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.

Oysters on Cornstalks Update

I was checking on my mushroom beds and thought I should check on my cornstalk project. This project (check former posts on cultivation) was an experiment to see if oyster mushrooms could be grown on cornstalks cheaply with minimal work. The project started out in a tub in my garage and got booted outside because of fungus gnats. It had already fruited proving that it is feasible. The project was outside in the cold and snow when the tub, cornstalks and all , was tipped over in a snow bank. After the snow left, the tub was removed and the project was left to the elements. It did not look very good, but was left to see what it would do. The weather has cooled a little, and the wild oysters are flushing, so it is a good time to check on oyster projects.

As you can see, it is hard to get a good mushroom down! These were a little past prime, but they survived, and the pile will be used to start some other projects. Notice that it looks like something else found them before I did. Those sure look like bite marks on the close up!
