Hydroponics
When a little kid explains how to grow plants, he usually includes soil in his list of materials. But thanks to hydroponics, this is no longer necessary. Hydroponics is a system to grow terrestrial plants with their roots inside a mineral nutrient solution in an inert medium, such as gravel, mineral wood, or perlite, instead of soil. There are many advantages to using hydroponics as opposed to growing plants in soil: Water either stays in the system, or is reused Easier to control nutrient levels, especially for aeroponics, and continuous flow hydroponics Controlled, closed system --> no pollution; no pesticides required healthy environment to grow --> steady growth of plants, good yield, healthy plant products for consumption Pests and diseases are easier to get rid of than in soil because of the container's mobility (no need for pesticides) Types of Hydroponics: Solution Culture: uses a solution to supply nutrients to plants. Static: The plant root sits in a jar containing the nutrient-rich solution algae may form if the water is not covered properly -> must use an opaque cover Continuous Flow: the solution containing the nutrients flows through a circuit large storage tank that is separate from the plants easy to maintain the temperature and nutrient concentration
Aeroponics: roots are sprayed with the nutrient solution suspended in the air plants live longer because they get more CO2 and O2 in the air saves water and nutrients, lowering costs
Medium Culture: Roots are placed in a solid medium, and it is named depending on the specific type of medium used. Examples include sand or gravel culture. sub-irrigation top irrigation Reservoirs can be built with plastic, glass, metal, wood, concrete Disadvantages:
Easy to watered (less of a problem for aeroponics, big problem for static system) Hard to keep different types of plants together ( each requires different pH and nutrient levels); need different containment systems Requires a lot of machinery to make sure the system is working in perfect order --> very expensive!!!!!. If not: If something goes wrong in the system, all the plants die very quickly Without soil, it is easy for the pH and nutrient levels to get messed up
