What is Milky Mushroom?

Milky Mushroom (Calocybe indica) is a tropical mushroom species developed and popularized in India. It produces large, thick, white fruit bodies with excellent shelf life compared to other summer mushrooms.

Key identity:

• Native to tropical climates

• Performs well at 30–38°C

• Grown indoors without cold rooms

This makes it a strategic summer crop when button mushrooms fail.

---

Why Milky Mushroom Farming Makes Sense (Strong View)

From a farming-business lens, Milky Mushroom ticks critical boxes:

• Summer-friendly (biggest advantage)

• Longer shelf life (2–3 days fresh)

• Thick stems = higher weight per mushroom

• Indoor controlled production

• Stable hotel & retail demand

This is capacity farming, not gamble farming.

Climate & Environmental Requirements

Milky Mushroom loves heat—but hates negligence.

Parameter	Ideal Range
Temperature	30–38°C
Humidity	70–85%
Light	Diffused / low light
Air	Fresh airflow (no stagnation)

 Below 25°C → slow growth
 Above 40°C → stress & deformation

---

Infrastructure Required (Simple but Disciplined)

You don’t need fancy labs.

Growing Room

• Brick room / shed / spare room

• Thatched or tin roof acceptable

• Whitewashed walls preferred

Essentials

• Ventilation windows or exhaust fan

• Water sprayer

• Thermometer + hygrometer

• Racks or hanging system

 Control > complexity.

---

Raw Materials Required

• Paddy straw or wheat straw

• Quality milky mushroom spawn

• Polythene grow bags (12×18 inch)

• Formalin or lime (for sanitation)

• Casing soil materials

• Clean water

Everything is locally available.

---

Substrate (Straw) Preparation

This step decides yield vs failure.

Straw Selection

• Dry, golden, mold-free straw

• Chop into 3–5 cm pieces

Soaking & Pasteurization

1. Soak straw in clean water for 8–10 hours

2. Drain excess water

3. Hot water treatment (65°C for 30 min)
   OR

4. Chemical treatment (formalin + lime)

Straw should be moist, not dripping.

---

Spawn Quality & Spawning Rate

Spawn = foundation capital.

Spawn Rules

• Fresh (not older than 10 days)

• Thick white mycelium

• No foul smell

Spawning Rate

• 4–5% of wet substrate weight

• ~100–120 g spawn per bag

More spawn = faster colonization = less contamination.

Bag Filling & Spawning Process

Step-by-Step

1. Take perforated polythene bag

2. Fill with treated straw

3. Mix spawn evenly (no layers)

4. Compress gently

5. Tie mouth tightly

Bag weight: 1.5–2 kg (wet)

Hang or place on racks.

---

Incubation Phase (10–12 Days)

• Temperature: 30–35°C

• No light needed

• No watering on bags

Within 10–12 days:

• Bag turns completely white

• Mycelium fully colonized

 If black/green patches appear → discard immediately.

---

Casing Soil: The Real Yield Lever

Milky Mushroom will not fruit without casing.

Standard Casing Mix

• Garden soil: 50%

• Sand: 25%

• Well-decomposed FYM: 25%

Casing Preparation

• Sterilize (sun drying or chemical)

• Moist but crumbly texture

Application

• Cut open bag top

• Apply 2–3 cm casing layer

• Light watering

This triggers fruiting.

---

Pinhead Formation & Crop Management

After casing:

• Pins appear in 7–10 days

• Maintain humidity with fine mist spray

• Ensure airflow (very important)

 Avoid direct water on pins
 Overwatering = bacterial rot

---

Harvesting Stage & Technique

Harvest when:

• Cap fully opened

• Mushroom is firm & white

Harvest Method

• Twist gently from base

• Clean casing soil

• Harvest daily for uniform size

One bag gives 2–3 flushes.

---

Expected Yield (Practical Numbers)

• Per bag: 600–900 g

• Biological efficiency: 60–70%

• Crop duration: 45–50 days

Yield improves with:

• Good casing

• Stable temperature

• Hygiene discipline

---

Cost of Milky Mushroom Farming (Small Unit)

Item	Approx Cost
Straw	Low
Spawn	Moderate
Bags & casing	Minimal
Room setup	One-time

 Capital-light, margin-heavy model.

Common Diseases & Prevention

Common Problems

• Green mold

• Bacterial blotch

• Fly infestation

Prevention SOP

• Clean room before every batch

• Use fresh spawn

• Remove infected bags immediately

• Maintain airflow

Chemicals are last resort, not first line.

---

Shelf Life & Storage

Big advantage here.

• Fresh shelf life: 2–3 days

• Store at 15–18°C

• Less shrinkage than paddy straw

This improves market flexibility.

---

Marketing Reality (No Illusions)

Best channels:

• Local vegetable markets

• Hotels & restaurants

• Retail vegetable shops

Sell fresh, clean, uniform mushrooms.
Consistency beats price wars.

---

Beginner Mistakes to Avoid

Hard truth:

•  Skipping casing sterilization

•  Poor ventilation

•  Overwatering

•  Using old spawn

•  Ignoring room hygiene

Milky Mushroom rewards process discipline, not shortcuts.

---

Scaling Strategy (Smart Way)

Once basics are locked:

• Increase bag count

• Batch production every 10–15 days

• Train helper labor

• Standardize SOPs

This becomes a repeatable indoor farming system.

---

Is Milky Mushroom Farming Worth It?

Yes—if treated as a system, not an experiment.

It is:

• Summer-proof

• Indoor-controllable

• Market-stable

• Scalable with discipline

Perfect for farmers who want predictable output, not seasonal anxiety.
