AEROPONIC GREENHOUSE SYSTEMS
Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium (known as geoponics). The word "aeroponic" is derived from the Greek meanings of aero- (air) and ponos (labour). Aeroponic culture differs from both conventional hydroponics, aquaponics, and in-vitro (plant tissue culture) growing. Unlike hydroponics, which uses a liquid nutrient solution as a growing medium and essential minerals to sustain plant growth; or aquaponics which uses water and fish waste, aeroponics is conducted without a growing medium. Because water is used in aeroponics to transmit nutrients.
There are so many advantages of this technology, these are:
• No need to dispose of growing media after production cycle.
• Studies have shown that this method of growing can actually help your plants germinate and grow faster. When combined with the right type of nutrients, this can translate into extremely fast harvests and can allow you to enjoy the fruits (and vegetables) of your labor much much sooner.
• In aeroponic systems the total yields are between 2 to 5 times more than other technologies.
• The plants receive more oxygen. The exposed roots quickly absorb oxygen from the air, much faster than roots that are embedded in soil. Aeroponic plants and crops also tend to grow faster than those planted in soil, resulting in quicker harvests. One reason for the quicker growth is that more oxygen allows for the faster absorption of essential nutrients. Plants and crops, like humans, need certain nutrients to grow, especially nitrogen, phosphorus and potassium.
• There is no dirt or debris to clean from the roots, which can be a relatively lengthy process. Moreover, hydroponic plants are not usually treated with pesticides or other harmful substances. Thus, growers and buyers do not have to worry about removing these pernicious elements.
• Aeroponic systems can limit disease transmission since plant-to-plant contact is reduced and each spray pulse can be sterile. In the case of soil, Aggregate, or other media, disease can spread throughout the growth media, infecting many plants. In most greenhouses these solid media require sterilization after each crop and, in many cases, they are simply discarded and replaced with fresh, certified sterile media. A distinct advantage of Aeroponic technology is that if a particular plant does become diseased, it can be quickly removed from the plant support structure without disrupting or infecting the other plants.
