A few month ago i came across an article about a guy who want ,my country(Singapore) which is a dense island state to be more self sufficient in our food supply buy using hydroponics to grow vegetables on the roof of all the buildings in Singapore.
This sparked my interest which led me to this little project. A huge percentage of the cost of your fruits and vegetables came from the transportation and keeping it fresh for the journey by refrigeration which also cause lots of co2 emmisions.
So the closer the source of food it is to you the better.
What is Hydroponics?
Hydroponics is growing plants in water instead of soil .
It has many advantages over traditional growing such as it requires less water as water could be recycles instead of letting most of the water flow into the ground,easier to control its nutrients, no need for pesticide offers much higher yields per square foot and the best of all able to grow indoors without attracting disgusting insects.
