Dispelling Those Common Misconceptions about Hydroponics
Hydroponics is an often misunderstood part of the field of
horticulture. Let's separate the fact from the fiction and take a look at what
exactly hydroponics means to the world of gardening and food production.
The word hydroponics is derived from Latin and means
"working water." Hydroponic growing is the growing of plants without soil. All
of the nutrients plants normally get from soil are instead delivered to the
plants through water. Hydroponic gardeners add create nutrient mixes to add to
the water to give the plants everything they need to thrive.
One common misconception about hydroponics is that is a new
fangled, fashionable trend. Actually, it has been practiced for centuries. Even
the ancient Egyptians used hydroponics to grow their food. Great strides have
been made in the field since the 1970s, when agriculturalists began studying it
in earnest as an alternate means of food production, which perhaps is the
reason behind so many people thinking it is a new invention.
Contrary to popular belief, hydroponics has absolutely
nothing to do with genetically modified food. While genetically modified food
has been offered as a solution to solving global hunger, as hydroponics has, it
is a completely separate entity. Because genetically modified food is so
controversial, hydroponics sometimes gets a bad rap. In fact, hydroponic food
is 100% natural food, not modified in any way, and no chemicals are added to
the plants to make them grow that they would not get in traditional fields.
It's simply a different way to grow food; no genetic manipulation involved.
Some people believe hydroponics is bad for the environment.
Nothing could be further from the truth. Hydroponic plants require much less
water than traditional plants do - in most cases, they require around a tenth
of the water of traditional plants. The water is used for the desired plants
only; there is no water wasted on weeds. Also, there is no run-off of
pesticides into the surrounding environment. While hydroponic plants grown in
greenhouses do require a lot of lighting to sustain, using a lot of energy,
this cost is set off, and then some, by hydroponics' water conservation
potential.
Hydroponics also does not have to cost a fortune, despite
what many people think. True, nutrient mixtures and growth mediums are
expensive, but the field has come a long way in developing reusable materials
to balance some of these costs. Small-scale hydroponic operations should be no
more expensive than traditional gardens or crops of the same scale.
Nor is hydroponics an obscure gardening technique. It is
used in nearly every country on earth, and in some environments, it is the most
commonly used technique. For instance, in British Columbia, 90% of the plants grown in
greenhouses are hydroponic plants.
One thing people consider a benefit of hydroponics is
actually a myth as well. Hydroponics and organic farming are not synonymous.
Most hydroponic growers used pesticides on their crops. The bright side is that
these pesticides do not pollute the surrounding environment with rainwater
run-off like traditional crops do. It is possible to grow hydroponic crops
organically, but it should not be assumed that all hydroponic crops are.
One last misconception about hydroponics is that is it used
exclusively by the drug trade to grow marijuana. This is just not true. Some
illegal growers do use hydroponics, but many more people use this technique to
grow legal crops.
Hydroponics is destined to become more widespread in the
future, due to its food production potential and environmentally friendly
techniques. With more understanding of the field, hydroponic growers will find
it easier to convince the public about the viability of their crops.
