nocamels: Buying organic and locally grown produce is a raging trend that is here to stay. And a new project in Israel called “Green in the City” is taking the trend to a whole new level, literally.
‘Green in the City’ grows mostly organic vegetables in floating beds of water (without soil) on the rooftop of Dizengoff Center, Tel Aviv’s central mall complex. Started by Mendi Falk, the project aims to bring the farm to the city, and fresh produce onto urban dwellers’ plates.
The science behind this intriguing project is hydroponics, a type of gardening that grows plants using very little nutrient-rich water solutions and without any soil. There are different types of hydroponic systems, but they all essentially work by pumping just the right amount of nutrients and water directly to the plants’ roots. Unlike traditional agriculture, hydroponic gardening gives the grower control over the plants’ watering and feeding cycles, as well as over the strength and acidity of the nutrient solution that is given to the plants.
Falk’s farm also utilizes an aquaponics system: fish are grown in a tank that is connected to the plant growing beds, with water circulating between each other. The plants take in nutrients from the fish tank’s waste and clean the water that is pumped back into it.
