A big advantage of these hydroponic growing systems is that they allow gardeners to grow tomatoes anywhere from cold climates to arid deserts to temperate zones. This is because hydroponic systems are usually incorporated into greenhouses.
However, a key disadvantage to the system is pests. It may be assumed that hydroponic systems would reduce the amount of pests and insects by being enclosed, as in a greenhouse, but this enclosure also encourages pests by shutting out their natural predators. Some frequent species of pests that can pose a problem in hydroponic systems include whiteflies, tomato fruit worms, tomato pinworms, leaf miners, cabbage loopers and two-spotted spider mites. A potential way to ward these off is by introducing their natural predators to the environment.
