From Living Building Science
The Kendeda Building at Georgia Tech is one of the most sustainable buildings in the world because of its certification as a living building. Under the guidelines of the Living Building Challenge, there are 7 petals that buildings must fulfill: Beauty, Equity, Materials, Place, Water, Energy, and Health and Happiness. Of these 7, the Hydroponics team is primarily focused on Place, with an interest in Water. The Place petal focuses on urban agriculture; the process of growing food in a city environment. Given the unique qualities of a hydroponic system - soilless and water efficient - it is an excellent way to fulfill the Place petal.
Hydroponic systems are classified as two types: open and closed. For the scope of this project, a closed wick system, which is both convenient and cost-effective, will be used. A simple wick system consists of a tank with a tray of pots resting on the lid. The tank is filled with a nutrient solution that contains the essential macro and micro nutrients that plants need to survive. Holes are cut into the tank lid so synthetic wicks can run from the pots to the nutrient solution below. The pots are filled with a soilless growing medium; typically coconut fiber or vermiculite, a type of mineral. Additionally, an air pump and air stone are used to oxygenate the nutrient solution so the plants do not suffocate. Plants receive nutrients via capillary action as the nutrient solution travels up the wick.
