2. Essential Question: What is hydroponics?
Objectives:
Explain the meaning and importance of hydroponics.
Discuss plant growth requirements.
Evaluate the crops suited to hydroponics.
Analyze the management of hydroponics plant production.

3. Hydroponics:
Production of plants without soil.

4. Hydroponics Systems Aggregate culture Water, aquaculture, nutriculture
Aeroponics
Continuous flow system

5. Aggregate Culture
growing in sand, gravel, marbles

6. Water, Aquaculture, Nutriculture
plants grown in water containing dissolved nutrients.

7. Aeroponics
roots hang in air and are sprayed with nutrient solution.

8. Continuous Flow System
nutrient solution flows constantly over plant roots. Most commonly used for commercial production.

9. Advantages less pests no weeds Optimum Nutrients
Higher Yields ( you get more crop)

10. Disadvantages High startup cost High production cost
Rapid spread of disease
Difficult pollination in green house
