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. Remember that over time the water being used will slowly evaporate. As it does the concentration of fertilizer will increase and may cause burns on the plants. To avoid this, you should monitor your water levels and add water accordingly.

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.
