Gourmet mushrooms fetch high prices at grocery stores. Cultivate mushroom varieties at home and save money. Many fungi species grow well in Florida's hot and humid climate. Wild varieties such as the Florida Oyster are often sought out and are beginning to be cultivated by home growers. Research the ideal growing conditions of your mushrooms before cultivation begins.
Order sawdust inoculated with the mushroom spores of your choice. Strains such as the Almond Mushroom and the Paddy Straw Mushroom grow well in Florida's climate and can be found online.
Place cardboard in water and allow to soak for at least one hour. Each piece of cardboard should be 2 by 3 feet long to provide enough room for growth.
Peel apart wet cardboard until the ribbed side is fully exposed.
Coat the ribbed side of the cardboard in the inoculated sawdust. This is the food the mushrooms will grow on.
Roll the piece of cardboard into a burrito shape with the sawdust coating inside. Hold the ends together with paper clips, staples or tape.
Place in a cool, dark location. Shady garden areas or ventilated porches and basements work well as mushroom grow houses.
Mist the cardboard with fresh water daily to elevate humidity and encourage the growth of spores.
Give the mushrooms time to colonize the cardboard. Mushrooms can take anywhere from several weeks to several months to fully mature. Most are ready to be harvested when the cap has fully opened.
