How To Grow Mushrooms

How To Grow Mushrooms. Cultivating your own mushrooms can be enjoyable, enlightening and may give your immune system a boost. Buy a kit with the materials you need or gather straw, small logs or wood chips and add purchased “spawn” — vegetative mushroom tissue — grocery-store mushrooms or wild mushroom cuttings. Oyster, shiitake and morel mushrooms are among the easiest to grow. A healthful crop, mushrooms contribute protein and antioxidants to your diet.

Growing mushrooms on the Ground or in Containers

To grow mushrooms in a shady bed, spread a 9-inch layer of finely ground, dampened hardwood chips. Hay, leaves or compost can be used as alternative growing mediums. Bury chunks of mycelium, purchased or cut off mushrooms from the grocery store or the wild, among the chips. It will grow through the medium, extracting the nutrients it needs, while decaying the wood or leaves. Wood chips may also be piled in planter boxes or containers to support the growth of mycelium planted there. Be vigilant about keeping the containers shaded and moist, as these fungi will dry out more quickly than those in a flowerbed.

Growing mushrooms Indoors

Growing oyster mushrooms involves plastic bags filled with prepared straw. First, chop the straw to break its waterproof coating. Pack it into a 5 gallon container and add boiling water to cover. After sitting for 45 minutes, drain and let cool to room temperature. Next, mix in enough commercial spawn to equal 10 percent of the weight of the straw. Pack the mixture into one or more clear plastic bags and seal with packing tape. Punch holes in the bag about six inches apart, using a 16-penny nail. Store in a dark place at about 70 degrees Fahrenheit until the straw is fully colonized, approximately 10 days. Then, cold-shock the mycelium to start the fruiting process by refrigerating the bag for one day. The developing mushrooms will grow through the nail holes. Mist several times a day. Though the first fruiting will surpass the others, the bag should produce three to four “flushes,” or fruitings.


Optimal mushrooms Conditions

At best, mushroom growing is unpredictable. As much as possible, avoid mushrooms’ worst enemies: wind and sun. They prefer the dark or heavy shade and should never be placed where temperatures exceed 80 F. The spawn can survive in temperatures down to freezing. High humidity is required, but you must ensure good air circulation to discourage the growth of mold spores in the substrate, or growing medium.

Do mushrooms need sunlight?

Unlike plants, mushrooms do not contain chlorophyll andĀ do not require sunlight to grow. Whether mushrooms grow indoors or in the wild, they have certain light, water, heat and growing-medium requirements to thrive and produce their fruit.
How can I grow mushrooms without a kit?

The three easiest ways to grow mushrooms inside without using an out-of-the-box kit involveĀ plastic trash bags, a plastic container, or a laundry basket. You need a container of some sort that is extremely clean. You can use a bleach/water mixture to ensure that your container is clean.
