Each Monster contains a sealed bag of oyster mushroom mycelium incubated over recycled coffee grounds. Its use is very simple, just open the window of the box, make a cut in the bag, immerse it in water 24 hours, put it back in the box and moisten the substrate daily. In a few days the first mushrooms will begin to sprout. From each kit it is possible to obtain up to 3 crops, which will be around 500gr in total. Once the crop is finished, the substrate is transformed into an excellent natural fertilizer that you can use in your pots or vegetable garden.
