Mushrooms have been popular in home gardening in China for the past 1,000 years. More recently, the trend has taken off in North America and is considered a fine culinary occupation. The easiest way to grow mushrooms is with a mushroom kit. With the right kit, you can grow oyster, shitake and button mushrooms right on your dining room table. Mushrooms kits come with all materials needed, including spores. Growing mushrooms at home is a great way to eat fresh food without paying high prices.
Sterilize the substrate by dunking it in boiling water for 25 minutes. Allow to simmer for an additional 35 minutes before cooling for three hours. Substrate usually comes in a porous bag (such as burlap) and should have the air bubbles removed by pressing on it with a stick or spoon.
Add spawns to the substrate. Pour substrate into a clear plastic bag and crumble the spawn onto the substrate. Mix well.
Place spawned substrate in a warm, dark place with temperatures between 26 and 28 degrees Celsius (78 to 82 degrees Fahrenheit). While still in the bag, level off the substrate by placing it in a flat tray. After approximately 12 days, the substrate should be covered with white mycelium.
Sterilize the casing soil by heating it in a microwave for two minutes and then allowing to cool to room temperature.
Mix casing soil with water and let sit overnight.
Sprinkle casing soil over substrate and return to cool, dark place. Let sit in 26 to 28 degrees Celsius for five days.
After five days, place your casing soil in direct light for 12 hours a day. Air temperature should be kept between 25 and 27 degrees Celsius (77 to 80 derees Fahrenheit) . Mushroom caps should start growing within a few days. Once the caps fully open, they are ready to be picked.
