What is hydroponics?
Hydroponics is a form of gardening and method of cultivating plants using no soil. Soils can hold all sorts of plant damaging infections and diseases and researchers wanted to find ways to minimize the exposure of the plant to to these plant health problems. Hydroponics is one such way wherein the plants grow but do not use soil for establishing their roots.
Soil Is Not Important
From studies of hydroponic gardening, researchers have established that the soil is actually just a reservoir where nutrients are stored for the plant's consumption. The medium the roots grow in is simply there to store the plant's food and to provide support for the roots. Therefore, this reservoir is not essential if the plant can get the nutrients some other way and the plant can be supported by other means. Hydroponics research has found out that the nutrients in the soil dissolve when they come in contact with water, this makes it a lot easier for the plants to absorb them. Hydroponics has done away with the need for soil for some plants.
Plants that are usually found in soil, can actually survive even when they are soilless, as long as they have access to the right kinds of nutrients that are essential to their growth. Hydroponics can also use some mediums that may be less problematic for a healthy human life. Mediums such as mineral wool, perlite and gravel can work very well since all they need to do is provide the roots with something to hold on to for stability.
The important factor in hydroponics is actually the mineral solution that fills the nutritional needs of the plant. Most plants can grow without soil just so long as the nutrient based solution is present. The solution is actually formulated to meet the demands of a thriving and growing plant and given to the plant in doses. Not all plants can tolerate their roots being exposed to water all the time so some nutritional solutions are supplied as a drip feed and given at certain intervals.
Some of the benefits of using hydroponics for growing plants such as cultivation in a clean environment allow the growth of much healthier and stronger plants. The absence of many of the common diseases that target plants and produce allows the plants to grow faster and stronger than they would otherwise. Hydroponics also provides a solution to growing food and plants in barren places such as deserts and rocky areas. Soil is not as important as we always thought and we can grow most plants in greenhouses that have nutrients directly provided for the plants without the problems of soil types.
