Hydroponic Systems & Plant Requirements
|In this system, you can find the nutrient solution in the reservoir, the plant suspended in a tray, and the tray filled with a medium. This system demonstrates capillary action.
|In this system, nutrient solution is held in a reservoir, the solution is pumped into growing chamber and drains back into the reservoir. This system is known as:
|Ebb & Flow
|This system has nutrient pumped from the reservoir through thin tubes that release the solution at the base of the plant. This system is known as:
|This system allows the nutrient solution to circulate over the plant roots through the use of gravity.
|Nutrient Film Technique
|This system has a main reservoir, plants grow in the lid of the system and roots are submerged in nutrient and oxygen rich solution.
|Deep Water Culture
|This systems roots are suspended is air and nutrient solution is sprayed onto the root.It uses no growing medium and requires a lot of supervision.
|What is the purpose of a medium?
|Support plant roots
|What are the basic requirements for plant life?
|Water, Air, Light, Nutrients, Support
|What needs to be monitored consistently to ensure good growing conditions?
|producing plants using nutrients from the byproduct of fish
|The acidity of water is known as
|Fish byproduct has ammonia which can be broken down into nutrients called
|Nitrites and Nitrates
|What is the definition of hydroponics?
|the growing plants in a water and nutrient solution, without soil.
|Why should plants be exposed to cold water?
|Cold water has more oxygen
|What is the ideal temperature of water for plant growth?
|What are the three main nutrients required for plant growth?
|Nitrogen (N) Phosphorous (P) Potassium (K)
|Plants need between this many hours of light for optimal growth:
|What are the uses of hydroponics?
|Restore air quality, re-purpose buildings, controlled environment, feed a growing population, grow anywhere
|What are the benefits of hydroponics?
