Growing mushrooms with coffee grounds: mushroom cultivation techniques, can mushroom dregs be used repeatedly

Today's coffee shops produce more coffee grounds every day, so some people find that coffee grounds can grow mushrooms, which can be used. Coffee grounds are an excellent medium for growing mushrooms (especially for Pleurotus ostreatus), thanks to the process of brewing coffee, which has helped sterilize the media and is rich in nutrients. Can mushroom residue be used repeatedly? It is not allowed, there is no nutrition.

500 grams of mushroom bags, equivalent to 2.5 kilograms of fresh coffee grounds. To get so many fresh coffee grounds (left over from brewing coffee that day), the next step is to grow mushrooms in containers-preferably in a growth bag with a filter, which can usually be bought with mushroom bags. If not, you can use a large sealed bag or a cleaned milk box, or an ice cream box with four small holes around it.

Wash hands thoroughly with antibacterial soap, then mix mushroom bags into coffee grounds and crush them with both hands to ensure uniform distribution. Put the inoculated coffee grounds in a plastic bag or container and remember to seal them.

Keep the bag or container in a warm, dark environment at a temperature of about 18-25 ℃, in a fume hood or sink. Leave it there for about three weeks until it is completely white-a symbol of the mycelium growing in the coffee grounds.

Once the mixture in the bag or container is completely white, place it in a bright place to avoid direct sunlight, and then cut a 5x5 centimeter hole at the top. Sprinkle the mixture in the container twice a day to prevent drying-mushrooms do not grow well in dry conditions.

In the next five to seven days, the little mushrooms will come out. Keep sprinkling water, they may grow twice as long every day. When the mushroom hat has been turned up a little, it can be harvested.
