The processes known collectively as hydroponics are those which look to grow plants or crops, but in a very unique, new and innovative way. Instead of using soil as the substance which provides nutrients, minerals and water for the plants the grow, this is replaced by a solute rich stream of water, that is normally sent to flow around a number of plants at the same time. In fact, hydroponics as a wider area is simply the process of growing a plant without the use of soil. Using a hydroponic shop for supplies is vital.
By changing the growth medium from soil, to something of the growers choice, lets say a flow of water, it is easier to control the nutrition that the plant gets. The user can give the crops exactly what they need and this is a much more controllable process than using soil a the medium, where there are potentially a lot more unknowns for the grower to encounter. In the UK, there is a potential for hydroponic growth because the crops can normally be grown in a much more confined region, UK hydroponics can therefore save on vital garden space that so many people in the UK have a lack of, because it is so densely populated.
In addition, UK hydroponics can mean that more exotic plants can be grown in the country, some of which simply would not be possible if grown in the conventional manner with soil as the growth medium. It can also mean that less water in total is used and plants can grow a lot quicker.
Hydroponics can potentially save on things like water cost and space in the long run, but such projects are typically much more expensive to set up than conventional plant growth.
