Hydroponics is a method of growing plants without soil by giving all the nutrition plants need through a nutrient-rich solution that can be supplied to plants in different ways depending on the type of hydroponics system being used.
The nutrient solution is made up of different plant supplements, nutrients, and fertilizers dissolved in water that is then given to the plants. To know about hydroponics equipment you can visit https://hydroshop.co.za/18-hydroponic-components

The most productive hydroponics systems that have large yields are the ones that completely control as many factors as needed for plant growth as possible.
The most distinguishing aspect of hydroponics systems is that they do not need soil in order to grow plants. The soil has two main purposes in soil-based gardening it holds and supports the plants and their roots, and also acts as a buffer for nutrients, pH, fertilizers, etc. and holds them longer than hydroponic grow mediums which makes it more forgiving to grow in soil versus hydroponics.
Again, this is why it's important to properly control as many inputs as possible when gardening with hydroponics. If done properly, higher yields can be achieved with hydroponics compared to soil, but it requires effort and attention.
There are many options to choose from when deciding which hydroponics system to use. The most common systems are deep water culture (DWC), ebb and flow, and drip watering systems, although there are more advanced systems as well.
In DWC hydroponics systems, the plant roots are placed directly into the nutrient solution. The nutrient solution is oxygenated by placing air stones at the bottom of the reservoirs.
