Water is always surrounding the plant roots in a hydroponic setup. Because water and nutrients are always present, it allows plants to grow faster and stronger. Plants can be harvested early which can result in more plants being planted per season. Another advantage of having water always present is that it minimizes the space needed to garden. Plant roots no longer have to spread out to search for nutrients as it always in reach. Since the roots do not have to stretch outwards, the nutrients which should be allocated to that task can be used in growing. Though hydroponic gardening has its advantages, it has restrictions on plant requirements.

The nutrient concentration of a hydroponic garden is often referred to as the EC level. If your hydroponic garden consists of Grodan plants, they would require less fertilizer then what they would need in a soil based garden. This is because of the technical system of hydroponic gardens. In soil gardens the nutrients in fertilizers are not all absorbed by the plants, because the soil acts like a buffer. In a hydroponic set up, there is nothing acting as a buffer, and all the nutrients from fertilizers are easily absorbed by the plants. It is a general rule that EC and pH should never be lower then 5 and higher then 7, as the plant would not be able to absorb any nutrients.

Before introducing a plant in the previous diseased area, clean up any residue left behind. Diseased Plants should be removed and its area should be cleaned thoroughly with a bleach solution. Before changing any water in the tank, wash it out with a cleaning solution. Remove any residue, and make sure areas which hosted a diseased plant are cleaned properly.
