Hydroponics Flashcard

Front

What is hydroponics?

Back

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

1. Nutrient Film Technique (NFT) 2. Deep Water Culture (DWC) 3. Ebb and Flow (Flood and Drain) 4. Wick System 5. Aeroponics

Front

What is a key feature of Water Culture Systems?

Back

Nutrients are easily absorbed.

Front

What is the role of PVC pipes in hydroponic systems?

Back

To hold plants and provide continuous flow of nutrient solutions.

Front

Where is hydroponics often utilized?

Back

In greenhouses.

Front

What do Continuous Flow Systems utilize to bring nutrient solutions to growing pipes or trays?

Back

Gravity or pumps.

Front

What are micro-nutrients in hydroponics?

Back

Nutrients needed in small quantities.

Front

What is the importance of pH in hydroponics?

Back

pH affects nutrient availability; optimal range is typically between 5.5 and 6.5.

Front

What is the purpose of an air pump in hydroponic systems?

Back

To oxygenate the nutrient solution, promoting root health.

Front

What is the difference between macro-nutrients and micro-nutrients?

Back

Macro-nutrients are needed in larger quantities (e.g., nitrogen, phosphorus), while micro-nutrients are needed in smaller amounts (e.g., iron, zinc).
