what we have seen the vertical farm is like this : people have made creative reform on land using , fully using vertical space such as vertically stacked layers, vertically inclined surfaces or integrated in other structures to produce food and medicine . Generally in these places growers utilize artificial light( https://www.atophort.com/?from=sopl) , environmental control , humidity control , temperature control and greenhouse gas control ,fertilization and any other handy means to help plants grow.here all environmental factors can be controlled. it is an ingenious way to produce fresh food in environments where arable land is unavailable or rare .and it is different from greenhouse growing. they make up modern indoor farming .
1.skyscraper
For the moment ,planting at Skyscraper is the most Way that can be hoped for to produce fresh food locally. Growing crops on high-rise buildings can increase the utilization of vertical space , at the same time , can support the food demand of growing urban population. it also make sense to reduce the need to reclaim more and more tracts of land and then ensure the green area of the planet. even though this high building planting technology are not quite ready yet ,it gives human being a guide line to deal with the issue that urban fresh food supply and the storage of fresh crop. as most people know , urban fresh food supply depends on the long-distance transportation technology and cool storage technology.
2.used warehouse
used warehouse , also named waste architecture.it refer to the buildings that become old and no longer put into use but don't reach the use limited time . over the years , used warehouse reuse is a new and relatively controversial topic. people devote themselves to how to reasonably reuse these idle used warehouse. it gives rise to a lively debate between environmental professionals, architecture and urban design experts. passing continually explore . they find an interesting use , that is using waste warehouse acts as a horticulture factory . this move is praised as a classical example of vertical farming . in this example , idle resource reuse actively and vertical space makes the best use .
3.shipping container
it is another reuse that similar to the used warehouse . all are taking full advantage of the Idle space resources. with the course of urbanization is accelerated unceasingly . cities turn into more and more crowed and tons of arable land is used to build housing construction.urban plantable ground is far to provide enough fresh food to meet the demand of the continually expand urban population.to relieve this supply pressure ,people have to pay attention to the vertical space . further give rise to vertical farming .
1.improve shortage problem of fresh food in city
just think of if this vertical farming are widely used in some challenging environments such as deserts, mountainside towns, and cities where lack of many diverse types of vegetables and plants. it would be a shake on fresh food supply chain of city . many cities no longer rely on the fresh food by long-distance transportation. That also is a effective improvement to the food shortage problem that urbanization brings to human beings . Precision agriculture methods and skyscraper-like farming design not only change the way that urban fresh food is offered ,but also provide a unprecedented new way to grow farming .
2.open another situation of modern farming
before using of innovative lighting (# Atop Light , Professional Horticulture Lighting Solution#)and nutrient delivery technology. the farming of old days rely on on the typical natural resources associated with plant production, such as soil and sunlight. the external environment like natural resources and climate have a big influence on the production process and they are not under control of human .the grower can not control the output of fresh food. and change in output leads to different levels of market volatility what people don't want to see. As a new discovery of the application study on horticulture , vertical farming comes into being. led grow light play an important role in environmentally controlled vertical farming. vertical farming gradually become a new form of modern farming.
3.maximally motivate the growing feature of plants
no matter what type vertical farming ,they are all interior environment. that is to say ,the plants of vertical farming are in a indoor controllable environment and can change growth condition with the need of the plants' growth . by virtue of not being affected by the nature condition.plants can grow constantly. the growth potential of plants get maximum motivation. for modern farming
cons
1. it seems strange to many people outside the professional field. why not use wide outdoor natural field but to choose this space-limited and huge consumption planting pattern.
2. some people think it is a way that need cost much higher energy to increase the productivity.
pros
1. of course there are also many people that have a positive attitude on vertical farming . The fact is there are still some countries lacking of arable land . they don't like many countries that own plenty of nature resource that can provide them with enough fresh food . fresh plants are treasure and rare for them. vertical farming rises gives them a unprecedented expectation.
2.it is regarded as a unique chance to grow food on place where land is rare , increase urban food production and lower the distance food transportation.
when comes to the artificial lighting that applied to boost the productivity of vertical farming . we have to say the forefront of plants light nowadays, led grow light. Previously , most of the vertical farming pioneers all used high power traditional lighting fixtures to supplement the needed lighting of plants . these lights consumed lots of energy and result in high cost to vertical farming growers , becoming a barrier of the development of vertical farming and making vertical farming in a gray area .compared with traditional and high-consumption lighting . led grow light makes it possible to use less power to offer sufficient photosynthetic photon flux. identical photon flux output efficacy 2.3 μmol /J , 600w led grow light is enough . however traditional grow light required power is up to1500w even higher .what' more ,led grow lights don't produce so much heat as traditional grow lights do.and that means vertical farming growers don't need to spend extra cost to settle the temperature control of vertical farming space .
The advent of led grow light has been contributing greatly to the development of vertical farming .
