    Thumbs up What is Hydroponics?

    Hydroponics literally means "water working" in Latin. Hydroponics is the practice of growing plants in either a bath or flow of highly oxygenated, nutrient enriched water.

    In soil, biological decomposition breaks down organic matter into the basic nutrient salts that plants feed on. Water dissolves these salts and allows uptake by the roots. For a plant to receive a well balanced diet, everything in the soil must be in perfect balance. Rarely, if ever, can you find such ideal conditions in soil due to the lack of organic matter left behind on the surface, contamination and biological imbalances.

    With hydroponics, water is enriched with these very same nutrient salts, creating a hydroponic nutrient solution that is perfectly balanced. And since this hydroponic nutrient solution is contained, it does not harm our environment as does runoff from fertilized soil. Additionally, very little water is lost to evaporation in a hydroponic system, owing to its application in drought stricken areas.

    To support the plants in a hydroponic system, an inert soil-free medium like fiber, sand or stone, may be used to anchor the roots. These hydroponic mediums are designed to be very porous for excellent retention of air and water that's necessary for a healthy plant - roots need to breathe too!
    In addition to a perfectly balanced diet, hydroponic plants have their food and water delivered directly to their roots. This way, the energy normally used to develop long roots can be redirected to growing more plant, which is a great benefit indeed! With the proper exposure to natural sunlight or supplemental grow lights, your hydroponic plants.

    Nice

    Yes very much right. You can say it is also just opposite of organic grow.

    Nice post! It actually covers all areas that make hydroponics an amazing gardening method. I, personally love the idea of growing with hydroponics because it lets even novice growers like me to have the best opportunities to produce the finest crops with less hassles and less worries. Another great thing about it is that there is no dirt or pest to deal with. Great!

    A technique of growing plants (without soil) containing dissolved in water nutrients.When most people think of hydroponics, they think of their planting and plant roots suspended directly into the water, no plant material.

    or as already stated ,oxygenated nutient rich water flushing over an inert medium.
    if you're retired or you ain't got a job and you ain't growing and smoking weed ,i don't know what the fuck you are doing!

    Hydroponics is simply means the plant in water. Plants placed in the growth medium, such as rockwool, clay pellets, foam, recycled foam, gravel, peat, sawdust, or coconut, is fed to the nutrient solution, so that they grow. Since many hydroponic methods employ some type of substrate, these methods are often termed "soilless culture",while water culture alone is true hydroponics.

    History of Hydroponics


    The History of Hydroponics

    As seen in Growing Edge Magazine

    Hydroponics basically means working water ("hydro" means "water" and "ponos" means "labor"). Many different civilizations have utilized hydroponic growing techniques throughout history. As noted in Hydroponic Food Production (Fifth Edition, Woodbridge Press, 1997, page 23) by Howard M. Resh: "The hanging gardens of Babylon, the floating gardens of the Aztecs of Mexico and those of the Chinese are examples of 'Hydroponic' culture. Egyptian hieroglyphic records dating back several hundred years B.C. describe the growing of plants in water." Hydroponics is hardly a new method of growing plants. However, giant strides have been made over the years in this innovative area of agriculture.

    Throughout the last century, scientists and horticulturists experimented with different methods of hydroponics. One of the potential applications of hydroponics that drove research was for growing fresh produce in nonarable areas of the world. It is a simple fact that some people cannot grow in the soil in their area (if there is even any soil at all). This application of hydroponics was tested during World War II. Troops stationed on nonarable islands in the Pacific were supplied with fresh produce grown in locally established hydroponic systems.

    Later in the century, hydroponics was integrated into the space program. As NASA considered the practicalities of locating a society on another plant or the Earth's moon, hydroponics easily fit into their sustainability plans. This research is ongoing. But by the 1970s, it wasn't just scientists and analysts who were involved in hydroponics. Traditional farmers and eager hobbyists began to be attracted to the virtues of hydroponic growing.

    A few of the positive aspects of hydroponics include:

    The ability to produce higher yields than traditional, soil-based agriculture
    Allowing food to be grown and consumed in areas of the world that cannot support crops in the soil
    Eliminating the need for massive pesticide use (considering most pests live in the soil), effectively making our air, water, soil, and food cleaner
    Commercial growers are flocking to hydroponics like never before. The ideals surrounding these growing techniques touch on subjects that most people care about, such as helping end world hunger and making the world cleaner. In addition to the extensive research that is going on, everyday people from all over the world have been building (or purchasing) their own systems to grow great-tasting, fresh food for their family and friends. Educators are realizing the amazing applications that hydroponics can have in the classroom. And ambitious individuals are striving to make their dreams come true by making their living in their backyard greenhouse, selling their produce to local markets and restaurants. And now that so many people from so many different walks of life are involved in hydroponics and its associated disciplines (such as aeroponics and aquaponics), progress is coming faster than ever before.
