Rye Berries

Rye Berries - OutGrow® is the leading provider for edible mushroom cultures and prepared substrates on the internet. We are a small company positioned in the glacial hills in the corner of Northwestern Illinois. All of us grew up here and our location is just a few miles from the dairy farm where our founder, Mike, grew up. We take pride in our rural roots and delight in bringing our Midwestern integrity and high quality products to the entire world from our little spot in the country.
