What is AEROPONICS?
Aeroponics is the growing of plants
in air or misty conditions without
using soil or any other medium. This
is similar to hydroponics (growing of
plants in water) just that air
substitutes water in this cultivation.
How does Aeroponics work?
•The plant is kept
suspended above the
ground. Its roots
doesn’t touch any soil.
•Nutrient-filled water is
then sprayed onto the
plant’s roots.
How does Aeroponics work?
What’s the advantage of aeroponics?
• More ecologically friendly as less water and energy
is used
• Since less water is used, more plants can be grown
on the same plot of land
• Nearly insect-free as plants don’t have contact with
soil are kept in a closed space
• No use of pesticides
• Limited transmission of plant diseases as plants are
not interconnected to each other by soil
• Plants grow better as they have more access to
carbon dioxide as they grow in air
Advantages of aeroponics
• Not affected by the four seasons, droughts
or floods
• Improved nutrient feeding to increase the
quality of the plant
• No crop rotation needed because no soil is
used
• Able to cultivate plants out of the
atmosphere
What are the disadvantages of
aeroponics?
• It is difficult to maintain the state-of-theart machinery required in aeroponics
• The machines must be in tip top conditions
because the plant relies heavily on the
nutrients supplied by the machineries
Why do people choose to use
aeroponics?
This state-of-the-art technology in
cultivating vegetables is used
when countries face a scarcity of
land and water.
Singapore and Aeroponics
There is one Aeroponics farm in Singapore
called ‘Green Rose’. This is one and only one
of its kind. It covers 5.3 ha of land and
produces vegetables and herbs that are
sold in local supermarkets.
History of Aeroponics
• Commercialization of aeroponics began in
1966
• The first aeroponically-grown vegetables
were sold in grocery stores in 1986
• However, aeroponics were first introduced in
labs in 1940s
• So, aeroponics have come a long way since
plants in the lab to vegetables are cultivated
world-wide
Space plants
America have been trying to cultivate plants in
outer-space where there is no soil. So, they
experiment with hydroponics and aeroponics.
In 1960, plants to sent out of the Earth’s orbit to
test the sutability of cultivating plants out of
the Earth’s atmosphere.
However, plants have shown slow growth due
to the lack of gravity. But results also have
shown that the plants will have higher levels of
potassium and phosphorus if grown in outerspace.
