Hydroponics

Front

What is hydroponics?

Back

Hydroponics is the cultivation of plants in water without the use of traditional soil.

Front

What is nutrient film technique?

Back

A hydroponic method where a thin film of nutrient solution is continuously supplied to the roots housed in a thin, plastic liner.

Front

What is the floating raft system in hydroponics?

Back

A growing method where plants are supported by polystyrene sheets that float on aerated nutrient solution.

Front

What is aeroponics?

Back

A water culture system where plants are grown in containers with their roots suspended and nourished by a nutrient mist.

Front

What is an open hydroponic system?

Back

A system where nutrient solution is provided to the roots of the plant, but the excess solution is not reused.

Front

What is a closed hydroponic system?

Back

A system where the nutrient solution is recirculated and reused, minimizing waste.

Front

What is aquaponics?

Back

A sustainable farming method that combines aquaculture (raising fish) with hydroponics (growing plants) in a symbiotic environment.

Front

What are the advantages of hydroponics?

Back

Hydroponics allows for faster plant growth, efficient use of water, and the ability to grow in areas with poor soil.

Front

What is the role of pH in hydroponics?

Back

pH affects nutrient availability; maintaining the correct pH (usually between 5.5 and 6.5) is crucial for optimal plant growth.

Front

What are the essential nutrients for hydroponic plants?

Back

Essential nutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements like iron and manganese.
