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.

Dripping systems also need some attention during maintenance check ups. Always have a few extra drippers on reserve incase there are circumstances which call for replacements. For examples, clogged drippers should be replaced immediately. To clean the clogged dripper, dip it into a vinegar solution and scrub if necessary. If the dripper is far to clogged, consider soaking it in water prior to the vinegar solution. Keep drippers nearby so they can be used as replacements whenever needed.

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.
