Hydroponics
Hydroponics has been around at least
since the hanging gardens of Babylon were
built around 600 BC. Hydroponics is the
process of growing plants without soil.
Hydroponics is also known as 'soilless' or
'soil-less' gardening, or "soil-less
culture". But how can you grow plants
without soil?
When growing plants in soil, soil
physically supports the plants; soil - if
properly fortified, porous, and watered
consistently - supplies nutrients that the
plants can uptake through photosynthesis.
So at the simplest level, if you can
provide the plant with physical support
and supply the nutrients that the plant
needs (via a nutrient solution), you can
do away with the soil. This is at the core
of hydroponics. But what are the
advantages?
Briefly, with soil growing, organic
matter in the soil must be broken down by
soil microbes into forms that the plants
can utilize. But how can the grower be
assured that his soil contains the right
mix of organics, microbes, and trace
elements for optimal growth of his plants?
For the home gardener he or she can mulch,
amend, compost, and add other
"supplements" to help make the soil porous
and add organics and trace elements. But
at the end of the day it's mostly "hit or
miss". So in most home gardens and most
large scale commercial production,
fertilizers are added to the soil. These
greatly increase yield but also tend to
kill the soil microbes - making continued
use of fertilizers a necessity and at the
same time eventually rendering the land
(at a commercial scale) fallow. At the
same time, chemical residue from the
fertilizers and nitrates inevitably
percolate into the ground water.
Should we be looking toward hydroponics
for large-scale commercial vegetable
production? Yes. Can we get back to
"natural", "organic" ways of farming in
soil without using commercial fertilizers
and pesticides? Yes, but not on a large,
commercial scale that would replace
current agra-business practices. There are
just too many people to feed and so-called
'natural', 'sustainable' agriculture
including biodynamic farming has not been
shown to give the yield we require to
sustain our current population. So maybe
we need to re-think our models for food
production. In our opinion we should
consider adding hydroponics to the mix of
competing agricultural technologies. We
need a paradigm shift based on science -
not magical thinking.
With hydroponics the plants are
physically supported in (generally)
non-organic media such as rockwool and
porous clay pellets. In several systems
(like ours) the individual plants are also
contained in net pots. Macro and micro
nutrients are provided to the plants in
solution form. Given the right conditions
the plants utilize what they need for
optimal growth. There is no soil, no soil
carried pests, no stress from soil drying,
no issues with non-porous soil, and no
unintentional percolating of nitrates into
the ground water as with all
soil-based agriculture (including growing
organically). If hydroponic systems are
properly designed, water is mainly lost by
plant respiration and minimally by
evaporation - not by water percolating
beyond the root level as in soil-based
agriculture and being lost to the plants.
As a major benefit, the difference in
yield between conventional agriculture and
hydroponic culture can be substantial.

Especially in these times of shrinking
resources, water shortages, ground water
contamination from agriculture, global
warming, and world-wide economic downturn,
we predict that hydroponically growing
vegetables for human consumption and
grasses for animal feed will become an
increasingly viable economic option over
present soil-based growing methods. It is
our contention that hydroponics is the
future of agriculture - especially in
regions of the world where soil conditions
are poor, temperatures are extreme, and
water supplies are limited. Along these
lines we are currently extending one of
our technologies to address large scale
hydroponic production of grasses for
animal feed. To our knowledge no such
technology has yet been implemented. Such
technology would be particularly
advantageous in regions of the world where
soil conditions and ambient temperatures
preclude economic, in-ground production of
wheat and grasses including alfalfa for
cattle and sheep production. Target
countries for this technology include
Saudi Arabia, Kuwait, Pakistan, and parts
of India.
On an individual level, we can increase
awareness of the large scale issues facing
current agriculture by growing a part of
our food needs at home on a small scale.
Growing "Victory-Gardens" was a rationale
for private citizens in the USA and
Britain for supporting war efforts during
the first half of the 20th century. During
the World Wars, many grew their own
vegetables to not only put food on their
tables but to help the war effort by
making more food available to their
troops. Our real "war" today has little to
do with global conflict; it has more to do
with ultimate survival. We have a separate
site, Victory-Gardens.com,
that you might find interesting to look
at. In order to effect change, we first
need to first be aware of the problem.
For the home gardener there are distinct
advantages to growing hydroponically
compared to growing in soil. In fact many
persons who are adept at killing their
plants either by neglect or by "kindness"
find amazing success growing ornamental
and vegetable plants hydroponically. But
getting started in hydroponics can be
daunting. There are a vast array of
hydroponic techniques, each with
advantages and disadvantages. And there
are literally hundreds of competing
nutrient solutions to choose from, each
claiming dramatic success. How to get
started?
This is where we come in. We specifically
designed our kits to make getting started
in hydroponics easy, fun, and successful.
The results - whether you grow lettuces,
mesclun mixes, herbs, jalepeno peppers,
tomatoes, edible or ornamental flowers, or
grasses such as wheatgrass, oats, barley,
rye, or rice - will amaze you. And the
best part is that you don't have to worry
about over or under watering (both of
which lead to trouble), or over or under
fertilizing.
Our kits were made to be used over and
over again. When you are ready to expand
your garden, you can dedicate separate
units to different crops. Depending on the
season, we usually have lettuces, basil
(we use lots of basil), jalepeno peppers,
marigolds, chard, and nasturtiums happily
growing in our Floating Gardens. We also
have renewable crops of wheatgrass and pet
grass mixtures growing indoors nearby a
sunny window or outdoors in our Grass
Garden kits. An added benefit to the
consumer is that our Floating Garden and
Grass Garden kits comply with the Consumer
Product Safety Improvement Act of 2008
(CPSIA, 2008). All of our kits are made by
us in the USA.
Update:, 2022: We decided to discontinue
our kits after have sold and manufactured
them for over 10 year. The market has
moved on and the current available
products are designed primarily on
aesthetic factors that were absent in out
kits.
