There are currently projections of water shortages in certain areas. This projection has led to the growth of hydroponics gardening as it uses less water then soil growing and also has better nutrition value. Hydroponic gardens take up less space which makes them more versatile. They can be grown in basements, apartment balconies and much more. Since there is no soil used, hydroponic gardens do not inhibit soil type bacteria, diseases, pests, and unwanted plants that leach nutrients. The absence of soil enables the possible of erecting hydroponic gardens anywhere, even sandy or dry areas do not restrict hydroponic gardens.

The tank solution should be routinely changed once every week; it should be a entire change of solution. It is possible to adjust the EC and pH with additives however it is cleaner to do a full change. This is because the solution may lack micro nutrients or it may also be infected with root rot also known as Phytium. In cases where there is a ready to use nutrient solution, to lower pH use lemon juice or any other phosphoric acid. In cases where there is a injector ready, use a sulphuric acid to lower the pH.

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.
