Plants
You can grow just about anything hydroponically that you can when using traditional techniques. Chances are, your favorite plants will thrive in their new conditions. Basil, beans, broccoli, Brussels sprouts, cabbage, cantaloupe, carrots, cauliflower, chilies, chives, cucumbers, eggplant, lettuce (and various other salad greens), mint, peppers, radishes, spinach, strawberries, tomatoes, and watermelon are all common hydroponic crops. Certain growing systems and conditions work better together with some crops. It is a good idea to do some research to find out what will work best for your situation.
Hydroponic plants can be started just like traditional plants. They can be grown from seed in germinating medium and then transplanted. Remember that the plant's roots need to be cleaned before transplanting to a hydroponic system. This is especially important if a plant is ever going from a soil-based situation to hydroponics. Seeds can also be sown directly in rockwool starter cubes that can then be transferred to a growing system. Many plants can also be started from cuttings. For more information on starting plants from seed, see germination; for more information on starting plants from cuttings, see propagation.
