Vertical farming: the future of sustainable agriculture

“Why can’t we grow vertically when we can live vertically?” This question encompasses the essence of vertical farming, an innovative agricultural approach that has the potential to revolutionize food production and sustainability. Vertical farming is about growing crops in vertically stacked tiers or integrated structures without using soil. Advanced indoor farming techniques and controlled environment agriculture (CEA) technologies are used. By manipulating environmental factors such as light, humidity, temperature and nutrient levels, vertical farming aims to optimize plant growth and increase crop yields. This article will explore the concept, benefits and techniques of vertical farming, a breakthrough innovation that has finally become a reality.

Vertical farming concept

Vertical farming involves the practice of growing crops in layers using various soil-less growing methods such as hydroponics, aquaponics, and aeroponics. These methods enable efficient plant growth and resource utilization. Vertical cropping systems can be housed in buildings, containers, tunnels or disused mine shafts, making them a versatile and scalable solution for urban and remote areas.

Needs of Vertical Agriculture

The benefits of vertical farming are many and address key challenges facing traditional agriculture. Some of the main advantages are:

  • Independence from weather: Vertical farming eliminates dependence on weather conditions, allows year-round production of crops, and gets by with limited acreage.
  • Water efficiency: This method uses water more efficiently than conventional farming methods and helps to conserve a precious resource.
  • Simplified management: Vertical farming simplifies occupational tasks such as irrigation and other plant care activities.
  • Reduced deforestation and land use: Vertical farming minimizes deforestation and land use, resulting in less erosion and flooding.
  • Weather protected: Crops are protected from extreme weather events such as floods, droughts and snowfalls.
  • Reduced need for transportation: Locally grown crops reduce the need for long-distance transportation, contributing to lower carbon emissions and less pollution.
  • Waste recycling: organic waste from cities can be recycled and used directly in vertical agriculture buildings, benefiting overall environmental health.

Vertical farming techniques

Vertical farming uses a variety of techniques to ensure optimal plant growth and resource utilization. One of the most widely used methods is hydroponics. In this process, plants are grown without soil, with their roots immersed in nutrient-rich solutions. Inert media such as gravel, sand or sawdust serve as support for the roots.

System requirements for hydroponics

  • pH control: The pH should be between 5 and 7 or slightly acidic.
  • Electrical conductivity: The electrical conductivity of the nutrient solution should be in the range of 1.2 to 3.5 mS/cm.
  • Horticultural lighting: plants need direct sunlight or supplemental lighting for 8-10 hours per day.
  • Temperature: Plants thrive at temperatures between 10 and 30 degrees Celsius.
  • Nutrients: A nutrient-rich formula with nitrogen, phosphorus and potassium is essential for plant growth.
  • Oxygen: Additional oxygen supply ensures optimal nutrient uptake for the plants.
  • Structure and support: support rods and strings are usually needed to help plants grow vertically.

Clitec’s contribution to vertical farming

These chambers provide controlled environments where growers can manipulate and regulate various environmental factors such as temperature, humidity and lighting. By simulating specific climatic conditions, these chambers allow farmers to experiment, conduct research and optimize cultivation techniques. They provide a platform for plant variety selection, breeding and the development of new varieties that thrive in vertical growing systems. In addition, climate chambers enable year-round crop production by bypassing seasonal limitations and providing a consistent environment for plant growth. They also contribute to disease and pest control, as the sealed chambers prevent the entry of pathogens and pests, reduce the use of chemical pesticides, and maintain the health of crops. In addition, these chambers promote efficient resource use by providing precise control over water use, nutrient application and energy consumption. By integrating climate chambers into their vertical farming operations, growers can scale production and ensure consistent, high-quality crop yields.

Clitec GmbH ‘s climate chambers provide vertical farmers with the tools and technology to overcome environmental constraints and maximize their crop yields. The chambers provide scalability and replication capabilities, allowing growers to replicate optimal growing conditions across multiple vertical growing units. This ensures consistency and uniformity in crop production and allows farmers to meet the demands of a growing population. In addition, the controlled environments provided by climate chambers contribute to sustainable and resilient food production by reducing dependence on external weather conditions and minimizing resource waste. By leveraging these chambers, farmers can push the boundaries of innovation in vertical farming, helping to develop sustainable agricultural practices and improve global food security


Vertical farming offers a promising solution to the challenges of traditional agriculture and has the potential to transform sustainable food production. By maximizing resource efficiency, reducing environmental impact, and providing a local and resilient food supply, vertical farming points the way to a greener and safer future. As we approach 2050, vertical farming is poised to become a critical tool for feeding the world’s growing population while conserving our limited natural resources.
