Frequently Asked Questions
When I buy mushrooms at the grocery store they sometimes have dirt on them, is that horse or cow manure?
Mushrooms grow on a layer of peat moss covering a thick layer of pasteurized compost. Usually the flecks of dirt are peat moss. Sometimes, there are bits of compost but the entire growing medium, whether it is compost or peat moss, is pasteurized! Most people do not know that there is an extensive pasteurization process that the growing medium goes through before inoculated with the mushroom spores.
Do mushrooms need to be in the dark to grow?
No, mushrooms get all their nutrition from the compost substrate. Unlike many plants, they do not need sunlight to make chlorophyll so we turn off the lights to save energy!
