Cordyceps militaris, often called the caterpillar fungus, is one of the most intriguing and valuable medicinal mushrooms in the world. While the wild species Cordyceps sinensis is rare and grows parasitically on insect larvae in the Himalayas, Cordyceps militaris offers a cultivated alternative that contains similar bioactive compounds, including cordycepin and adenosine, which are associated with energy, stamina, immune support, and anti-aging effects. This Guide to Growing Cordyceps militaris Mushroom is a most for those wanting to dive deeper into this fascinating mushroom.
This guide will walk you through the complete process of growing Cordyceps militaris mushroom at home or in a small commercial setup, including substrate selection, environmental conditions, harvesting, and where to get high-quality spawn and cultures—including from The Spore Depot.
What Is Cordyceps militaris Mushroom (Caterpillar Fungus)?
Cordyceps militaris is a parasitic fungus that naturally infects insects but can be successfully cultivated on plant-based media. It’s bright orange, finger-like fruiting bodies make it easily recognizable. Unlike Cordyceps sinensis, which relies on insect larvae, Cordyceps militaris can grow on artificial substrates such as grains or silkworm pupae, making it an accessible and ethical option for mushroom growers.
Why Grow Cordyceps militaris Mushrooms?
- ✅ High medicinal value – boosts energy, endurance, immunity, and cognitive function
- ✅ Ethical and vegan cultivation
- ✅ Can be grown indoors with relatively low tech
- ✅ High market value in supplement and health food industries
The Ultimate Guide to Growing Cordyceps militaris Mushroom
Ideal Environmental Conditions
- Temperature: 60–70°F (15–21°C)
- Humidity: 70–90%
- Light: 12–16 hours of indirect or diffuse light daily (around 1000–2000 lux)
- CO₂: Needs fresh air exchange to avoid elongation of fruiting bodies
- Sterility: Cordyceps is highly sensitive to contamination; clean lab practices are essential

Choosing a Substrate for Cordyceps militaris
Growing Cordyceps militaris mushroom successfully depends heavily on the substrate used. It’s unique among mushrooms in that it prefers insect-based nutrients, though it can be grown on vegan alternatives. Guide to Growing Cordyceps militaris Mushroom!
Common substrates for Cordyceps militaris:
- Brown rice (most common and beginner-friendly)
- Silkworm pupae (traditional, but not vegan)
- White rice + nutritional supplements (yeast extract, soy powder, vitamins)
- Custom formulas like the VITA mix (brown rice, soy peptone, dextrose, and trace minerals)
🧪 pH balance is important: Ideal pH is around 5.5–6.0.
Step-by-Step Guide to Growing Cordyceps militaris Mushroom
Step 1: Preparing the Substrate
📦 Use small glass or plastic jars (100–250 ml) for each grow container.
Basic brown rice formula:
- 20g brown rice
- 0.5–1g yeast extract or soy peptone
- 0.5g glucose or dextrose
- 40ml distilled water
Process:
- Mix ingredients thoroughly in jars
- Cover with breathable lid or foil and secure with rubber bands
- Sterilize at 15 PSI for 90 minutes in a pressure cooker
Allow jars to cool to room temperature before inoculation.
🛒 You can purchase ready-to-inoculate substrates or Cordyceps-specific media at The Spore Depot
Step 2: Inoculating with Cordyceps militaris Spawn
Inoculate each jar with Cordyceps militaris liquid culture under sterile conditions (such as a still air box or laminar flow hood).
You’ll need:
- Sterile syringe with liquid culture
- Alcohol wipes or flame for sterilizing
- Nitrile gloves and mask (to prevent contamination)
📍 Inject 1–2 ml of liquid culture into each jar. Swirl gently to spread.

Step 3: Incubation Phase, Guide to Growing Cordyceps militaris Mushroom
Cordyceps mycelium will take 10–20 days to fully colonize the rice substrate.
📍 Incubation conditions:
- Temperature: 68–72°F (20–22°C)
- Light: Dark or low light
- Humidity: Not required (jars are sealed)
- Observation: Mycelium should appear white to yellowish-orange
Check for signs of contamination (green mold, wet spots) and discard contaminated jars immediately.
Step 4: Inducing Fruiting of Cordyceps militaris
Once colonized, jars should be transferred to fruiting conditions.
📍 Fruiting chamber conditions:
- Light: 12–16 hours of light per day at 1000–2000 lux (e.g., LED grow lights)
- Temperature: 60–65°F (16–18°C)
- Humidity: 80–90%
- Fresh air exchange: At least 3–5 times daily to prevent long, stringy growth
Leave jar lids loose or use breathable filter lids. Fruiting bodies will begin to emerge in 5–10 days.
Step 5: Maturation and Harvesting
Growing Cordyceps militaris mushroom takes about 45–60 days from inoculation to harvest.
✔ Mushrooms are ready when:
- Fruiting bodies are 1.5–2 inches tall
- Tips begin to darken or curve slightly
- They feel firm to the touch
Use clean scissors or tweezers to harvest. Handle gently to avoid bruising. Guide to Growing Cordyceps militaris Mushroom!
Step 6: Drying and Storing Cordyceps militaris
💨 Drying method:
- Use a dehydrator at 110°F (43°C) until mushrooms are fully dry
- Store in airtight glass containers away from light and heat
Properly dried Cordyceps can last for over a year and can be ground into powder, made into tea, or used in tinctures and capsules.
