filter for clean gas exchange. 

In order to inoculate the jars you will need to obtain mushroom spores or a liquid culture (NOT INCLUDED). These can be found easily for purchase on the internet. Simply inoculate each jar with 2-4 cc's of your spore solution, or up to 10 cc's of liquid culture. Leave your jars in a dark place with the room temperature set between 68°-78°, until they are fully colonized.

It is always best to inoculate your jars ASAP. If you are unable to inoculate right away, they should be used within 7 days. If you need to wait longer than 7 days I recommend you refrigerate them until you are ready.
