Hydroponic gardening involves growing plants in nutrient-filled water so the plants can devote more energy to producing fruits and vegetables rather than searching for food. The process involves no soil but may include another material such as gravel that plants’ roots will grow through. This method of gardening provides an ideal nutrient balance for plants, producing nutritious, abundant crops. Furthermore, hydroponics reduces or eliminates pests, reduces time spent gardening, and makes it easier to grow plants in arid regions. Most vegetables and a number of fruits will thrive in this system.
