Put simply: Hydroponics is a way to skip the soil, there are many variations when mentioning Hydroponics. Plants grown in hydroponics have roots that are submerged in an inorganic growing medium whilst nutrient rich water is applied directly to the roots of the plant.
How does a plant survive and thrive without soil?
As for hydroponics the roots are submerged in an inorganic growing medium like rock wool or clay pebbles, leaving the nutrient demand up to the nutrient rich water that is applied to the plants roots. There are numerous types of hydroponics systems, some include Nutrient Film Technique (NFT), Ebb & Flow, Drip Systems or Deep Water Culture (DWC).
Why Grow Without Soil?
Some advantages of hydroponics is that the grower is able to grow anywhere, at anytime of the year and to net higher yields with fewer resources.
Growing seasons and regions are in major flux due to global temperature changes. Even in “normal” conditions, the ground in certain regions is not conducive to farming. Hydroponics allows growers to grow ANYWHERE ANYTIME!
Since roots are bathed in all the nutrients they need, plants spend more time growing upward and less time growing root systems to search for food. Growth rates vary based on the type of system and quality of care, but hydro plants can mature up to 25 percent more quickly than the same plants grown in soil.
Fewer Resources `
Hydroponic systems use less water than traditional soil-based systems. Water used in hydroponic systems can be filtered, re-populated with nutrients, and fed back to plants again so that water is constantly being recycled. Hydroponics also avoids other harmful resources such as Pesticides.
With a hydroponic system, you know exactly what conditions your plants are being grown in. As such, you can easily isolate variables, plants can be supplied with the optimal conditions for growth whilst ensuring soil borne pests and weeds are eliminated.
