Hydroponic Systems And Techniques Explained

Business and Management , , 0 Comments

Hydroponics is a method of growing plants in water without soil. Plants can be fed in a variety of methods using inorganic nutrient solutions. 'Hydro is Greek for water and' ponos' is Greek for labor. Earthly plants can be grown with a good mineral nutrient solution or sometimes in an inert medium such as mineral wool or gravel. The growth is generally monitored by plant area computerization systems.

There are six main types of hydroponic systems:

Aeroponic – this method involves growing plants in a closed environment with the help of nutrients from escaping.

Drip – This method uses a tray of growth are suspended above the reservoir, which is filled with water and nutrient solutions. A pump was placed in the reservoir is then connected to the growth tray, providing nutrients through short 'dripping'

Flood and drain (aka Ebb & Flow) – in this method, the plants growing in individual blocks in a large shallow tray. Tray flooded with nutrient solution to the roots wet and then dried to allow air tray.

NFT (Nutrient Film Technique) – this method requires a constant amount of nutrients flowing through the pipe over the roots and then back to the nutrient reservoir. Plant roots are suspended in the air while the nutrient solution sprays on roots, referred to as a thin film.

Water Culture – in this method, the plants are suspended in a Styrofoam platform which floats on the water and a container of nutrient solution.

System Wick – This method is the simplest of all the hydroponics system. This method has no moving parts and the system consists of seedling pots, growing media and 'axis'.
