Hydroponic systems feed the plant directly with the nutrients that a plant would get out of the earth, while at the same time allowing for a virtual reduced or pest free environment. The plant uses less energy since the nutrients are dissolved into the water that is directly fed to the plants. It uses only about a tenth of the water that traditional soil growing uses. There is a greater ability to keep the food safe and free from condemnations that the produce would be subjected to in a field.
There can be a year around production with harvests occurring indoors with a predictable yield with the outside climate extremes having no bearing on the production or quality of the produce.
