Hydroponics is an environmentally friendly, high tech way of growing more plants in less space. This course is a very solid training program aimed at people who want to work in the hydroponic industry, or persue it as a serious hobby.
There are six basic types of hydroponic systems: • Wick • Water Culture • Ebb and Flow (or flood and drain system) • Drip (with either a recovery or non-recovery process) • N.F.T. (Nutrient Film Technique) • Aeroponic This course relates to all of these systems and provides a sound foundatiuon for serious hydroponic culture whether as a commerrcial grower or amateur enthusiast.

EXTRACT FROM COURSE NOTES:
WHAT MAKES UP A SYSTEM?
A hydroponic system comprises the following components:
The Location
This is a key factor because it influences everything else.
* If the system is indoors, then the environmental conditions are being controlled. There will be fewer temperature extremes and fluctuations; wind exposure is minimised; pests and disease problems may be reduced.
* If the system is outside it will be exposed to temperature and light fluctuations, drying and damaging winds, and rain which may dilute the nutrient solution. Outdoor systems can be vulnerable to damage from dogs, cats or other animals, but may have fewer fungal problems (due to reduced humidity).
The Container or Bed
The roots (as well as the nutrient solution and medium) need to be contained in something.
* You may use gravel, sand or perlite contained by bags, pots or tubs.
* You may have rockwool fibre or scoria contained in a raised bed built from timber, metal or concrete.
You may use polystyrene boxes, hanging baskets, prefabricated fibreglass tanks etc. the list of possibilities is endless.
Watering/Nutrient Application Equipment
Nutrient can be applied dry on the surface and then watered in or mixed with water and applied as a nutrient solution.
Solution may be applied automatically at predetermined times or as required.
It may be applied at the bottom of the media and allowed to move up via capillary action, or alternatively at the top and allowed to filter down.
It may be pumped on, or moved manually or by gravity.
Excess may be collected and reused, or allowed to be lost after passing through the media.
Trellising
This is not always necessary. When growing tall or creeping plants: (eg. tomatoes, cucumber, chrysanthemum, carnation, roses), the root medium alone may not be strong enough to support the plant. A trellis of wire mesh, strings or stakes may be necessary to just prevent the plants from falling over and being damaged.
Root Media
The media which the roots grow in affects your decisions about all of the above. You must consider rooting media with respect to its ability to hold water, air, nutrients, support the plant etc.
