Hydroponic gardening is easy and fun once the concept and principles are understood.
There are a few basic rules that must be followed to make a good hydroponic system productive. First, let's look at how and why hydroponics works. In the basic hydroponic system, the inert soilless medium contains essentially no nutrients of its own. This solution passes over the roots or floods around them at regular intervals, later draining off. The extra oxygen around the roots is able to speed the plants' uptake of nutrients.
