Hydroponic Systems & Plant Requirements
Question | Answer |
---|---|
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. | Wick |
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: | Drip |
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. | Aeroponics |
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? | pH |
Aquaponics is... | producing plants using nutrients from the byproduct of fish |
The acidity of water is known as | pH |
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? | 55-65 degrees |
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: | 14-16 hours |
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? | See note packet. |
