In the simplest of words, hydroponic growth is a method of growing plants where the soil is not involved and water is the key element here. The roots of the plants are in direct contact with water or are surrounded by a non-soil medium such as stonewool or coco coir which allows a lot of access to water. Here, the growth is faster and better compared to soil-based growth because the plants can get direct access to water and nutrients without the roots having to look up for them. There are a number of different ways in which hydroponic systems can be set up, but the common factor among all of them is that this is primarily a water-based method of growth.
