There are geothermal heated greenhouses that support a plant’s life process in changing climate conditions. These heated greenhouses consume a large amount of heat energy when it comes to gardening and agriculture. However, it should be satisfying to most gardeners because of the good results they provide to the growth and development of a plant.
Most of these energy needs and geothermal conditioning are basically structured according to the environmental and ecological orientation of most greenhouses. The energy needs are adjusting based on the certain climate changes that may occur from the different seasons of the year. They are built with light materials that have minimal insulating features to create a stable climate inside the greenhouse.
The external climate brings a different approach to an internal climate system in a greenhouse. The necessity to have a greenhouse may occur during colder seasons where there is limited sunlight. The main purpose of having an internal climate system is to optimize the needed factors for plant growth. The internal climate factor that will be obtained is the photosynthesis process involved in environment and plant reactions.
Photosynthesis is the reaction process between the plants and the sun’s solar radiation. This means that carbon dioxide is supplied by sunlight to create a life process for the plants. There is a certain amount of climate heat that is calculated to designate the needed supply for lighting and heating. The greenhouse climate is essential in calculating the needed heat and coldness to the demand of the greenhouse.
The existence of heating and humidifying systems can adjust to the conditions of any external climate changes. Some processes that take part to the continuous energy balance maintained in any greenhouse is the water transport through the soil, plant canopy, and air. The formation of chlorophyll affects the entire internal climate. This happens because of the effect of heat transfer, solar light, oxygen and carbon dioxide cycle.
Here are some factors in valuing each aspect of parameters that is important to the climate condition and character of the internal climate.
1. The air movement in the greenhouse may influence the needed heat transfer on the air composition to the plant canopy. It also involves the process of water transfer to the plant canopy. This process will sustain the energy balance needed by the plants to continue a healthier life process in the greenhouse.
2. The heating installation is essential for the proper distribution of temperature inside the greenhouse. It also allows a controlled air movement to maintain the humidity and moisture in air characteristics that is affected by the external climate changes.
3. The water transport in the greenhouse also plays a big role in sustaining the photosynthetic process in the environment the plants. The roots have aspects pertaining to cultivation base that offers a needed amount of water, which is also needed in humidity and greenhouse temperature.
4. The air temperature affects the whole energy state inside the greenhouse. It is the connective heat supplied in the different aspects of the environment. The characteristic of the air movement in the greenhouse influences the leaves and stems of each plant.
5. The light factor is very essential in producing photosynthesis reaction to the plant’s canopy and to the formation of carbon dioxide that serves a big role in the respiration of the plants. Its necessity takes significance on the plants’ development and life process inside the greenhouse. Solar radiation provides instant intensity of light spectrum to supply the needed warmth and heat energy during colder seasons.
6. The soil or ground base temperature affects the condition of the climate inside the greenhouse as well. The significant parameter involves the transfer of heat energy directly to the ground structure, which includes the roots and the water flow system that partakes in the plants’ growth.
7. The carbon dioxide concentration also takes part in the life process inside the greenhouse. The normal average of carbon dioxide concentration in the external air atmosphere is 0.03%. This is important to maintain a balanced temperature and humidity density in a greenhouse.
It is important for a greenhouse to have installed systems to create an environment that will provide continuous life process for plants in changing climate conditions. A well-planned greenhouse climate should assure a person of having proper distribution of light, temperature, water, carbon dioxide, and other essential factors needed for every plant to grow.
