Moving water from the water reservoir to the plant by means of a wick. Similar to the way oil is drawn up the wick in a lamp, the water is moved close to a plant's roots for absorption.<br /><br />

− | '''[[w:Deep_water_culture|Deep Water Culture]]''': Consists of a water reservoir, containers with which the plants are suspended into the water and a way to keep them on the surface, and an air pump and air stone. The plants are suspended in such a way that the roots sit directly in the water. The air stone is put in the water under the plants to aerate the water to ensure that the plants don't suffocate or drown. This is one of the most common system setups.

Consists of a water reservoir, a pump and a separate growing tray for the plants. The water is pumped from the tank to the tray which is sloped to cause the water to flow from one end to the other to water the plants. When the water reaches the other end, it flows back into the reservoir.

The plants are not constantly exposed to water in this system, but at certain times per day, the roots are flooded for a certain period of time, then drained. This can be done manually by filling it by hand, or by pump, or even more advanced by attaching the pump to a timer.

The pump pumps water from the reservoir through the tubing to drip into the individual plant containers. The water that seeps out of the bottom is collected in the tray and returned to the reservoir. This system is most common commercially as the set-up cost is a bit higher than many of the other models and requires a little more maintenance.

− | A medium, in this case, is a non-soil substance in which the plants grow but receive no or minimum nutrients from. The purpose of this is to keep the plants in an upright position and to allow water and/or fish waste to become trapped around the plants roots for absorption. Examples of these are gravel, sand, coconut coir, wood chips, clay balls, or Perlite.

− | Hydroponic and aquaponic systems both produce much higher yields in comparison to more common farming, such as large scale outdoor farming.

− | Hydroponics:
| |
− | In many commercial growing settings, the plants do not have strong immune systems since they have not been exposed to the outdoor life which would harden them against diseases. This is in contrast to aquaponics which has a bit more exposure due to the fish and the bacteria associated with them. Many commercial hydroponic systems require a near sterile environment because of this. Diseases include powdery mildew, root rot, rust, botrytis, among many others.

− | Powdery Mildew: Develops when standing water is allowed prolonged contact with the plant in areas other than its roots. Prevention involves avoiding allowing this water from pooling on or around the stems and leaves of the plants. Fungicides and other treatments are available that will help to curb this problem.

− | Tomato Spotted Wilt Virus: It looks just like the name suggests. There is not a treatment for it, so removing a plant that looks odd is key before it can spread. The produce will ripen oddly and the skin of the plant's fruit will develop odd welts. Not a good sign.
| |
− | Deficiencies: In an aquaponics system, this may be caused because the fish may compete with the plants for a certain nutrient. Also, pH can cause damages as well. Taking water tests for serious growers and keeping the water moving and clean for less experienced growers will help to solve this problem.

| |
− | Insect Infestation: These can be a major cause of concern as the plants are inside, unexposed to a number of animals that would keep the plants free of the pests. In a hydroponics system, manually removing the insects or using insecticides are recommended. Since insecticides cannot be used in aquaponics, manually removing the insects is good, but removing the plant and letting it soak completely in the fish's water for a while will cause the insects to let go. A great source of food for the fish!

There may be reasons that the plant is not doing well, especially if the other plants are thriving. If all the plants are sickly, that is a sign that either the entire system is infected, or there is a deficiency. Of course, this is assuming that water and light, humidity, and the other basic elements of plant survival are adequate.
