The humidity and sun light is directly proportional to the life process of the plant and it is known as photosynthesis process. The influence of humidity and sun light stimulate the leave and branches for the correct and balanced distribution of carbon dioxide in the plant and boosting the healthy growth of the plant.

The greenhouse technology has developed and adopted by the world due to its merits to cultivate the crops through out the year with out the consideration of natural climate changes. The factors are to be taken care of by the greenhouse cultivator is to keep the inside climate friendly to the plants growing in the greenhouse. The friendly atmosphere to the plants means the right level of temperature, humidity, required light rays, moisture level for the roots and sufficient air circulation.

The greenhouse environment must be evergreen for every season through out the year. The temperature is the main factor to regulate the humidity and moisture and it is most important to maintain the temperature in required level forever. The chamber environment must be protected to maintaining the energy balance in the greenhouse, as it is very essential for the growth of the plants.

The heat and humidity parameters are having influence in the photo tropical and photosynthetic process of the plants. The growth of various plants like vegetables, exotic fruits, flowering plants, orchids, and others in the greenhouse is in need of their own warming and cooling depending up on the climate changes. The most important aspects of a greenhouse are the proper Lighting, balanced humidification, and cooling systems.

Which generate different effects in the growth of the plant. Evaporative coolers can help the greenhouse to achieve the above conditions by its quality to sustaining the humidity and temperature. The unbalanced state of humidity may not be controlled to the perfect required value; even then, all the plants got their own capabilities to adjust to the essential level.

The photosynthesis process is known as the life triggering action of the plant, where the plant needs the sun light and balanced humidity of greenhouse. The required sunlight depends on the seasons. It is better to go for a cooler systems and humidifying systems to maintain a balanced atmosphere inside the greenhouse. This process is also useful during the winter seasons, where sunlight may possibly be inadequate. The heating systems and proper ventilation also should be considered to maintain a balanced life process for the greenhouse plants
