The word hydroponics comes from the word Hydro which means water and ponos which means labor. Throughout history there have been many different forms and revisions made to general hydroponic usages. With so many different methods of hydroponics it's no wonder that the science of hydroponics has grown and flourished especially with food science and plant sciences and their recent breakthroughs.

General hydroponics has taken some great leaps and bounds throughout the last century. With one of the first great breakthroughs in hydroponics which was used during World War II. In World War II troops which were stationed on islands which were unable to grow most fresh produce, began to use a scientifically proven form of hydroponics system in order to locally grow fresh produce to help feed their battalions and enjoy a balanced diet will still stationed in an area that could not grow plants using traditional methods.

Towards the end of the century General hydroponics began to take on an entirely new focus with relation to the space program. NASA's original focus with hydroponics was to see if it was possible to grow plants in space as well as potentially create large-scale greenhouses and settlements on other planets such as the moon. Hydroponic research with NASA is ongoing and especially with the new Mars projects NASA is always looking for newer and more efficient ways to grow plants in low gravity as well as in space for longer space missions. Any advancement in General Hydroponics in space or in a low gravity environment could lead to a longer spaceflight mission or a better possibility of extended trips on mars or in space. Today there are even hydroponics sections on the international space station and food can be grown for experimental purposes and to feed astronauts in space.

Around the 1970's not only NASA but many others began to really advance hydroponic research. Many farmers began to use a hydroponic technique because of the control that they could take on over their crops. Growing with hydroponics usually results in more consistent results because sunlight can be on 24 hours a day in the beginning stages of growth and adjusted for better growth and flowering of plants later on in the life span of a plant. Many scientists and any lists have studied hydroponics and begun to look into new soil types and better forms of grow lights to make hydroponics more efficient and more effective for growth yields than ever before.

The great part about using hydroponics is that plants can grow in areas all around the world and at a higher yield because of the types of soil used. Hydroponics also eliminate the need for pesticides by controlling the soil and closing off the environment that plants are in. The food is cleaner, larger and healthier than it has ever been because of hydroponics. By controlling each part of the growth stage of the food, from air, light, soil and fertilizer, a good farmer who is familiar with general hydroponics can now produce a better quality product than ever thought possible.
