Transcript of Hydroponics
Why is this important to me?
There have been great advancements in the last 70 years with hydroponics, making it a up and coming superstar in the way we grow food.
This technique can be used anywhere in the world for both large scale and small scale food production
Finally, this unit will be a major part of your grade! On the plus side, you are growing a plant, that will benefit you in many ways :)
Is hydroponics real?
YES! It is the process of growing plants in sand, gravel, or liquid, with added nutrients but without soil.
This method has been around for thousands of years
So who thought of this?
The Hanging Gardens of Babylon are largely believed to have functioned according to hydroponic principles.
Built around 600 B.C. in Babylonia, or Mesopotamia, the gardens were situated along the Euphrates River.
The area suffered from a dry, arid climate that rarely saw rain, and it's believed that the lush gardens were watered using a chain pull system, which carried water up from the river and allowed it to trickle down to each step or landing of the garden structure.
Anyone else use hydroponics?
During the 10th and 11th centuries, the Aztecs developed a system of floating gardens based on hydroponics.
Driven out of their land, they settled at Lake Tenochtitlan.
Unable to grow crops on the lake's marshy shore, they built rafts out of reeds and roots.
Crops would grow on top of the rafts, their roots reaching through the rafts and down into the water. Marco Polo's writings indicate he witnessed similar floating gardens while visiting China in the late 13th century
