Advantages and Disadvantages Plant Grow Hydroponics

Advantages and Disadvantages Plant Grow Hydroponics - Hydroponics is derived from the Greek hydro means water and ponous means work. Corresponding meanings, farming hydroponic farming is a technology that uses water, nutrients, and oxygen. Some of the advantages and disadvantages of hydroponics system compared to conventional agriculture are:

Excess hydroponic systems, among others:
More efficient land use
Production plants without using soil
The quantity and quality of production is higher and cleaner
The use of fertilizer and water more efficiently
Pest and disease control easier

Hydroponic system deficiencies, among others:
Require substantial capital
In the culture of the substrate, the substrate media kapisitas water holds less than the media so that the soil will cause the withering plants fast and serious distress.

In the world, growing hydroponic first time that hydroponic substrate, the substrate after hydroponics, hydroponic NFT (Nutrient Film Technique), then develops a hydroponics aeroponics which empowers the air.

Hydroponic substrate. Substrate hydroponics system does not use water as a medium, but using a solid medium (not soil) that can absorb or provide nutrients, water, and oxygen as well as supporting the roots of plants as well as soil functions. The materials can be used as a growing medium in hydroponics substrate method is rice husk, sand, gravel, pumice, cocopeat, rockwool, and sponges. Such media must be sterile, can store water temporarily, porous and free of nutrients. The media serves as a place to store water and nutrients while it serves as a beachhead roots. The drip irrigation system is used to supply the nutrients from the water flushing nutrients to plants using

Hydroponic NFT (Nutrient Film Technique). The word "Film" in the film technique hydroponic nutrients showed a thin stream of water. Hydroponics uses only water flow (nutrient) as a medium. NFT is a model of cultivation in conjuction with the roots of plants in a shallow layer of water. The circulating water and nutrients needed by plants. Rooting can be grown in nutrient solution for rooting around there is a layer of nutrient solution, then the system is known by the name of the movie nutrient technique.

Aeroponics. Aeroponics comes from the word meaning aero air and ponus which means power. Aeroponics can be interpreted to empower the air. The working principle of aeroponics which ejects nutrient solution in the form of mist to the roots of plants. The nutrient solution will be absorbed by plant roots. Plants grown in aeroponic system by hanging so that plant roots dangling in a tub. Base of the stem is inserted into the strands of styrofoam that has been hollowed into a stand.
