Hydroponics is the practice of growing plants in water without soil, and with the proper nutrients added. This process became considerable popular in recent years, and has been done experimentally for over a century.  You can see many examples of natural hydroponics by looking around streams and creeks. Hydroponics has come a long way since the Aztecs and the Babylonians. It has become an important method of producing crops in various countries in the modern times.

In most hydroponic systems grow trays come equipped with top of the line tub outlet drain fitting, allowing users to install a stand-off to adjust the solution level in the tray. The hydroponics system is equipped with a drain to handle high volumes of water.

The hydroponic system includes a channel-like trough formed of extruded plastic, the trough having parallel side walls and an orthogonal bottom wall defining an upwardly opening coffer. A pair of oblique walls extend integrally from a medial portion of the bottom wall to a respective medial portion of the side walls to define a V-shaped bottom in the interior of the trough.

The hydroponic system you set up is going to be on a strict watering schedule that is set by you, and which you must follow rigorously for the good of your plants. This will prevent your plants from getting too little or too much water.

The hydroponic system in my house is set up in a walk-in incubator in which the temperature was kept at 25 degrees C. Eight polycarbonate hydroponic trays (27 cm long by 21 cm wide by 14 cm deep), each designed to hold 12 plants, were used.

The hydroponic system mainly consists of culture containers and mineral wool slabs. The hydroponic system is used within a controlled-environment room (CER) for control of the aerial environment. The growing shed/incubator is equipped with an auto calibrating system for atmospheric CO2 control.

Plants grown in soil-free gardens have the perfect balance of nutrients and water delivered directly to their roots when the best nutrient feed products are used. Crops are not forced to expand their limited energy searching for water and food. Plants in the famous, NASA originated, aeroponic system showed increased vegetative growth, delayed tuber formation and an extended vegetative cycle of about seven months after transplanting.

Plants grown in pots usually hit growth plateaus when they become root-bound, requiring messy and difficult transplanting. A properly designed hydroponic system can avoid this and many other problems commonly found with soil pests are simply non-existent. However, Both hydroponic and soil-grown plants need 16 elements in order to grow. The top three elements, known as macronutrients, include nitrogen, phosphorous, and potassium. Three other elements essential to plant growth, known as secondary nutrients, are calcium, sulfur, and magnesium. The remaining nutrients are called micronutrients. All sixteen of these nutrients are vital to any growing system. In any good hydroponic system, the plant receives all these elements in its water.

Plants thrive even with such a small root volume because just the right amount of water containing a soluble fertilizer is continually dripped into the medium. Plants require light in order to photosynthesize, so if your hydroponic garden is an indoor garden then you may consider using artificial light. A regular light bulb will not be any good in this situation.
