An increase in land distress, food requirements, and greenhouse emissions, are some of the innumerable problems dealt with by conventional farming. The use of pesticides and chemical fertilizers often leaves consumers looking for organic and safer produce. Hydroponics can be the solution to these problems with its potential to enhance and maximize the use of water, nutrients, and space. Furthermore, it also provides superior control over the environment and plant protection aspects. Hydroponics technology is arguably the most diverse technique for producing crops currently. Hydroponic is an effective way to grow crops in ecosystems with harsh natural conditions, such as deserts, mountainous areas, or arctic settlements. Hydroponics cultivation improves crop quality and productivity, leading to a higher economic outcome. This paper reviews hydroponics as a whole. The types of systems that can be implemented, are based on factors like structure and techniques, and the factors affecting them. This paper further analyses the production of various crops and compares it to conventional farming methods. Hydroponic systems produce a yield much better than traditional methods. With a wide variety of techniques available, hydroponics can be customized based on the type of crop grown.
