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 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.

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.
