Imagine being able to grow plants and/or crops everyday of the year in
smaller spaces without the use of any soil. Hydroponics is a soiless
agriculture that does just this. The idea for the use of plant growth without
any soil was developed in the eighteen hundreds. Hydroponic gardening is an
old idea yet new methods have been formed to give you three hydroponic
gardening options. These three options are defined by uses of different
mediums. Fifteen to twenty minutes of care per day can produce beautiful
plants and enough food to feed one family a day. Hydroponic environments
are indoors so weather changes do not effect them. All mediums use certain
solutions which vary with different types of mediums. Hydroponic
environments are easy to build and easy to take care of and the advantages
are great. This form of agriculture is one of man's simple yet helpful ideas
that can better the earth and it's people.
Hydroponics is a soiless agriculture that was originally used for
growing plants in the winter. Hydroponic agriculture is also known as soiless
agriculture, nutriculture, or chemical culture. Hydroponic plants can be
gardened in several different ways. Hydroponics uses different nutrient
solutions to ensure better plant life. Plants need nutrients and moisture to
survive and soil provides this. When hydroponic gardening is used these
necessities increase and the plant lives a fuller and more beautiful life.
As it was already mentioned, the advantages of hydroponic gardening
are great. It was also already mentioned that hydroponic gardening reduces
the amount of space used and can be grown all year long. But this is only the
beginning of the advantages of hydroponic gardening. People who have
hydroponic gardens don't have to put up with soil-borne pests and diseases
and they don't have to pull any weeds. Food crops grow and mature at a
much faster rate in non-soil mediums than in soil mediums ( a medium is any
surrounding substance or environment ex: soil, dirt, sand, or water ) this
produces greater amounts of produce or surplus. Fertilizer and water are
saved with the use of a non-soil medium because they can be reused. Also
the competition between roots is eliminated. All and all the plants energy is
spent more on the vegetation and flowering process because the mediums
provide more air.
The concept of Hydroponics was originally retrieved from the ancient
civilization called the Aztecs. The Aztecs' had floating gardens which circled
their great city. These rafts were called chinampas which grew vegetables
and flowers. In the sixteen hundreds early scientists tried to copy this idea
and were only some what successful but found that the purpose of soil was to
hold plants upright. Soon scientist in the eighteen hundreds modernized these
old ideas. In 1860, Professor Julius von Sachs discovered ways to make a
nutrient solution that could be dissolved in water and plants could live in
successfully. Only until 1936 did the first hydroponic garden grown become
grown. It was grown by W.F. Gericke and J.R. Travernetti of the University
of California.
There are three methods used to grow hydroponic gardens. These
methods are separated by which medium growth occurs in. The first method
is called water culture. Water culture is a method where plants grow in water
or in water and a nutrient solution. The next method is called sand culture.
Sand culture is the growth of various plants in sterile sand using water and a
nutrient solution. The last method is called aggregate culture. Aggregate
culture replaces sand and uses gravel, vermiculite or other such substances to
grow plants also using water and nutrient solutions. All of these methods can
grow almost any type of plant. Other substances that are used in hydroponic
growth include perlite, rockwool, geolite, crushed rocks, bricks, shards of
cinder blocks, and Styrofoam. Currently new methods are being formed to
grow plants in different hydroponic environments. Some new forms of
hydroponic gardening include suspending the roots of a plant in the air of an
enclosed chamber. The plant is then misted every day with a nutrient
solution.
Hydroponic plants require very minimal care. To build a hydroponic
environment takes a little more work than the care of these plants, but not
much. A container in which hydroponic plants grow in is called a hydroponic
unit. Almost any container will do to make a hydroponic unit. One can make
a hydroponic unit, basically, in three...
