Basic Hydroponic Systems and How They Work

Basic Hydroponic Systems and How They Work There are 6 basic types of hydroponic systems; Wick, Water Culture, Ebb and Flow (Flood & Drain), Drip (recovery or non-recovery), N.F.T. (Nutrient Film Technique) and Aeroponic. There are hundreds of variations on these basic types of systems, but all hydroponic methods are a variation (or combination) of these six. Scroll down this page (or click on the system names) to see drawings and a description of each type of hydroponic system. WICK SYSTEM The Wick system is by far the simplest type of hydroponic system. This is a passive system, which means there are no moving parts. The nutrient solution is drawn into the growing medium from the reservoir with a wick. Free plans for a simple wick system are available (click here for plans). This system can use a variety of growing medium. Perlite, Vermiculite, Pro-Mix and Coconut Fiber are among the most popular. The biggest drawback of this system is that plants that are large or use large amounts of water may use up the nutrient solution faster than the wick(s) can supply it.

Evaluating irrigation scheduling of hydroponic tomato in Navarra ...

The correct supply of water and nutrients is important in hydroponic growing systems in order to use water efficiently, avoid stress situations, and control production. The present study was conducted to evaluate two irrigation scheduling techniques for hydroponic tomato production in Navarra, northern Spain, related to the crop water requirements. The results show that although daily over-irrigation was applied (45.7% of drainage), 18% of the total yield (35 kg m−2 ) was affected by blossom-end rot problems, due to water stress suffered by the crop. Irrigation scheduling by time clock was not flexible enough to satisfy the varying crop water requirements through the day and during the season. With constant irrigation intervals and volumes, water and fertilisers were wasted during the morning (excessive irrigation) whereas during the afternoon, the plants suffered water stress. Irrigation scheduling by radiation method at a level of 0.81 MJ m−2 , with some supplementary time clock irrigation applications during the hours of darkness (in order to keep the growing medium wet), appeared to be a good solution.

Hydroponics means “water working.” Therefore, a true hydroponic culture is one that uses water only, with plant nutrients added in the correct concentrations and ratios for the plants grown. In most cases, hydroponic culture involves a substrate for the plant roots to grow in, and is consequently termed “soilless culture.” Hydroponics goes back as far as the famous hanging gardens of Babylon and the floating gardens of the Aztecs. From the early 1600s until the 1800s, “nutriculture” techniques were developed for the growing of plants in laboratories to study plant nutrition. Dr. William F. Gericke of the University of California coined the term “hydroponics” in the early 1930s, as he developed techniques to commer- cially produce crops without soil. His first practical application of hydroponics was during World War II in an effort to grow fresh vegetables on non-arable islands where troops were stationed. Installations were established on Ascension Island in the South Atlantic, Iwo Jima and Okinawa in the South Pacific, and later, on Wake Island and a 22-hectare (55-acre) project at Chofu, Japan after the war. The U.S. Army, with its own special hydroponics branch, grew over 8,000,000 pounds of fresh produce during 1952. Today, there are about 2500 acres of greenhouse hydroponic vegetables produced in Canada, and over 1500 acres in the U.S. Principal crops grown are tomatoes, cucumbers, peppers, eggplants and lettuce.

A New Method for Hydroponic Tomato Production - ResearchGate

wood or soft-wood cuttings. The main difference between them (apart from the obvious colour of the fruit), is that black currants fruit on one-year old wood, while red (and white) currants fruit on spurs, which develop on older wood. In fact, white currant is an albino form of the red currant. Because of the differences in fruiting habit, production systems will differ markedly, with the objective of the red (white) currant being to establish a strong framework, while with the black currant the need is to develop new growth annually on which the fruit will be produced the following year. Clearly, growing plants year-round in a greenhouse is desirable to growing outside for a part of the year, although there will be a need to make the plants dormant and provide a means of winter chill, either naturally or else by means of a cold store. This suggests that growing the plants in pots (or modules ) of a good growing medium will be essential. Cocopeat (coir) is likely to be an excellent growing medium, provided a full hydroponic solution is used. Obviously, bees will be required to provide pollination, but this should not be a major problem (except in Australia) where bumblebees are prohibited.

greenhouse vegetables Hydroponic Tomatoes Maximizing yields from hydroponic tomato crops has long been the main objective of commercial growers. However, there’s growing consumer pressure to produce high-quality, great-tasting fruit that stores and handles well in the retail sector.

GPN will bring you a few articles a year, but if you want in-depth information year-round, research such as this can be found in The Growing Edge magazine. It is a great resource for hydroponic growers.

Obtaining economic yields of highquality fruit while minimizing the use of pesticides and other agrichemicals has put commercial tomato growers under increasing pressure, and many are now looking to modified hydroponic systems where higher profits are possible. Many of these new tomato-growing techniques involve the production of “spray-free” crops and using organically based systems. Today’s selection includes a wide range of new, fresh tomato products, such as lowacid fruit; on-the-truss, cluster or vine-ripened fruit; and many new....
