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.
When growing herbs in a hydroponics system, keep in mind they are slower growing, but once mature they will produce a larger harvest of aromatic herbs for your cooking.

Marjoram, mint, rosemary, chives, thyme, sage and oregano are a few of the other herbs which can be grown in a hydroponics system.
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. Larger or taller flowers like rose bushes, or gladiolus will require more space to prevent over crowding.

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.
Like vegetables, the growing season of fruits can be greatly extended when grown in a hydroponics system. Berries, such as: strawberries, raspberries, blueberries, black berries, boysenberries and loganberries are the most popular fruit grown this way. Other fruits, such as: bananas, papayas, pepinos and currants are a few other fruits that can be grown in a hydroponics system.
