How does Greenhouse work? (Detailed Report)


How does Greenhouse works? (Does & Don’ts)

A greenhouse is a glass made box or more than a box varies in size. It is a man made atmosphere. It is used to plant vegetables, fruits, flowers and transplants in warm climate which is provided within this glass house such as artificial heat, light, humidity and required nutrients. It works as the, rays from sun come to earth and warm the earth’s surface and because it is made of glass so radiations from sun comes into glasshouse but do not escaped back to atmosphere trapped by the glass walls and roof of the green house and thus greenhouse remain warm even at night and allow plants and vegetables to grow in warm climate continuously. Greenhouse is an artificial source of life for plants when there is no sunlight or heat for their growth (cold days of winter in Ice-lands and other colder regions of earth).

The atmosphere within the greenhouse is same as earth’s atmosphere. The rising amount of heat in earth’s atmosphere e is the result of increase in greenhouse gases like carbon dioxide, methane, nitrogen oxides and water vapours. These gases gathered around earth’s boundary and stops sun rays to go back to space and thus earth’s atmosphere become warmer and cosy. This is same with the greenhouse, in atmosphere greenhouse gases trap the sun radiations and in greenhouse the glass roof and walls trap sun radiations and do not allow them to escape out and turn these rays into heat. Now a days the rapid increase in greenhouse gases from different human resources (automobiles, appliances, burning of fossil fuels etc) stronger the effect of greenhouse. Within greenhouse light, heat and growth nutrients are provided to plants for their survival and efficient growth. Greenhouse is made of transparent material and at the place where there it absorbs more of sun light and at night escape less.

The warmness of greenhouse doesn’t depend upon the amount of sunlight but it depends upon the material by which it made of. If the material is of high density then it absorbs more heat and cause plants to grow faster. When there is no sun in colder days there is need to provide artificial heat by space heater or with the help of another source of heat, so that plants continuously grows. Sometimes artificial heat source is also used to provide temperature at night when there is no enough heat stays within greenhouse. A greenhouse is specifically used to maintain optimum temperature for plants in contrast with outdoor harsh temperature. The only purpose of greenhouse is to grow plants with good climate and sufficient water source. Within greenhouse when plants heat up they cause humidity and it helps plants to restrain in water. In greenhouse you can grow tomatoes, strawberries, onions, garlic, pepper, corn, carrots and different types of flowers by providing light, energy, humidity, water and nutrients in standard amounts. Within greenhouse it is not necessary to plant the same type of plants or flowers; you can also grow different types by providing them their necessities. When owning a greenhouse kept in mind few things to cultivate healthy and growth worthy plants;

  • Be aware with the amount of temperature that is sufficient for healthy plant growth (nor to high neither to low)/ Maintenance of standard temperature
  • Different plants have different growing needs so kept in eye with every of these nutrient, light and heat needs.
  • Consider the size and angle of your greenhouse, it should be in the correct angle where its roof absorbs high amount of sunlight and release less at night.
  • If you are thinking about using wood benches in your greenhouse then make sure this wood is rot-resistant.
  • Use good quality thermometer for greenhouse to measure ventilation inside it.
  • Check manually required amount of light by each plant.
  • When there is need to provide heat through artificial heaters, it should also decide earlier so plants don’t face a bit lake of heat to precede photosynthesis.
  • Know the best designs of greenhouse which ensures high rate of productivity. Broad roof greenhouse design is more suitable.
  • Essential knowledge about plantation is necessary for choosing seeds and fertilizers.
  • Knowledge of chemistry is necessary for the person who handle with greenhouse for dealing with chemical deficiencies and diagnoses in plants.
  • Cutting and manipulation of growing plants and flowers daily or weekly should be planned.
  • Have check and balance on growing or completely grown plants to avoid overgrowth of vegetables and fruits.
  • Effective greenhouse management requires a lot of experience and tips.
  • Make your greenhouse structure as it absorbs solar energy according to their utilizing need.

Plantation in greenhouse is beneficial as within it we can plant vegetables and flowers according to our own requirements. In greenhouse plants, inhale carbon dioxide at night but in outdoor environment at night, carbon dioxide is not present in atmosphere and thus photosynthesis stops and respiration occurs but in greenhouse plants carry on photosynthesis even at night. When thinking about a greenhouse building, consider a fertilize land free from pests and bacteria. In this way we can also control healthy growth of plants only by considering carefully. When plants grown in greenhouse there is no fear about bad weather or whatever the season is. Greenhouse is beneficial and widely used for colder regions and in extreme environments where sun is frequently shines to grow vegetables. In outer atmosphere the PH of rain and heavy or slow rain fall also affects the crops productivity but in contrast greenhouse is varying from all these short comings. It protects plants from excess cold and heat of outer atmosphere. The use of greenhouse building increases in this technological era because the industrial revolution leads to cutting of forests and deforestation cause increase in concentration of carbon dioxide in atmosphere.

No trees to absorb carbon dioxide and thus this excessive CO2 distracts in atmosphere. This CO2 trap more sun radiations and warm earth’s climate. Deforestation also leads to soil erosion and barren land which is not used for healthy plant cultivation. No doubt greenhouse has benefits but there is also need to takes some initial right movements. A right or experienced first move can green your house/greenhouse but your un-experienced attitude towards selection of seeds, fertilizers, pesticides, land selection, season of cultivation and maintenance of optimum temperature may build a greenhouse with no future foundations. Owning a greenhouse is a big responsibility, the person should know all the facts about cold – season crops or flowers like these crops are cultivated in March and warm – season crops or flowers are cultivated in April or May because these are anti congelation. Solar heat trapped by greenhouse walls should be equally circulated within the whole room covered by transparent glass so all the plants inhale sunlight and heat to grow properly. So it is obvious that greenhouse is used to trap solar radiations and turn these radiations into heat and light for the growth of plants inside it. But how it effect earth atmosphere and cause threat to human life.

Greenhouse gases (CO2, NO2, water vapours, methane etc) which are produced as a result of various human activities, trap some of the UV radiations coming from sun and do not allow them to go back to space and cause earth’s atmosphere get warm and cosy day by day. After CO2 water vapours are also a cause of greenhouse effect like water vapours are present in atmosphere as a gas and cause fluffy clouds and the white tops of these clouds reflect heat back to atmosphere and cause greenhouse effect. Warmer atmosphere melting of glaciers and Ice- lands which leads to rise in ocean level and acidity of ocean’s water. This increased acidity causes infertile and acidic soil and this soil effect the productivity and quality of crops. If we are continuously releases this amount of greenhouse gases in the atmosphere then there would be a time when there is no place to establish an artificial greenhouse on earth as well. Greenhouse works on the principal of quality through time management and if our land is used wisely then it yields maximum. The use of greenhouse increases because people become more health conscious and they prefer to cultivate vegetables free from bacteria and pests at home even at very small scale.

A number of greenhouses are builds to support food companies and flower dealers who do not compromise on their sales which are affected by seasons if they were rely on natural plant or vegetable cultivation process. Since the earth’s atmosphere gets warmer the use of greenhouse increases almost in all the countries of world because it has its own unique and under control closed environment. It allows growing vegetables, fruits, flowers and transplants vary from season, due to greenhouse the specificity of crops of colder or warmer season almost diminishes. Now people can avail fruits and vegetables of cold season in warm season as well. A crop, vegetables and fruits are productive and quality being if they are kept under proper greenhouse management. A poor greenhouse balance of heat, light, water and nutrients cause limited growth of plants within it.
