In the simplest terms, hydroponics is growing plants without soil. In the 19th century, it was discovered that soil is not essential for plant growth, as long as nutrients are present in the water supply. Since this discovery, hydroponic growing has evolved into different types, with many benefits over traditional soil-based cultivation. What are the general benefits of hydroponic growing? Hydroponic production has many advantages, including: Larger, higher quality crops due to controlled nutrient ratios No soil-borne diseases passed among crops Up to 90% less water is required compared to growing in soil High yields in minimal growing space Can be used in areas where soil-based cultivation isn't possible, such as locations with poor soil quality, or where water supplies are limited No herbicides necessary because there are no weeds
