Grow Lion s Mane Mushrooms Indoors – All You Need to Know

What Is a Lions Mane Mushroom?

Lion s mane are scientifically called hericium erinaceus. They are a species of fungi, most commonly found on dead logs in the wild throughout North America.

Also known as bearded hedgehog mushrooms, bearded toothed mushrooms, or even pom pom mushrooms, lion’s mane grow in the fall season.

These mushrooms start out as tiny, white spines that elongate and into a large snowball-like formation as the mushroom grows. If the spines get damaged or the mushroom gets old, they turn brown from white.

Lions mane mushrooms have more to offer besides their appearance. They have a delectable, crab-meat like flavor. Most mushrooms connoisseurs think that the taste is to that of a lobster.

Types of Spawn and Substrate Needed for Growing Lion s Mane

Mushroom spawn or mycelium is the substance that is grown on mushroom substrate. For lion s mushrooms, mycelium made of grains, rye grain in particular, are ideal.

Sawdust spawn is also used commonly since it helps the h erinaceus mushrooms grow faster.

The mycelium of lion’s mane is thin and wispy, much like the white spines and requires careful inspection throughout the mushroom growing process.

Lion mushroom spawn is best grown on sawdust from hardwood. To grow lion s mane, you will have to supplement it with 10 to 20 percent wheat bran. Full colonization is very much possible with lion’s mane shrooms.

How to Grow Lion s Mane Mushrooms – A Guide

In this section, we will shed light on how to grow lion s mane shrooms inside your home. The process is fairly simple. There are 2 ways to grow lion’s mushrooms at home: using logs and using hardwood sawdust substrate.

Let’s take a look at each of these methods in detail:

Growing Lion s Mane on Logs

What You Will Need:

  • Hardwood logs, preferably maple, oak or birch. For long-term flushes, choose elm, oak chestnut or black walnut. For short-term growth, you can also use poplar, willow and tulip.
  • Spawn plugs
  • Sealing wax
  • Hammer
  • Drill
  • Double boiler
  • Paintbrush
  • Thermometer

The Process:

Place your log on a dry, raised surface with ample sunlight for about 2 months. This will dry them out. Your log must only contain 40% moisture.

When your logs have dried out, it’s time to inoculate them with spawn. The best time for inoculation is during spring.

Using the drill, drill a row of 1-inch deep holes into each log. Mark spots with a chalk so they are equally spaced to get the most out of each log. Each hole must be at least 8 inches apart.

Melt wax in the boiler and use the thermometer to measure the temperature. It should stay below 211 degrees Fahrenheit.

After you have drilled the holes, place spawn plugs into each hole. Use a hammer to gently push the spawn into the hole.

Use a paintbrush to place the melted wax over the spawn plug and hole. Once all holes in a log have been filled and sealed with wax, soak the log for up to 24 hours.

After 24 hours, place your logs in a shaded, moist area with adequate air circulation. You can stack them up as well.

White fuzz on the ends of logs will tell you that the mushrooms are growing. Cut the snowball mushroom pinhead off with a sharp knife to harvest it. Be careful! You don’t want to damage the spines in the process.

Enjoy immediately or refrigerate them for up to 2 weeks.

It can take up to 6 months for lion’s mane to grow on logs and produce the first flush. However, these logs have the ability to keep providing multiple flushes for up to 6 years.

Growing Lion s Mane on Sawdust Spawn

What You Will Need:

  • 5 cups of wooden fuel pellets or sawdust in a bag
  • 1 cup of wheat bran
  • 1 cup of molasses
  • 6 cups of warm water
  • Mushroom spawn

The Process:

Combine the sawdust, pellets, wheat bran and molasses together. Add water gradually till the mixture forms clumps. Some water should drip out if you squeeze the mixture.

Add mixture to a grow bag. Fold and seal the bag. Sterilize the bag in a canning rack and weigh the bag down (video). Leave the bag for 2.5 to 3 hours to kill bacteria then cool it.

Add mushroom spawn to the grow bag. You will need about 2 pounds of spawn for every 10 pounds of mixture.

Place the bag in a dark, warm and moist area. In a few weeks, you will see your bag would have turned brown and mycelium will be growing over it.

Next, puncture the bag with holes about 1/3rd of an inch to encourage fruit growth. Ensure it gets indirect sunlight and sufficient air.

In 1 to 2 weeks, you will witness mushroom pins emerging from the holes.

Keep checking the grow bag after every few days for fungus growth, mold and dry spots.

Once grown, cut the spiny mushroom heads from grow bag using a sharp knife. Enjoy immediately or refrigerate them for up to 2 weeks.
