  Most vegetables can be grown hydroponically. The exception to this is root vegetables, such as potatoes, carrots, radishes, rhubarb and onions, because they need more of a soil medium to keep the fruit of the plant from rotting.Root vegetables can grow in a hydroponics system, but they will not produce as well. The more popular vegetables to grow hydroponically are: tomatoes, cucumbers, spinach, lettuces, artichokes, beans, cabbage, corn, eggplant and endive, just to name a few. Leafy vegetable plants grow best, but tomatoes and cucumbers are the more popular to grow. Hydroponic vegetable growing is becoming more popular, because the plants produce for a longer period, in some cases tomatoes can produce for up to a year.

  The list of flowers that can grow in a hydroponics system is almost endless. Growing hydroponic flowers, like any other plant, will depend on your space.

A few flowers that thrive in a hydroponics system are: amaryllis, dahlias, chrysanthemums, iris, freesia, lily, gerbera and orchids to name only a few. Orchids are one of the most popular flower to grow in this system, because it keeps the constant moisture levels of the plants at an optimum level, and gives the flower the humidity needed to thrive.
