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 most important factor in any type of gardening is having enough nutrients available. In soil based gardens, there is never sufficient nutrient, which is why fertilizers are used in every soil garden. Hydroponic gardens operate a little differently; they use a specialized type of fertilizer which is customized to be efficient in hydroponics. Using hydroponic fertilizers are more difficult to use compared to soil fertilizers. Be sure to read the instructions carefully, the hydroponic fertilizers usually require a certain Ph and dilution level.
