There is no need for weeding and the worry of pests or soil borne diseases is drastically reduced. Hydroponics is always a soil less culture, but not all soil less cultures are considered to be hydroponics. Many of these cultures do not use the nutrient solutions, which are required for hydroponics. There are two main types of hydroponics, which are solution culture and medium culture. Environmental control systems were being developed to help growers provide the ideal plant environment in addition to the ideal plant diet. Commercial crop growers are turning to soil less cultivation more and more. The speed of growth combined with the control over the growing environment means higher quality crops. Hydroponics is proven to have several advantages over regular soil gardening. The growth rate on a hydroponic plant is 30 to 50% faster than a soil plant that was grown under the same conditions. The yield of the plant is also greater. There are many reasons for the drastic differences between hydroponic and soil plants. Plants are able to change their own cellular pH level to stop or help speed up a certain enzyme reaction. The electrical charges in soil particles are different from those in mixtures with no soil. Because of this reason, different pH levels for nutrient uptake are needed for each type of growing medium. The nutrient mixture is the right one for the plant, in the right ratios, every time. The fear of soil-based diseases is eliminated, because, of course, there is no soil. These two factors come together to make hydroponics an extremely efficient method of food production. Hydroponics is also environmentally sound. The hydroponic systems also require less space, because the plant roots don’t have to spread and search for food and water. The small space requirement makes hydroponics perfect for limited space home gardeners. The greatest benefit to hydroponics is the ability to automate the hydroponics system with timers and remote monitoring equipment.
