ABOUT THE GREENHOUSE SYSTEM

Greenhouse for Mushroom Growing

This project is a modern greenhouse system specially designed for Button Mushroom cultivation.

The entire setup is created to maintain controlled temperature, humidity, airflow, and hygiene, which are essential for consistent mushroom production.

Unlike traditional open or temporary structures, this greenhouse is a fully enclosed, insulated growing environment that allows year-round production with better yield, quality, and control.

Purpose of This Greenhouse System

The greenhouse system is designed to:

  • Maintain ideal growing conditions for Button Mushroom
  • Support small, medium, and large-scale projects
  • Reduce dependency on external weather conditions
  • Improve production consistency and hygiene
  • Allow efficient use of equipment and materials


This system can be customized according to:

  • Project size
  • Daily or monthly production capacity
  • Available space
  • Client requirements

Controlled Growing Environment

This mushroom growing setup is designed as a fully enclosed and controlled growing environment, where key conditions required for Button Mushroom cultivation are maintained throughout the production cycle.

  • Fully controlled internal environment
  • Insulated walls and roof for temperature stability
  • Controlled air circulation and CO₂ management
  • Controlled humidity and moisture levels
  • Hygienic and enclosed growing space


All growing conditions are maintained through controlled systems, independent of external climate variations.

System Scope

The greenhouse system covers the complete mushroom

production process, including:

  • Compost preparation infrastructure
  • Controlled growing rooms
  • Temperature and humidity control systems
  • Air circulation and filtration
  • Internal layout for mushroom bags and racks
  • Harvesting and basic handling support


This makes it a complete greenhouse solution for mushroom growing, not just a room or storage space.

Stage -1

OVERALL PROCESS FLOW

The Greenhouse for Mushroom Growing system follows a structured process where each stage supports the next. All activities are carried out within a controlled and hygienic environment to ensure stable production and consistent quality. This page provides a high-level overview of the complete process.

Compost Preparation

Step 1 – Compost Preparation

Preparation of mushroom compost using selected raw materials

Compost is conditioned to support healthy mushroom growth

Compost handling is carried out using manual or mechanical systems

This stage prepares the growing medium required for Button Mushroom cultivation.

Bag Filling and Spawning

Step 2 – Bag Filling and Spawning

Prepared compost is filled into 10 kg mushroom growing bags

Mushroom spawn is mixed with compost before room placement

Bags are ready for placement inside the greenhouse growing room

This step ensures uniform distribution of spawn within the compost.

Compost Preparation

Controlled Growing Room

Step 3 – Controlled Growing Room

Mushroom bags are placed on racks inside the insulated greenhouse room

Environmental conditions are maintained using refrigeration, airflow, and humidity systems

All cultivation stages take place inside the same controlled room

This allows efficient use of space and equipment.

Environmental Management

Step 4 – Environmental Management

Temperature, humidity, and CO₂ levels are monitored and adjusted

Fresh air circulation and filtration are maintained

Systems can be operated manually or through automation

This ensures stable conditions throughout the production cycle.

Harvesting and Basic Handling

Step 5 – Harvesting and Basic Handling

Button mushrooms are harvested manually at maturity

Harvesting is done in clean and controlled conditions

Mushrooms are prepared for packing after harvest

Stage -2

COMPOST PREPARATION SYSTEM

Compost preparation is the most critical stage in Button Mushroom cultivation.

The compost acts as the growing medium and food source for mushrooms. If compost quality is poor, mushroom yield and quality are directly affected.

For this reason, the Greenhouse for Mushroom Growing system includes a dedicated compost preparation infrastructure, supported by specific machines and laboratory facilities.

Mixing Yard (Initial Compost Preparation Area)

The compost preparation process starts in a mixing yard.

Why a mixing yard is required:

  • To combine all raw compost materials in correct proportion
  • To ensure uniform moisture and texture before compost conditioning
  • To prepare a consistent mixture before transferring to bunkers


Raw materials handled in the mixing yard:

  • Cocopeat – helps retain moisture and improves compost structure
  • Straw / Bhusa (wheat straw) – main organic base for compost
  • Chicken manure – provides nitrogen required for compost activity
  • Urea – added in controlled quantity to support compost conditioning
  • Gypsum – improves compost texture and prevents stickiness


How mixing is carried out:

  • Manual mixing using human labor
  • Mechanical mixing using JCB or loader for larger quantities
  • Compost mixing machines to improve speed and uniformity.


Without proper mixing, compost quality becomes uneven, which affects mushroom growth later.

Compose Preparation

Bunker System (Open Aerated Compost Conditioning Stage) After mixing, the compost is transferred into bunkers.

Why bunkers are used:

  • To allow compost to undergo controlled biological activity
  • To prevent compost from overheating
  • To prepare compost gradually before tunnel conditioning. 

Bunker system characteristics:

  • Open structure for easy loading and unloading
  • Designed for bulk compost holding
  • Compost remains in bunkers for approximately 7 days
  • Multiple bunkers allow rotation of compost batches.


Why aeration is necessary in bunkers:

  • Compost generates heat naturally
  • Without air supply, compost can get damaged
  • Proper aeration keeps compost active but stable

Machines and materials used for aeration:

  • Industrial air blowers (5 HP / 7.5 HP / 10 HP)
  • Push fresh air into the compost mass
  • Spigots (air diffusers)
  • Distribute air evenly below compost
  • Perforated air pipes / ducting
  • Carry air from blower to spigots
