How to Grow Mushrooms. Mushrooms grow from spores, not seeds. You can grow this curious food indoors or
out with a little preparation and the right supplies. You will need Mushroom spores Growing area
Nutrient-rich soil Growing bed Substrate Hot water or pressure cooker Temperature and humidity
control Basement or crawl space (optional) and humidity tent (optional). Step 1. Pick the right culture spores for your skill
level — oyster and button mushrooms are the easiest to grow, while shiitake and morel
mushrooms can be difficult. Search online for the different types of spores
and their difficulties. Step 2. Choose a growing area that is cool, dark,
and free from pests that may eat or contaminate your mushroom farm. The best growing areas are basements or crawl
spaces. Step 3. Spread a dark, nutrient-rich soil evenly over
a level growing bed to a thickness of about 2 inches. Step 4. Sterilize your substrate by soaking it in
hot water or putting it in a pressure cooker to kill undesirable fungi and bacteria that
can ruin your mushroom batch. Different species of mushrooms thrive on different
substrates, like straw, compost, wood chips, sawdust, newspaper, or cardboard. Step 5. Apply the appropriate substrate or growing
medium over your soil to feed your hungry mushroom spores. Step 6. Implant or inoculate the substrate with your
mushroom spores and fine tune the temperature and humidity levels based on the species. Some varieties require higher humidity than
others. You may need a humidity tent to increase humidity
levels. Step 7. Look for sprouting, or “pinning,” after about
three weeks. The mushrooms will be ready for harvesting
in as little as one month. Did you know A fungus colony discovered in
Northern Oregon may be the largest single organism in the world, covering over 2,300
square acres — that’s about 1,665 football fields.
