Hydroponics
- is a method of growing plants using mineral nutrient solutions, in water and 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, mineral wool or coconut husk.
Advantages
-No soil is needed
-The water stays in the system and can be reused - thus, lower water costs
-It is possible to control the nutrition levels in their entirely - thus, 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.
Disadvantages
-The hydroponic conditions (presence of fertilizer and high humidity) create an environment that stimulates salmonella growth. -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.
-Many hydroponic plants require different fertilizers and containment systems.
