What is Hydroponics?

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

SLIDE 3

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

SLIDE 5

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
