Soil-based agriculture is currently facing challenges as a result of several man-made elements such as industrialization and urbanization. Furthermore, unforeseeable natural disasters, climate change, and unchecked chemical use in agriculture impair soil fertility and quality. As a result, scientists have developed a completely new alternative form of growing known as hydroponics, commonly known as soilless agriculture. Plants can be cultivated hydroponically by immersing them in a nutrient-rich water solution. Hydroponics can be used to cultivate a wide range of plants, crops, and vegetables. In general, hydroponically grown produce outperforms soil-grown produce in terms of nutritional value, flavour, and yield quality. This agricultural practice is gaining popularity in both developed and developing countries throughout the world. Along with sophisticated space research, it has the ability to fill the void left by a lack of adequate cultivable land in many countries. As a result, hydroponics would be a superior technique to producing numerous fruits, vegetables, and livestock feed, as well as meeting future global nutrition requirements. In the future, hydroponics may emerge as a new method of feeding the world's population.
