Hydroponics Flashcard

Front

What is hydroponics?

Back

Hydroponics is the method of growing plants in a liquid nutrient solution instead of soil.

Front

What is the purpose of adding dilute sulfuric acid in hydroponic systems?

Back

To decrease the pH of the nutrient solution.

Front

What is the main function of the air pump in the Water Culture System?

Back

To supply air to the airstone, ensuring oxygen is available for the roots.

Front

Which hydroponic system is the most widely used in the world?

Back

The Drip System is the most widely used hydroponic system.

Front

What is a benefit of hydroponics in underdeveloped countries?

Back

Hydroponics is feasible in areas of poor soil conditions, allowing for food production where traditional farming may not be possible.

Front

What is the role of nutrients in hydroponics?

Back

Nutrients provide essential elements for plant growth, including nitrogen, phosphorus, potassium, and micronutrients.

Front

What is pH, and why is it important in hydroponics?

Back

pH measures the acidity or alkalinity of the nutrient solution, which affects nutrient availability to plants.

Front

What are the main components of a hydroponic system?

Back

The main components include a nutrient solution, a growing medium, a water delivery system, and a light source.

Front

What is the difference between passive and active hydroponic systems?

Back

Passive systems rely on capillary action to deliver nutrients, while active systems use pumps to circulate the nutrient solution.

Front

What is the Nutrient Film Technique (NFT)?

Back

NFT is a hydroponic system where a thin film of nutrient solution flows over the roots of plants, providing them with nutrients and oxygen.
