The history of hydroponics
As seen in Growing Edge Magazine
Hydroponics basically means working water (“hydro” means
“water” and “ponos” means “labor”).
Many different civilizations have utilized hydroponic growing techniques
throughout history. As noted in Hydroponic Food Production (Fifth Edition,
Woodbridge Press, 1997, page 23) by Howard M. Resh: “The hanging
gardens of Babylon, the floating gardens of the Aztecs of Mexico and
those of the Chinese are examples of ‘Hydroponic' culture. Egyptian
hieroglyphic records dating back several hundred years B.C. describe
the growing of plants in water.” Hydroponics is hardly a new method
of growing plants. However, giant strides have been made over the years
in this innovative area of agriculture.
Throughout the last century, scientists and horticulturists experimented
with different methods of hydroponics. One of the potential applications
of hydroponics that drove research was for growing fresh produce in
nonarable areas of the world. It is a simple fact that some people cannot
grow in the soil in their area (if there is even any soil at all). This
application of hydroponics was tested during World War I. Troops stationed
on nonarable islands in the Pacific were supplied with fresh produce
grown in locally established hydroponic systems. Later in the century,
hydroponics was integrated into the space program. As NASA considered
the practicalities of locating a society on another plant or the Earth's
moon, hydroponics easily fit into their sustainability plans. This research
is ongoing.
But by the 1970s, it wasn't just scientists and analysts who were involved
in hydroponics. Traditional farmers and eager hobbyists began to be
attracted to the virtues of hydroponic growing. A few of the positive
aspects of hydroponics include:
• The ability to produce higher yields than traditional, soil-based
agriculture
• Allowing food to be grown and consumed in areas of the world
that cannot support crops in the soil
• Eliminating the need for massive pesticide use (considering
most pests live in the soil), effectively making our air, water, soil,
and food cleaner
Commercial growers are flocking to hydroponics like never before. The
ideals surrounding these growing techniques touch on subjects that most
people care about, such as helping end world hunger and making the world
cleaner. In addition to the extensive research that is going on, everyday
people from all over the world have been building (or purchasing) their
own systems to grow great-tasting, fresh food for their family and friends.
Educators are realizing the amazing applications that hydroponics can
have in the classroom. And ambitious individuals are striving to make
their dreams come true by making their living in their backyard greenhouse,
selling their produce to local markets and restaurants.
And now that so many people from so many different walks of life are
involved in hydroponics and its associated disciplines (such as aeroponics
and aquaponics), progress is coming faster than ever before.
