Hydroponics
Hydroponics is a Latin
word that means "water working." Hydroponics is the technique
or practice of growing plants (without soil) in water containing
dissolved nutrients. With a flow of highly oxygenated, nutrient
enriched water, hydroponics allows plants to flourish.
In soil, decomposition
breaks down organic matter into food that plants feed on. For a
plant to receive a well balanced diet, everything in the soil must
be in perfect balance.
With hydroponics, water
dissolves salts to allow absorption directly by a plants' root system.
These ideal conditions can be very rare in soil due to contamination
and inherent imbalances.
Since a perfectly balanced
hydroponics nutrient solution is contained, it does not harm our
environment like runoff from fertilized soil. Very little water
is lost to evaporation owing to its application in areas subject
to drought.
To support the plants
in this type of system, an inert soil-free medium like fiber, sand
or stone, may be used to anchor the roots. A hydroponics system
is designed to be very porous for excellent retention of air and
water that's necessary for a healthy plant - roots do need to breathe!
In addition to a perfectly
balanced diet, plants grown using hydroponics have their food and
water delivered directly to their roots. This way, the energy normally
used to develop long roots can be redirected to growing more plant.
With the proper exposure
to natural sunlight or supplemental growing lights, your hydroponics
crop can grow many times faster, bigger and healthier than those
grown in soil. |
