Choosing the Right Substrate for Milky Mushroom Cultivation

One of the most critical factors affecting the success of milky mushroom cultivation is the

choice of substrate — the organic material on which mushrooms grow. Milky mushrooms

are saprophytic fungi, meaning they feed on decomposing organic matter.

Common Substrates Used

Paddy Straw: The most popular and cost-effective substrate, widely available in

1.

rice-growing regions.

Sugarcane Bagasse: Offers good yield but requires proper pasteurization.

2.

Wheat Straw: Another excellent choice for substrate, especially in temperate

3.

climates.

Corncobs and Sawdust: Often mixed with other substrates to enhance nutrient

4.

content.

Choosing a substrate depends on local availability and environmental factors. Paddy straw

remains the preferred material for large-scale milky mushroom cultivation due to its

abundance and nutrient profile.

Preparing the Substrate: The Key to Healthy Growth

Substrate preparation involves several steps that ensure a contamination-free and

nutrient-rich base for the mushroom spawn to colonize.

Step 1: Collection and Cleaning

Collect the substrate material and remove any dust, stones, or other foreign particles.

Clean the straw or other substrates thoroughly.

Step 2: Chopping

Cut the substrate into smaller pieces, typically 2-3 inches in length, to create a more

manageable and aerated medium.

Step 3: Moisture Adjustment

Soak the substrate in clean water for 12-16 hours to achieve an optimum moisture

content of approximately 65-70%. Proper moisture is crucial — too dry, and the mycelium

won’t grow well; too wet, and the substrate may become anaerobic, inviting

contamination.

Step 4: Pasteurization or Sterilization

To kill unwanted pathogens, pasteurize the substrate by soaking it in hot water (around

60-70°C) for 6-8 hours. Alternatively, steam sterilization can be done for enhanced results,

especially in commercial setups.

Spawn Selection and Inoculation

Spawn is the mushroom seed, consisting of mycelium cultured on a carrier medium like

grains.

Types of Spawn

Grain spawn: Most commonly used due to ease of handling.

Sawdust spawn: Sometimes preferred for specific substrates.

Selecting high-quality, disease-free spawn from reputable suppliers is vital for successful

milky mushroom cultivation.

Inoculation Process

Once the substrate has cooled after pasteurization, mix it thoroughly with the spawn in a

clean environment to avoid contamination. The recommended spawn rate for milky

mushroom cultivation is typically 5-10% of the wet substrate weight.

Creating Optimal Growing Conditions

Milky mushrooms prefer warm and humid environments, with temperature and humidity

playing critical roles in their development.

Temperature

Spawn Run: 28-32°C is ideal for rapid mycelial growth.

Fruiting: Slightly cooler temperatures around 25-28°C encourage mushroom

formation.

Humidity

Maintain relative humidity between 85-90% during fruiting to prevent the mushrooms

from drying out.

Ventilation and Light

Good air circulation is necessary to prevent carbon dioxide buildup, which can hinder

fruiting. While milky mushrooms do not require intense light, indirect natural light or low-

intensity artificial light helps in proper development.

Harvesting and Post-Harvest Handling

Proper timing and technique during harvesting can significantly affect the quality and

shelf life of milky mushrooms.

When to Harvest

Harvest mushrooms when the caps are fully expanded but before the edges begin to curl

upwards. This stage ensures the best texture and flavor.

Harvesting Tips

Gently twist and pull the mushrooms from the substrate to avoid damaging the mycelium,

which can produce subsequent flushes.

Post-Harvest Storage

Store milky mushrooms in breathable packaging at temperatures around 4-6°C to extend

freshness. They typically have a shelf life of 3-5 days under refrigeration.

Common Challenges and Tips for Successful Milky Mushroom

Cultivation

Like any agricultural venture, milky mushroom cultivation comes with its set of

challenges. Contamination by molds, bacteria, or pests can affect yield and quality.
