The easiest way to grow mushrooms at home is to buy a mushroom-growing kit. These kits can be purchased from a variety of sources, including ads in magazines and newspapers as well as online. While it is possible to grow your own mushrooms without the use of a kit, the steps involved are complex and time-consuming. In most cases all that is required to begin growing mushrooms from a kit is to moisten the growing medium and place it in a dark location.
Decide what type of mushroom (or mushrooms) you wish to grow at home and then purchase an appropriate mushroom growing kit. Kits are available to grow a wide variety of mushrooms.
Read and follow the instructions provided with the kit you purchase. Some kits require that you mix the growing medium and/or that you spread the mushroom spores (seeds) onto the surface of the growing medium. Some kits come with the spores already in place.
Add water to the kit. Use only distilled water unless the manufacturer suggests otherwise. Fill a spray bottle with room-temperature (never cold) distilled water and thoroughly dampen the surface of the growing medium, but do not make it soggy.
Place your dampened growing kit in a dark and moist location if you have one. If not, place it in a dark location, such as in a closet. Put it where temperatures are as close as possible to those recommended for your particular kit. In most cases a temperature of 55 to 70 degrees F is perfect.
Check your kit on a daily basis and spray the surface with distilled water as needed to keep the growing surface damp but not soggy.
Watch for mushrooms to begin growing within seven to 10 days. Harvest your mushrooms approximately 14 to 21 days later.
