Hydroponics

What is Hydroponics? Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent.

History of Hydroponics - Was used in the ancient world (Hershey) - Hanging Gardens of Babylon - Floating gardens of the Aztec in Mexico - Used by botanists to study plants (Stauffer) - (1699) John Woodward - (1887) Julius von Sachs - (1929) William Frederick Gericke - Wake Island (Hershey)

What are the advantages of Hydroponics? ● Provides sterile environment for plant production ● It needs 20% less space than soil based gardens ● Proven that the vitamin content is 50% more in hydroponically grown plants than in conventional ones ● There is no soil set up ● No need for fertilizers and pesticides

What are the advantages of Hydroponics? ● Water circulation ● Minimal evaporation and runoff ● Weight of water per unit supplied is maximized ● Can be used in dry and urban areas ● Can produce multiple crops in one year
