Oyster Mushrooms On Coffee Grounds

Was headed out camping and walked by my  coffee grounds bucket, and was shocked by what I saw!

This what the project looked like in April.

I had been around this area earlier in the week and didn’t notice anything!

Beautiful luxurious Oyster Mushrooms! They are growing quite well, and I can’t wait to eat them. This marks a growing success for me, because this was the Oyster growing project I was most interested in.

Tons and tons of coffee grounds are wasted in our landfills each year. This proves that food can be produced using this waste product. Not only does it keep this valuable resource out of our landfills, but the mushrooms also neutralize the caffeine in the grounds.

Once again the process was low cost and not labor intensive. The spawn was just simply mixed into the coffee grounds and left to grow on it’s own. I can see a real use for these mushrooms in poor countries with shortages of food, and plenty of waste.

Thanks again to Wild Joe’s for the organic coffee grounds, and Garden City Fungi for the spawn.

Oyster Mushrooms On Coffee Grounds

I have wanted to inoculate coffee grounds with oyster mushrooms for quite awhile. With the help of the cool people at Wild Joe’s, I have managed to collect some great organic, free trade coffee grounds. The grounds are too rich to waste and the folks at Wild Joe’s  feel the same way! Oyster Mushrooms grow on almost anything, so it stands to reason they would like coffee grounds. The very strength of coffee grounds, is also their downfall.They are a perfect semi sterile substrate for growing fungus because they have been steam pasteurized. The problem with that is the quickest fungus to get to them is usually green mold. The trick to this project is going to be controlling the growing conditions to help the oysters while making the mold unhappy.When I first put the spawn in the coffee grounds, the spawn took off because it was warm in the garage and the spawn was hungry. Then I noticed the green mold creeping in, and as you see in the pictures, there is a major war going on between the mold and the oysters.

The little brown specks are the grain from the spawn mixture. The white spider web is the Oyster spawn growing and the green is, you guessed it, mold.At this point the project has gone outside,and neither the spawn nor the mold is happy! But I know the spawn is still growing as the temperature is just above freezing, and the mold won’t survive the cold.Hopefully the bucket will produce mushrooms. Either way the experiment has already told me that Oyster spawn does indeed like coffee grounds.

Thanx again to the awesome crew at Wild Joe’s for saving the grounds for me,and thank you Hannah for setting it up. Stop by their coffee house on Main Street in Bozeman and create some grounds for us.

Shiitakes for Food and Medicine

Shiitakes are a great way to eat your medicine.

ShiitakeShiitake mushrooms have proven to be an all around healthy food. The medicinal properties are almost as good as the Reishi, which is tasty but difficult to eat in volume.Western society has finally realized what eastern society has known for centuries. Mushrooms are good for you and have incredible healing properties for our ailing society.


It only stands to reason that you would want the shiitake to be organic. There is only a few places in the country to purchase them. Garden City Fungi, outside of Missoula, grows and sells organic mushrooms. The owners are serious about organics and I trust them for a safe local product. Stamets, of Fungi Perfecti,  is a champion of the organic mushroom movement, and I trust them for mailorder.

Lincs to both websites are on the Home Page. They are both certified organic. Support responsible growers and get to know your farmers.

Organic Mushroom Cultivation

Organic Mushroom Cultivation is critical for health and safety.

Most mushrooms concentrate, whether it is nutrients, minerals or toxins. They will grow on varied substrates so it becomes very important how and where your mushrooms grow. When using them for food it is important, but when using them for medicine, it seems crazy to put poison in your body when trying to heal! Organic is a good start, but it can be cheated, and I like to know exactly what my mushrooms have been exposed to.

Growing on trees and stumps seems organic and in most cases can be called organic, but it is necessary to know where these trees grow. Trees growing by busy roadways absorb toxins from exhaust as well as tires and brakes. Mushrooms then concentrate these toxins, and release them to the consumer. Substrates whether from farms or forest need to be scrutinized for contaminates.

Organic is a buzz word right now and I am glad people have been awaken to this worthy cause. Large agriculture and big business is in it for the money. They will grow on whatever is economically feasible, within our weak, and vague organic rules, to turn a buck. This should not be confused with what you or I consider to be organic, and safe.

The only safe way to know what you are eating, is to grow or pick it yourself. The only other way is to know your farmer, support them, and pay them well!
