Jenis-Jenis Sistem Hidroponik / Types Of Hidroponic System

1) Systems categorized by where the roots are located:

Liquid Culture: The roots are hanging into the nutrient solution which can be either in the form of a liquid or a mist.

Aggregate Culture: The roots grow into an inert medium such as sand, gravel, Rockwool, perlite, vermiculite, peat moss, foam, coconut coir, etc. and are then irrigated with a complete nutrient solution.

2) Systems categorized by what happens to the nutrient solution:

Open: The nutrient solution is distributed from a reservoir to the plants and is then “drained to waste” (i.e., not used again).

Closed: The nutrient solution is distributed from a reservoir to the plants. After passing through the root zone it is collected and reused. In large systems the solution may be analyzed, then modified by the additions of water, acid/base, and/or various inorganic elements to return the solution to the appropriate inorganic mineral composition (and EC) and pH. The solution may also be sterilized (UV light, ozone treatment, etc.) so that any plant pathogens, picked up in the solution from perhaps one or a few infected plants, are not subsequently spread to all of the plants.

Drip Irrigation System of Precision Farming in the US modern farm

This method shows the system of the modern farming concept in which we used to call FERTIGATION (Fertilization and Irrigation) or Drip Irrigation whereby the hidroponic fertilizer (in the form of liquid and pre-determined concentration using the calibrated E.C meter) is transported through a P.E and Poly piping and end at the microtube dripper to individual unit of plant. By using this method, each plan is getting the same and consistent amount and also the same concentration of fertilizer and thus, optimise the fruitings
