Hydroponics: How t grow indoor hydroponic vegetables

What is hydroponics

Hydroponics (from the Greek words hydro water and ponos labour) is a method of growing plants using mineral nutrient solutions, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, or mineral wool.

When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics.

Advantages of growing with hydroponics is that the yield of your crop will be higher.

Hydroponic Techniques

• Aeroponics: is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium.
• Ebb and Flow or Flood and Drain: is a form of hydroponics that is known for its simplicity, reliability of operation, and low initial investment, while providing the advantages of hydroponics. Also called 'E&F', it is a system of arranging pots filled with inert media which do not function like soil, contributing nutrition to the plants; rather, the medium anchors the roots and functions as a temporary reserve of water and solvent mineral nutrients as the hydroponic solution is alternately flooded and allowed to ebb.
• In Top irrigation, nutrient solution is periodically applied to the medium surface. This may be done manually once per day in large containers of some media, such as sand. Usually, it is automated with a pump, timer and drip irrigation tubing to deliver nutrient solution as frequently as 5 to 10 minutes every hour.
• Deep water culture: The hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient rich, oxygenated water.
