Hydroponic gardening may sound like a futuristic idea but it is not. It is part of hydroculture, the practice of growing plants only using water with a growing medium and nutrients. There is no soil involved.
With the technology available today, we can grow our favorite plants, or any plant for that matter, at any time of the year. With the latest hydroponic systems along with specialized horticultural lighting, indoor gardening becomes easy and effective. If plants receive the water and nutrients they need at their roots, they can grow exceedingly well without soil. When these plants are food, they can feed the world by producing more and better quality plants than soil-based farming can produce.
