  • Question
    How long does it take to grow edible mushrooms?
    Community Answer
    Oyster mushrooms take about three weeks for the first fruiting, but can take up to six weeks depending on the variety and growing conditions. After the first harvest, you'll usually get at least one more, spaced anywhere from three to fourteen days apart. Most other species take a bit longer to grow.
  • Question
    Can I place the tray in the sun for heat?
    Community Answer
    No, direct sun produces too much light and heat for mushrooms. Most strains do best at room temperature or slightly warmer. Some mushrooms grow faster at higher temperatures, but so do the bacteria and mold spores they are competing with, so it's a risky option.
  • Question
    How do I dry the mushrooms?
    Community Answer
    Get a box fan, two or more air conditioner filters (not fiberglass or plastic) and bungee cords. Clean and slice the mushrooms and lay them in the pleats of the air filter. Place the other filter on top, and keep alternating mushrooms and filters until you've used them all. Strap the filters to the front of the fan and run the fan until they are dry. Depending on temperature, humidity, and thickness of slices it can take anywhere from 24 hours to three days.

    The easiest way is to buy mushroom spawn online from a mushroom spawn laboratory. If you are having trouble finding a good source, ask a nearby mycological association for local advice.
  • Question
    Which mushrooms can humans eat?
    Community Answer
    There are several species we can eat, including the morel, horse mushroom and chanterelle. The best way to know is to check a mushroom guidebook, or ask someone who knows about collecting mushrooms for eating.
  • Question
    Is there a way to grow chanterelle?
    Community Answer
    I have not done this personally, but I would think you could dry them out and then shake out the spores, or make a print on paper and grow them in a petrie dish. You might get some spores online.
