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.

Trail and error is the universal method towards improvement. A good way to improve is to keep a journal which monitors certain aspects of the hydroponic setup. Things to jot down would be the daily EC and PH levels, how often proper maintenance is preformed, what type of pH changers were being used, and of course how successful the plants grew. Combine new solutions to past mistakes as well as already established positive factors to improve your harvests.
