Nowadays many farmers are shifting farming to other professions due to insufficient financial protection. Climatic change is a significant challenge for the farmer. More than 95% farmer uses the traditional farming technique in India. If we wanted to earn more profit from agriculture, we have to adopt modern farming techniques such as Greenhouse farming (polyhouse farming), hydroponic farming.

A Greenhouse is a framed structure covered with a transparent material and large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity.

Greenhouse Technology is the technique of providing favourable environment condition to the plants. Of all agricultural production activities, the greenhouse industry is worldwide the fastest growing sector. The greenhouse is goldmines that offer the most profitable business opportunities.

The use of the greenhouse is mainly for the production of seasonal and non- seasonal crops, for the production of high-quality flower, vegetable and the preparation of nursery prepared by tissue culture.

Greenhouses offer many advantages

  • The yield may be 10-12 times higher than that of outdoor cultivation depending upon the type of greenhouse, type of crop, environmental control facilities.
  • Reliability of crop increases under greenhouse cultivation.
  • Ideally suited for vegetables and flower crops.
  • Year round production of floricultural crops.
  • Off-season production of vegetable and fruit crops.
  • Disease-free and genetically superior transplants can be produced continuously.
  • Efficient utilization of chemicals, pesticides to control pest and diseases.
  • Water requirement of crops very limited and easy to control

There are different types of greenhouses available based on shape, construction, material, and ventilation. Each greenhouse has own advantage. Different types of the greenhouse are designed to according to match specific needs

Types of Greenhouse

Naturally Ventilated GreenHouse 

Portable, Long-Lasting, Adaptable
This type of greenhouse is based on natural ventilation and depending on the crops the temperature, humidity, and carbon dioxide gas can be maintained as per the requirement. In this Greenhouse, shade nets are used to prevent insect and bacterial access also for control inside temperature. This type of greenhouse used for the production of cut flower like Gerbera, Dutch rose, Carnation, Lily & Vegetable like Colour capsicum, Tomato, Cucumber, Exotic vegetables.

Fan & Pad Greenhouse

Many greenhouse operations rely on forced-air ventilation fans to move air into and out of the greenhouse. When inside temperatures exceed the desired level, a thermostat opens the shutters and starts the exhaust fan(s). As the fans exhaust the heated air, a slight vacuum is created that draws in cooler outside air through shutters. When the desired temperature has been reestablished, the thermostat shuts off the exhaust fans and closes the motorized shutters.


The principle of forced-air ventilation is to create air flow through the greenhouse. As air flows through the plants in the greenhouse, it absorbs heat and increases in both temperature and humidity before exiting the greenhouse through the exhaust fans. Fans either pull fresh air into a greenhouse or exhaust greenhouse air to the outside with replacement fresh air entering through vents or other openings.

Although there is no special preference, most commercial greenhouse operations use fans to exhaust air with replacement air pulled through vents from the outside. Forced-air ventilation includes exhaust fans on one end of the greenhouse and motorised louvered air inlets, or vents, at the opposite end for air exchange. Inlet shutters or window vents should be motorised.

Gravity-type inlet shutters have been used but are subject to wind forces during windy conditions and are not suitable for winter operation. In gutter-connected greenhouses, mechanical ventilation systems inlets and outlets can be installed in the side- or end walls. The fan louvers are installed interior to the fan blades so that the fan and housing are totally separated from the greenhouse environment when the fan is not operating. Particular attention to the location and the geometry of the inlet air device is crucial for effective cooling and uniform distribution.

Greenhouse Automation


To get your crops growing properly and with optimum efficiency, you need to have accurate control of your greenhouse. Process, climate, light & CO2, irrigation and operation can all be automated. They need to be effectively adjusted to one another, and preferably as accurately as possible.

The more accurately you can control your greenhouse, the more beneficial this is for your crops. To opt for IGCL, is to opt for a total solution, one that really does let you link and control all of the processes and systems in your business; allowing your crops to grow perfectly, just like your business.

The overall benefits of automating your grow operation are vast and plentiful. Regardless of how you’re looking to develop your growing enterprise, automation offers universal benefits that allow you to achieve your goals – and then some.

  • Decrease your labor costs
    By reducing the amount of work that needs to be done manually, you can decrease your labor costs or allow you to free up workers to focus on other areas of importance. Perfect if you are looking to expand your business or introduce new skills to your workers.
  • Be accurate
    Know exactly what’s happening in your greenhouse and make data driven decisions based on facts and not assumptions. The technology and equipment exist to benefit you as the grower!
  • Increase quality and yield
    If you don’t measure you can’t improve. Automation will give you the knowledge to increase quality and yield, learn from previous crop cycles, and give you better return on investment (ROI).
