History reveals that the Hanging Gardens of Babylon is a big evidence of a hydroponic garden. Moreover, the Aztec Indians in the now Mexico had a system of growing crops on rafts. These rafts are in shallow lakes that you can still see in floating gardens near Mexico City. Therefore, history shows the great significance of hydroponic system of growing plants even in ancient times.

Developments with hydroponics did not however take place in Europe until 1699 when Woodward discovered it. He found out that he can grow plants in a solution of water to which soil had been added.

On the other hand, Liebig, a German scientist, originated using nutrient solutions to study the nutritional requirements of plants in the 1850′s. It was then followed by Sachs in 1860. Knop also did some studies of nutrient elements in water solutions in 1861. They grew plants in nutrients-rich solutions with mineral salts. This does away with the soil as a main requirement for growing crops.

Many researches on the nutritional requirements of plants extended through even until the 1870′s. By 1925, practical applications of hydroponics were being introduced for the vast development in the greenhouse industry.

If you’re into hydroponic gardening, you might want to think about purchasing or building a greenhouse. Many people start off with some sort of homemade hydroponics setup in their basement or spare room. However, it’s a lot easier to manage all the conditions necessary for a thriving garden if it’s located in a greenhouse. It’s a lot easier to manage lighting conditions, air movement and temperature.

Growing your hydroponic garden indoors just isn’t as ideal as using a greenhouse. A hydroponic greenhouse allows for better lighting and watering system setup. There aren’t too many people who want to let their hydroponic garden take over the house.

The grow lights and irrigation systems required for successful hydroponics can be very space consuming. With a greenhouse these systems can be placed exactly where you need them. This is important in hydroponics, because regulation of water and light are more essential than in a regular garden.

One of the most important advantages of growing your hydroponic garden in a greenhouse is the ability to control the light. In order to flourish, plants that are grown hydroponically require plenty of light. At the same time, it’s important they don’t get too much direct sunlight since it will lead to excessive algae buildup.

In modern history, hydroponics has only been around since about the 1930s. It is a relatively new technology, and has grown rapidly since its inception 70 years ago. It began first as an academic exercise and soon grew to be embraced by industry and government.

Hydroponics has found many new applications. It is a very versatile technology, and has a very beneficial use in developing countries as well as high technology space stations. Hydroponic technology can efficiently grow vegetable crops in what was previously unthinkable – from barren desert sand to desalinated ocean water. It thrives in mountainous regions too steep to farm, on rooftops, in small yards and in arctic communities. In areas with high populations where land is expensive, hydroponics can providehigh-value specialty crops such as fresh salad greens, herbs and cut flowers.

Agriculture tends to migrate toward higher-technology solutions and more capital-intensive solutions to problems. Hydroponics is highly productive and suitable for automation. However, the future growth of hydroponics depends greatly on the development of systems of production that are cost-effective with those of common agriculture. Many improvements in these technologies such as lighting and plastics, and new cultivars with better pest resistance and disease resistance will yield increased crops yields and reduce costs. Hydroponic greenhouses which can use the ‘waste’ heat from industry could expand in the next few years. Geothermal heat could support large areas of greenhouses in the right locations.
