What? A sealed bag of oyster mushroom mycelium incubated on coffee grounds.
Where? On the market – Spain.
More details: Its use is very simple, just start the window box, make a cut in the bag, immerse it in water 24 to 36 hours, put it back in the box and moisten the substrate of a newspaper. In a few days you will begin to sprout your first mushrooms. Once the cultivation has finished, the mushrooms would have turned the substrate into an excellent fertiliser that you can use in your pots or garden. It’s easy, fun and sustainable. You can grow your own mushrooms at home.
