Hydroponics Flashcard

Front

What is hydroponics?

Back

A method of growing plants without soil, using nutrient-rich water instead.

Front

What is aquaponics?

Back

A system that combines aquaculture (raising fish) with hydroponics, where fish waste provides nutrients for the plants.

Front

What are macronutrients in hydroponics?

Back

Essential nutrients required in larger amounts for plant growth, including nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.

Front

What is the role of sunlight in hydroponics?

Back

Sunlight is essential for photosynthesis, which allows plants to convert light energy into chemical energy.

Front

Why is soil not used in hydroponics?

Back

Hydroponics relies on nutrient solutions instead of soil to provide plants with the necessary nutrients.

Front

What types of plants are commonly grown in hydroponic systems?

Back

Leafy greens, herbs, and certain fruits like strawberries and tomatoes.

Front

What is the importance of water in hydroponics?

Back

Water serves as the medium for nutrient delivery and is crucial for plant hydration and growth.

Front

What is the difference between hydroponics and traditional soil gardening?

Back

Hydroponics uses nutrient solutions without soil, while traditional gardening relies on soil for nutrients and support.

Front

What is nutrient film technique (NFT) in hydroponics?

Back

A hydroponic system where a thin film of nutrient solution flows over the roots of plants, allowing them to absorb nutrients and oxygen.

Front

What is the purpose of aeration in hydroponics?

Back

Aeration ensures that plant roots receive adequate oxygen, which is essential for healthy growth.
