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.

When growing plants with a hydroponic setup, maintaining the system is very important. Proper maintenance will ensure that high yields and nutrition high foods will remain constant. Simple routine clean ups will prevent any problems from rising in the future. In any type of gardening, any pests which exist in the growing environment do nothing but leech nutrients from plants. Following this concept, remove any dead and dying leaves from plants.

Before introducing a plant in the previous diseased area, clean up any residue left behind. Diseased Plants should be removed and its area should be cleaned thoroughly with a bleach solution. Before changing any water in the tank, wash it out with a cleaning solution. Remove any residue, and make sure areas which hosted a diseased plant are cleaned properly.
