Discover 10 common mistakes beginners make in Cordyceps farming

Cordyceps farming is having its moment. From small farmers to city-based entrepreneurs, everyone’s hearing stories of people making lakhs from growing this unique “medicinal mushroom.” 

And why not? Cordyceps militaris is in demand, especially in the health and wellness space, for its energy-boosting and immunity-enhancing properties.

But here’s the truth no one tells you right away: Cordyceps isn’t as easy to grow as other mushrooms like oyster or button mushrooms. 

It’s sensitive, demanding, and requires scientific precision. Many beginners dive into this farming model thinking it’s a shortcut to quick profits—and end up losing their money.

1. Starting Without Proper Training

Let’s be honest—Cordyceps cultivation isn’t something you can pick up from a couple of YouTube videos. It involves understanding fungal biology, sterilization techniques, contamination control, and more. A major mistake beginners make is skipping formal training altogether.

Solution:
Before investing in equipment, enroll in a reliable workshop or training program. Learn hands-on from professionals who know the process inside out. Online classes are useful too, but physical, practical experience makes a big difference in this field.

2. Using Cheap or Wrong Substrate

Cordyceps militaris grows on a synthetic medium, often based on grains like rice or wheat, but it's not as simple as tossing rice into jars. Many beginners try to cut costs using cheap grains or fail to add essential nutrients.

The result? Poor fungal growth and disappointing yields.

Solution:
Use high-quality, polished grains free of chemicals. Follow tested substrate recipes that include additives like yeast extract, vitamins, and minerals for better yields. Don’t compromise here—the substrate feeds your Cordyceps.

3. Not Taking Sterilization Seriously

Contamination is the silent killer in Cordyceps farming. Mold and bacteria love invading your substrate. Many new growers either skip pressure sterilization or use unclean tools and working spaces. Opening jars without precautions also introduces contaminants.

Solution:

• Always sterilize substrates in a pressure cooker or autoclave for 1.5 to 2 hours.

• Use 70% alcohol to disinfect tools and hands.

• Perform inoculation inside a clean environment—ideally under a laminar airflow cabinet or in a sanitized room.

4. Setting Up in the Wrong Environment

Cordyceps doesn’t grow well in open-air setups or rooms with fluctuating temperatures. Beginners often think a spare room is enough. Unfortunately, temperature and humidity play a huge role in its growth.

Solution:

• Maintain temperatures of 20-22°C for mycelium growth and 18-20°C during fruiting.

• Control humidity (around 65% for growth and up to 80% for fruiting).

• Use temperature controllers, humidifiers, and appropriate lighting (around 500 lux) to simulate ideal conditions.

5. Using Poor-Quality Spawn or Mother Culture

Your Cordyceps batch is only as good as your spawn. Beginners sometimes buy spawn from unreliable sources or reuse old spawn, leading to weak mycelium and low yields.

Solution:

• Purchase mother culture or spawn only from trusted, lab-certified sources.

• Keep spawn refrigerated until use and avoid long storage times.

• Always check for signs of contamination before inoculating.

6. Incorrect or Delayed Inoculation

Once your substrate is sterilized, you can't afford to waste time. Delaying inoculation allows contaminants to settle in. Similarly, many beginners inoculate at wrong temperatures or in unclean environments.

Solution:

• Cool down your sterilized jars and inoculate immediately in a sterile setup.

• Avoid unnecessary handling and opening of jars after inoculation.

7. Ignoring Batch Monitoring

One common rookie mistake is “set it and forget it.” Cordyceps isn’t something you can leave unattended. Beginners often fail to check for contamination, drying out, or poor mycelium growth until it’s too late.

Solution:

• Inspect your jars daily, especially during the mycelium and fruiting stages.

• Watch for any discoloration, strange smells, or unusual textures in the substrate.

8. Poor Timing of Harvest

Harvesting Cordyceps isn’t about waiting as long as possible. Many new farmers harvest too early, missing out on potential size and potency. Others wait too long, leading to dry, over-mature fruiting bodies.

Solution:

• Ideally, harvest when fruiting bodies reach 6-8 cm, are bright orange, and before they start releasing spores (you’ll notice a powdery surface).

• Handle gently to avoid damaging the delicate mushrooms.

9. Skipping Quality Testing

Since Cordyceps is a medicinal product, selling untested harvests is risky—not just for customers but for your brand reputation. Beginners often ignore testing altogether, not realizing buyers expect proof of quality.

Solution:

• Test your harvest for Cordycepin levels (the main bioactive compound).

• Check for heavy metals and microbial load via a certified lab.

• Maintain batch-wise lab reports, especially when selling to companies or exporters.

10. No Marketing or Sales Strategy

You’ve successfully grown Cordyceps... now what? Many new farmers are so focused on cultivation that they forget about sales. Without a clear marketing or sales strategy, you’ll struggle to find buyers after harvest.

Solution:

• Start marketing while your batch is growing.

• Build a professional online presence through social media or a simple website.

• Network with supplement brands, herbal medicine shops, and B2B buyers.

• Consider selling dried fruiting bodies directly to end consumers too.

If there’s one thing Cordyceps farming teaches you, it’s patience. This isn’t a side hustle you can manage casually—it requires attention to detail and a scientific approach.

That said, the rewards are real. Once you master the process, Cordyceps farming can offer excellent returns with relatively low recurring costs.

To sum up:

• Learn first, invest later.

• Treat your farm like a lab, not a kitchen.

• Stay consistent with your process.

• Always be ready to learn and adapt.

Remember, it’s okay to make mistakes—that’s how every grower learns. But knowing what to watch out for can save you from expensive errors.

So, whether you’re just starting or trying to improve, keep these lessons in mind—and soon, you’ll be on your way to a successful Cordyceps harvest.
