Amid the ongoing water crisis in the Middle East, an Iranian architectural group at the request of Shiraz municipality has designed modern vertical gardens which are irrigated by the gray water of the tower’s recycling and hydroponic system.
Hydroponics is a method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources.
According to a Farsi report by Science and Technology News (stnews.ir), 600 pre-fabricated units of this tower façade are going to be built with high-tech technology in Shiraz which is a historic city in Southwestern Fars Province. These units get mounted on the façade of the tower and will create a sustainable, vertical three-acre garden.
The project’s architects say you will have a natural smell of Shiraz’s plants in this garden.
Iran’s first hydroponic greenhouse is already under construction in Markazi Province. The first phase of the project with an area of 15 hectares became operational in Zarandiyeh County.
Iran has more than 12,000 hectares under greenhouse cultivation. The Agriculture Ministry aims to reach 48,000 hectares by the end of the 20-Year Vision Plan (2005-25).
The ministry plans to transfer all vegetable farms to greenhouses within 10 years.
