A plant can be stressed when it desires nutrients but can not get any. With hydroponic techniques, plants are never stressed. Air, nutrients, and sunlight are always available to the plants with a hydroponic setup. Sunlight is readily available when the garden is located outdoors; however, when a garden is indoors artificial lights can be set up to simulate natural sunlight. Sufficient air circulation needs to be setup for indoor setups as well or the roots may die. With a good air circulation setup, the air may also prevent any disease which may be caused by conditions which are too moist.

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.

Though the idea seems rather unpractical, its results prove that it may well be the future of gardening as we know it. It uses very advanced techniques and utilizes the understanding of essential chemicals needed for high yields and faster growth. Although it uses only water and no soil to grow, hydroponics really uses less water per yield then regular soil growing.
