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 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.

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.
