Hydroponics Hydroponics

Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Plants may be grown with their roots in the mineral nutrient solution only, or in medium such as gravel, mineral wool, expanded clay or coconut husk.

Researchers discovered in the 18th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. 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 plant will grow using hydroponics.

Advantages

    Some of the reasons why hydroponics is being adapted around the world for food production are the following:
  • No soil is needed for hydroponics
  • The water stays in the system and can be reused - resulting in lower water costs
  • It is possible to control the nutrition levels in their entirety - resulting in lower nutrition costs
  • No nutrition pollution is released into the environment because of the controlled system
  • Stable and high yields
  • Pests and diseases are easier to get rid of than in soil because of the container's mobility
  • It is easier to harvest
  • No pesticide damage
  • Plants grow healthier
  • It is better for consumption
  • Growing possible any time day or night and all year round
Disadvantages

Without soil as a buffer, any failure to the hydroponic system leads to rapid plant death. Other disadvantages include pathogen attacks such as damp-off due to Verticillium wilt caused by the high moisture levels associated with hydroponics and over watering of soil based plants. Also, many hydroponic plants require different fertilizers and containment systems.

Techniques

The two main types of hydroponics are solution culture and medium culture. Solution culture does not use a solid medium for the roots, just the nutrient solution. The three main types of solution cultures are static solution culture, continuous-flow solution culture and aeroponics. The medium culture method has a solid medium for the roots and is named for the type of medium, e.g., sand culture, gravel culture, or rockwool culture.There are two main variations for each medium, sub-irrigation and top irrigation. For all techniques, most hydroponic reservoirs are now built of plastic, but other materials have been used including concrete, glass, metal, vegetable solids, and wood. The containers should exclude light to prevent algae growth in the nutrient solution.
