Hydroponics supply innovative soil free agriculture of use to amateur and professional horticulturists alike. Growing crops need not be limited by climate and arable soil. Anyone with basic farming skills, can grow in a controlled environment agriculture (CEA) setting. CEA is not synonymous with hydroponics, however hydroponics partners with CEA.
Growing media are divided into natural and artificial. Natural media can be organic, rock or clay. Coir an organic media consists of ground coconut husks has perfect air to water ratio. Beware of lower grade coir as they contain too much natural salt. Perlite is used to increase air and lighten soil. Vermiculite holds an even amount of water and air. Pozzolanic lassenite is a type silica rich sedimentary rock composed of prehistoric diatoms.
Other media options include expanded baked clay. This is a type of shale, brand name Hydroton is neutral in pH, allows for air and water circulation around roots, but must be sterilized between use. Rock-wool is spun basalt and limestone. The stones are heated until molten then spun like steel wool. Polystyrene packing peanuts are sometimes used, however they may releases styrene into the nutrient mix passing it into the produce.
Watering systems consist of passive and active techniques. Subirrigation suspends the plant's roots above the solution. Aquaponics is a symbiotic passive system. Fish and plants mutually benefit each other thus both prospering. The fish fertilize the plants and the plants clean grow solution so it is not toxic to the fish. Many species are used, including, Murray cod, crayfish and catfish.
With Aeroponics, the plant does not grow in media, but is bathed by misted mineral rich formula. Therefore, aeroponics qualifies as an active delivery system. As with aquaponics, the bare roots are held into solution and are misted, not flooded. A mister applies mineral rich solution to the roots. The system uses no growing media, and water may be ongoing or scheduled.
Nutrient solutions come in commercially prepared pre-mixed containers or individual components offer the option of hand mixed. The gardener needs little chemistry knowledge a specialized solution. Many things can affect solution quality. The plant's consumption of the individual minerals or aggregate can change pH chemistry.
Though hydroponics has been used successfully for thousands of years, there are pros and cons. An obvious pro, is that it opens up avenues to grow food when the world's farm land is decreasing. Water conservation and reduced water consumption as the liquid is recycled. Even though nitrates are used, they are not released into ecosystem. Being a contained system, salmonella tends to grow, and damp-off is common depending on media used. Read more about: hydroponics supply
