Why Hydroponic Gardening Is Becoming More Popular

Hydroponic gardening has spiked in popularity recently
mainly because the quality and productivity of
hydroponically grown plants has been unmistakable.  These
plants grow faster and healthier than their soil-grown
counterparts.  This is due to the fact that they are grown
in an environment where there is a virtual limitless supply
of nutrients and water at their disposal.

These hydroponically grown plants, because they are not
grown in soil, do not need to fight off diseases and pests
which are natural in soil.  Pesticides can be decreased or
even eliminated.

And because the nutrients and water are delivered in just
the right proportion directly to the plant's roots, they
are better equipped to grow - faster, healthier, larger!

Hydroponically grown plants have the following benefits:

- They will provide high levels of nutrition

- They will be better tasting

- They will be rich in color.

In hydroponic gardening you will find that the crop's water
and nutritional needs are less complicated and sometimes
more effective.  Just a few simple measurements and it will
be evident what adjustments need to be made to the
nutritional balance in the water.  All the guesswork is
eliminated!

Although nutrient solutions are available from local
hydroponic suppliers and contain the correct proportions of
essential minerals, gardeners may also make their own
nutrient rich solutions.  This may sometimes require quite
a bit of extra work however.

When it comes to the growing medium that will provide
plants their nutrition, different materials have been
successfully used.  Materials such as sand, porous rock,
gravel, pumice, perlite,  and vermiculite have all proven
to be good choices. Fired clay particles can also be used.
These all are capable of providing a way of getting the
nutrient rich water into the plant's root system.

Also, there are various types of containers and pumping
arrangements for delivering nutrient solutions to the
garden and draining it back to the storage tanks for reuse.

If you're just starting out in hydroponic gardening you may
be wondering which types of plants are most suitable for
hydroponic gardens. The answer to this is tomatoes,
peppers, lettuce, and cucumbers. There are some types of
tomatoes that will continue to produce year round.

Some plants can be started from seeds and seedlings. In
this case use commercially available rock wool plugs
submerged in the media.  These make excellent incubators
for germination and seedling growth.

And since hydroponic gardens are self-contained, they can
be located just about anywhere space permits.  It is not
unusual to find these by windows, on rooftops, or in
closets.

A Greenhouse Provides Many Advantages for Hydroponic Gardening

Hydroponic gardening is the science of growing plants in a
controlled environment without soil - free from soil borne
pests and diseases. Hydroponically grown plants are raised
in greenhouses under carefully monitored and controlled
conditions. Gravel is normally used as the medium to
support the plant's roots within the hydroponics
greenhouse. Carefully mixed nutrients are then periodically
fed to the crops in liquid form - a method called
sub-irrigation culture. Once seedlings are planted almost
all of this work is done by automation. In these hydroponic
greenhouses sensors within the gravel are used to determine
when the plants need more nutrition and turn on the pumps,
giving the plants the just the right amount of solution.

These hydroponically grown plants are fed the exact
nutrients needed for rapid growth and volume production.
Some hydroponic gardeners use special tanks that are made
from big drums which are cut in half. The bottom of each
half is brazed with brass tubing. A hose hose is clamped to
one end of the tube. The other end is attached to a similar
tube which is brazed into a small can.

Inside the tanks the can is painted with an asphalt based
paint in order to prevent metal surfaces from rusting. The
tanks are filled with small sized gravel pellets.

The hydroponic gardening process starts with 'planting the
tanks' by first starting seedlings in carefully prepared
paper cups full of vermiculate to allow the hydroponic
solution to enter. After the plants are started, the entire
cup should be placed in the gravel. The plant's roots are
irrigated from below as the fluid flows down the hose and
into the gravel. The system is set up to ensure that the
crops are moist but are never flooded with solution for
more than a few seconds.

The advantages of hydroponic gardening in a greenhouse are
numerous. When crops are grown hydroponically, crop yields
are increased dramatically over conventional agriculture.
For example acre of land will yield five to the tons of
tomatoes. The same amount of space will yield 60 to 300
tons when grown hydroponically. A lettuce crop grown in a
hydroponic greenhouse will yield an increase of 12,000
pounds over conventionally grown lettuce.

Hydroponic gardening provides other advantages besides
increased crop yield. The hydroponic greenhouse environment
extends the growing season and doesn't require heavy labor.
And of course the obvious -there's no need for greenhouse
soil!
