  1. Hydroponics Introduction to Agriculture Original Power Point Created by Mike White Modified by Georgia Agricultural Education Curriculum Office June 2002

  2. Terms • Hydroponics: • growing of plants in a solutions of nutrients, without soil • Substrate: • substance in which plant takes root

  3. General Facts • Any plant can be grown in hydroponics. • Almost any system can achieve acceptable growth. • Small scale hydroponics is different to large scale.

  4. General Facts • Hydroponics contributes to understanding plant growth. • Very few commercial producers. • Mainly experimental.

  5. Hydroponic Requirements • Best possible light • 50% or more humidity • Day temp = 75 deg. • Night temp = 65 deg.

  6. Other Requirements • All essential elements needed • The larger the particle size of substrate the more watering needed.

  7. Commercial Production • Minimum of 100,000 sq ft • Thousands of plants needed • Will be able to tell conditions of water by looking at the plants

  8. Advantages of Hydroponics • Reduced land cost • More control over growing environment • Reduced pesticide use • Year-round supply • Alternative to urban sprawl

  9. Disadvantages of Hydroponics • Start-up costs • Management • Labor requirements
