Hydroponics Faq: Getting Started In Hydroponics
Author: Harry Gurney

* What is hydroponics?

Hydroponics is commonly referred to as "the cultivation of
plants in water." However, study shows that various media can
support the growth of the plant, so the definition was
broadened to "the cultivation of plants without soil."

* What plants can be grown hydroponically?

Theoretically, most plants can be grown hydroponically, but in
practice, some are easier to grow than others. Among the easier
ones are lettuce, basil, mint, tomatoes and peppers. Plants like
watermelon, squash and strawberries are harder to grow.

* What are the advantages of hydroponics?

The most apparent advantage of hydroponics is its manageability
in controlling the plant-growing environment. Other benefits of
hydroponics are:

- Less water used

- Lower labor costs

- No need for expensive soil fertilizer

- Certainty of plant production

* What nutrients do hydroponic plants require?

Nutrients are needed by the hydroponic plants in order to grow
and promote production. Basic nutrients consist of the
following:

Water - There should be an adequate amount of water for optimum
growth.

Oxygen - It is necessary to bubble air around the roots of the
plants to supply sufficient oxygen.

Carbon Dioxide - It is required along with hydrogen for
producing carbohydrates.

Minerals - Including potassium, nitrogen, calcium, magnesium
and sulphate.

All of these nutrients must be present for a hydroponic plant
to grow.

* What different growing media can be used in hydroponics?

The different growing media used in hydroponics are:

Expanded Clay - enables nutrients to be controlled by the water


Rockwool - made from basalt rock

Coco Coir - made from the husk of the coconut

Perlite - very lightweight volcanic rock

Vermiculite - often referred as light pebbles

Oasis root cubes - suitable for large-scale nutrient film
growers

* How much time does a hydroponic garden require?

Starting a hydroponic garden requires time commitment and
dedication. It needs plenty of time if you want to make sure
that the plants are in good condition at all times. At first,
it will also take you longer to mix the nutrient solution. From
time to time, it is necessary that you check on the pests or
diseases that might attack your plants.

The time involved in setting up your own hydroponic garden also
depends on how big and complex it is, as well as the type of
plants you decide to grow.

* What equipment do I need to start growing hydroponic plants?

Necessary equipment should be prepared before you can start
hydroponics. The equipment can be purchased at most nurseries
or garden centers. You will need:

- Gallon buckets

- A small pump

- Drip emitters, hose and connectors

- Rockwool (absorbent type)

- Geolite, lava rock or stone pebbles

With this equipment, you can proceed with your hydroponics
planting project.
