BRF Bags
(Brown Rice Flour Mushroom Substrate)

This sale is for 1 bag
These bags contain 8 ounces of brown rice flour and vermiculite mushroom substrate, which is much more than others sellers use in their half pint jars. The bags do have self healing injection ports.
Simply inoculate the bag with 2-4 cc of your gourmet mushroom spore solution, or 5-8 cc of liquid culture, and let it grow.

OutGrow®'s Brown Rice Flour mushroom substrate mix is 100% sterilized and ready-to-use at your front door. The substrate has a light consistency after it is broken up, so that it is very easy for mycelium to colonize. This mushroom substrate is enhanced with all necessary nutrients and moisture needed for healthy, large fruits. The substrate contains vermiculite, brown rice flour, multigrain flour and gypsum.

There are no fragile, heavy glass jars to ship; that is why our shipping and production cost is much lower than those using jars. Our bags have a 0.5 µm filter patch for proper gas exchange, while keeping contaminants out.
You can fruit in vitro in the bag, or in a fruiting chamber, as you would a standard substrate cake. Nothing could be easier. Just inoculate and wait.
For larger grows, these BRF bags can also be used as spawn for a bulk substrate. Normally from inoculation to fruiting is around 4-5 weeks. This mushroom substrate is one of the finest available. These bags are suited for the beginner and advanced mycologists.
