This article talks about Hydroponics, an interesting method of cultivating plants without using
soil. The article starts by giving a description of Hydroponics, a brief historical background and
past usage, and ends on discussing the advantages and disadvantages of using the Hydroponics
way of growing plants.
Hydroponics (From the Greek words hydro, water and ponos, labor), is a way of cultivating
plants, using mineral nutrient solutions, in water. Soil is not used. Terrestrial plants may be
grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite,
gravel, mineral wool, or coconut husk. (http://en.wikipedia.org/wiki/Hydroponics)
It was discovered in the 19th century that plants absorb mineral nutrients as inorganic ions in
water. In natural conditions, and although soil also acts as a mineral nutrient reservoir, by itself it
is not relevant to the growth of plants. When the required mineral nutrients are introduced into a
plant's water supply artificially, soil is not required for the plant to grow.
Historically, hydroponics was defined as crop growth in mineral nutrient solutions, with no
solid medium for the roots. It is a subset if ‘soilless culture’, which only requires that no soils
with clay or silt are involved in plant cultivation.
Plants that are not usually cultivated in a natural environment are possible to grow in a controlled
climate system like hydroponics. During the time of World War II, produce was grown with
hydroponics on the dry Pacific Island, and this was the first time that hydroponics was used on
a large commercial basis to feed people. NASA has also looked to utilize hydroponics in the
space program. ‘Ray Wheeler, plant physiologist at Kennedy Space Center’s Space Life Science
Lab, believes that hydroponics will create advances within space travel. He terms this as “a life
support system with the biological component of growing plants—called a bioregenerative life
support system. It has several benefits for NASA.” These Scientists are researching how
different amounts of light, temperature and carbon dioxide, along with plant species can be
grown and cultivated on planets like Mars. (http://en.wikipedia.org/wiki/Hydroponics)
Hydroponics has taken plant cultivation to whole new level, and its methodology has attracted
even those who were scarcely interested in gardening or planting. But, what are the advantages
and the disadvantages of hydroponics cultivation?
There are several advantages to growing plants using the hydroponics cultivation method, which
excludes the use of soil. Growing time is comparatively much less and less space is required. As
well, it entails much less effort and the need for garden maintenance is reduced. Of course, it is
economical too, because water is conserved, the nutrients are recyclable, and pest, weed, and
diseases problems are better controlled. No soil bred pests are borne, there is higher productivity,
and finally, there is increased control over the plants rooting environment.
In spite of the above mentioned advantages, one should also be cautious though, of the demerits
of using the hydroponics cultivation methods. These include rather a steep set up cost, and
growers should possess the appropriate skills and knowledge to maintain maximum production
2. in commercial applications. While the threat of soil borne pests is absent, but because each plant
in a hydroponics system shares the same nutrient, diseases and pests can adversely affect each
plant. Also if there is an unfavorable change in climate, plants grown with the hydroponics
methods will wither or shrivel. Additionally, warm weather or decreased oxygen may curb
production and lead to a loss in crops.
In conclusion, it may be mentioned therefore, that it is necessary to consider both, the
advantages and disadvantages of hydroponics. One will therefore be able to make an informed
decision this will allow you to make informed decisions on what application is appropriate for
one’s respective requirement.
