What Makes Oyster Mushrooms so Easy to Grow at Home?

Oyster mushrooms are the easiest mushrooms to grow since they love all different types of growing mediums including coffee grounds, straw, and hardwood sawdust and shavings.

They are also quick to grow and can tolerate a wide range of bacterial species, including blue or green mold.

When your mushroom kit arrives in the mail you slice a hole in the plastic bag and place it in your home where it can receive fresh oxygen, low-level light, and maintain average indoor temperatures. The kit comes with a little sprayer that you will use to keep the growing material moist by spraying it a few times a day. Oyster mushrooms love a humid environment!

This signals to the mycelium that it’s time to start producing mushrooms and small pins begin to emerge. Oyster mushroom pins will begin to emerge from holes in the plastic grow bag. These small pins, which are fed by water and nutrients from the mycelium, rapidly develop into full-size mushrooms in just 5-7 days. Oysters mushrooms can be ready to harvest just 7 days after starting to grow out of the plastic bag! A mushroom crop can be harvested three times before the mycelium runs out.

Optimal Conditions for Growing Oyster Mushrooms Indoors

Maintaining a Healthy Mushroom Environment

Fungi, specifically Oyster Mushrooms, have unique environmental needs compared to the houseplants you may be used to. These are the best conditions for your mushroom to thrive. The important thing is to have the optimal conditions to grow mushrooms indoors:

  • Low light. Indirect light or shade is perfect for growing Oyster Mushrooms. Unlike plants, these fungi doesn’t need sunlight to develop. Its internal fruitbodies will grow just fine in the shade.
  • Humidity. Mushrooms need moisture and love high humidity. Most fungi cannot develop in dry conditions, and the Oyster Mushroom in particular craves humidity. Spraying your growth medium once or twice a day with a water mister will help promote healthy growth.
  • Air flow. Wild Oyster Mushrooms grow in open-air, breezy environments. Access to plenty of oxygen and good air circulation will ensure your mushrooms grow to their full potential. Whatever container you use for your grow kit, make sure there are some holes incorporated to encourage air flow.
  • Moderate room temperatures. 50-86 degrees Fahrenheit is this mushroom’s preferred temperature range. As long as you stay within this, the Oyster Mushroom isn’t too particular. Average room temperature is A-okay for growing your fungi!

Why Grow Your Own Mushrooms

Growing your own mushrooms at home is super fun! No matter how much experience you have with indoor plants, making the leap into growing fungi is an exciting new adventure. Mushrooms have very different growing environments and needs than the typical houseplant. Exploring the different ways to cultivate fungi will quickly become your new hobby. Oyster Mushrooms also make a delicious cooking ingredient or snack. They’re jam-packed with fiber, antioxidants, and plenty of vitamins and minerals.

How to Grow Oyster Mushrooms

I love using these North Spore grow kits to cultivate my own mushrooms. This small, family-owned Maine business provides kits with a how-to guide, substrate with a fresh mushroom mycelium, and a spray bottle. However, if you have your own spore starters and want to build a home for it, here’s how. These basic steps will help ensure maximum growth of your Oyster Mushrooms.

  • Prepare a large container. Five-gallon buckets, large plastic bags, or properly treated cardboard can all be used to house your mycelium. If using a sealable container, make sure to add some air holes for proper oxygen flow.
  • Gather up a substrate base. This material will be used to keep your mycelium fed. There are lots of different substrates you can use. Clean straw is the most common for Oyster Mushrooms, but you can also use sawdust, cardboard, coffee grounds, or other clean composts.
  • Mix in your spore spawn. Spread out your substrate on a clean surface and sprinkle your spore starter over the material. Give it a good mix to infuse the two.
  • Place your substrate into the container. When the spawn and substrate are mixed well, place the combined materials into your prepared container. Move this container into its growing habitat.

Ready, set, grow!

The Best Time to Grow Oyster Mushrooms

In the wild, season matters when growing Oyster Mushrooms. New mushrooms will begin to form once temperatures reach the 50-60 Fahrenheit degree range. What time of year this is depends on your region. When using a grow kit or otherwise growing indoors, you can control the climate of your space to grow year-round.

Harvesting Oyster Mushrooms

Your Oyster Mushrooms are ready to harvest when the mushroom caps begin to flatten or curve upward. Caps that are shedding a dust also are ready to harvest. Carefully cut off clusters with a knife. To harvest individual caps, grasp it gently in your hand and twist until it is free. Overly large mushrooms may be overgrown, so harvest early once the edges begin to lift.

3 Quick Tips for Growing Your Oyster Mushrooms

  • Keep mushroom kit away from drafts
  • Control humidity to avoid mushroom shriveling or moldy growth
  • Harvest mushrooms when they’re ready, never rush them or pull mushroom blocks too early
