ydroponics technology that is nothing more than growing plants in water enriched with nutrients instead of soil. “Hydroponics” is not a completely uniform concept. There are currently many ways of soilless cultivation of plantsinclude the terminology known as 'Wick' where the plants are placed in a chemically inert, root stabilizing medium (e.g. expanded clay or coconut), and water with nutrients is supplied to the root zone through an absorbent ‘wick’ immersed in the tank below. Second are 'Air-Gap' at the lower part of the plant’s root system is immersed directly in water, and the upper part is above it. Other component include 'DWC and raft' or or Deep Water Cultivation in which plants are placed on a floating surface and their roots hang down in water filled with nutrients. Last component are Ebb and flow so that the plant roots are placed in the medium and water is pumped into the root zone at regular intervals. Water is allowed to flow freely through the medium into the tank. For component suh as 'Top feeder' able for the system is very similar to ‘ebb and flow’ except that the water does not flow into the tank and is pumped out of the medium. Some people mention about NFT or Nutrient Film Technique that the plants hang attached at a delicate angle over a constantly flowing, thin layer of water with nutrients. The needs of 'drain’ is a method of individual irrigation of plants in small quantities, which allows to accurately regulate the amount of water and nutrients supplied. Blog writer also aware of 'Aeroponics' in which the plant roots hang in the air, without medium or contact with the liquid water and nutrients are supplied in the form of an aerosol.
hy would hydroponics be better that ‘traditional’ agriculture?. For me that hydroponic systems win supporters both among amateurs and entrepreneurs in many country include Malaysia by producing plants on an industrial scale. The claim that it was quite a lot advantages over the traditional agriculture in terms of efficiency and ecology. For the first advantages a properly selected nutrients circulating in water logically are more easily available for plants. Therefore at the later stage they allow to obtain higher yields and much faster than in the case of plants cultivated in soil. The crops can be harvested throughout the year, regardless of weather or climatic conditions. However for hydroponic crops actually there is also no problem of ‘soil fatigue’. Second advantages are the plants grown using hydroponics have much less chance of developing infections from soil diseases. A closed and well-controlled space hinders the invasion of insects and so the use of pesticides, decreases or even ceases to be necessary. When it comes to nutrients in which for the case of closed-loop cultivation are used repeatedly better do not go to the environment as so-called “runoff”. Thanks.
