Aquaponics research
Now while aquaponics remains very promising technology, it is still in its infant stages. Methods of delivering phosphorous and potassium remain an issue because it poisons the aquaculture, Many have tried and failed to develop a system which has the efficacy of simple hydroponic system with chemical nutrients. In order for aquaponics to be effective plants must get all of the different nutrients they need while maximizing the oxygen to their root system. The fish must be hardy and perfectly balanced to achieve the highest PPM of nitrates for the plants, but still low enough for the fish to survive. The bacteria must thrive and biofilters must be set up for optimal nitrate conversion. the complexity of these conditions in addition to the inability to safely deliver high amounts of “Bloom” fertilizers during flowering have limited this system to vegtative plants.


Hydroponics is by & large very reliable, Easy to operate, effective, very versatile, and well researched. A quantity of nutrients is added to the water and the system delivers the nutrients to the roots through various mediums and methods of operation. Plants grown hydroponically grow much fast than plants grow in typical soil. There are many types of hydroponic systems. The most effectiv are the systems which deliver the maximum amount oxygen to the roots of the plant. Stimulatng root growth facilitates rapid overall growth. In hydroponics the is a toxic buildup of acids, salts, and residue build up. Frequent maintenance is required. PH much be adjusted as changes occur in the water chemistry. Eventually this toxic water is wasted and dumped, polluting the environment.

Aeroponics is the most effeicient way of growing plants, and achieves the fastest growth rates. Plants grown aeroponically do not use medium but are grown in air culture; their roots are suspended in a fine mist. Because water in mist form contains more surface area than water in droplet form, the roots receive more oxygen. The roots grow faster, and are able to absorb higher nutrient levels. But on the down side Aeroponics can be very difficult to design, Because to utilize the technology at its best the water droplets must be less than 50 microns. This requires an expensive high pressure pump and special misters. The misters mineralize and clog over time and
must be cleaned regularly. Also, because of the moisture levels in the air culture surrounding the roots, hydrogen peroxide must be added to prevent pathogens and fungus. If the electrical supply is compromised for even a few hours, the plants perish.

Concepts of Aquaponics

The concept of aquaponics:
Fish produce wast, which is broken down by bacteria into nitrites, and then by another bacteria into nitrates. Water is circulated from the fish tanks to hydroponic growbeds. The plants eat the nitrates, which in turn filters the water for the fish. there are also exchanges of carbon dioxide and oxygen, as well as micronutrients. this system emulates what takes place in nature. Aquaponics is inherently organic and can be run entirely chemical free. Aquaponics is simple but it must be balanced in order to fully work. It can take several weeks or even months to get a system working properly, and there are a lot of potential downfalls if built incorrectly, The system must be cycled just like a fish tank. the bacteria must flourish. Also the fish need to be balanced with the plants in order to obstain results.
