What is Indoor Farming?

An Introduction to Indoor Farming

Indoor farming, commonly referred to as vertical farming or controlled environment agriculture, has been around in its modern state for about 20 years. This innovative approach to agriculture encompasses a wide array of applications, including the cultivation of food, flavours, fragrances, and medicinal plants. Indoor farms boast several distinct attributes that set them apart from traditional farming methods:

  • Crops are grown indoors, year-round, away from the risks of mother nature
  • Plants are raised using artificial lighting
  • Most often are soilless, using either hydroponic, aquaponic, or aeroponic nutrient delivery methods
  • Uses climate control to enhance plant health and vitality

Different types of vertical farming incorporate various aspects of controlled-environment agriculture (CEA). These indoor growing systems are commonly housed in larger warehouses or shipping containers. Within these setups, plants thrive under LED lights, organized in layered stacks or tall wall towers. This optimized configuration produces maximum yield within a compact footprint while maintaining optimal growing conditions.

How It Started

The History of Indoor Farming

The concept of vertical farming took root in the early 2000s when Dickson Despommier, a professor at Columbia University, challenged his students to envision the world’s first indoor vertical farm. Their groundbreaking design featured innovative elements such as grow lights and conveyor belts, laying the foundation for future developments in this field.

By the mid-2000s, vertical farming companies started attracting substantial investments, with millions of dollars pouring in to support their pioneering ventures. The investment community recognized the potential of new technologies to revolutionize indoor farming, including robotics, LED lighting, and artificial intelligence.

This trend persisted for nearly a decade as vertical farming companies gained momentum by highlighting the efficiencies achieved through cutting-edge operating systems and advanced lighting technologies. Notably, the vertical farming industry emerged as one of the most exciting investment opportunities in the aftermath of the 2020 pandemic, capturing widespread attention and interest from investors.

The Benefits of Indoor Farming

Indoor farming offers a multitude of benefits that make it a compelling solution for modern agriculture. Indoor farming is a promising solution that addresses the challenges of limited arable land, climate change, and the growing global population while providing fresh, safe, and locally sourced produce. As the world continues to grapple with environmental challenges and the need for food security, vertical farming stands out as an innovative industry poised to shape the future of farming.

Water Savings

Water Savings

Indoor farms have the potential to significantly reduce water consumption compared to field-grown crops, with achievable reductions of up to 95% depending on the HVAC technology employed. By utilizing sophisticated systems that control temperature, humidity, and nutrient delivery, indoor farming minimizes water waste through efficient irrigation practices.


Land Recovery

Traditional agriculture relies on vast expanses of arable land, which can lead to deforestation, habitat loss, and soil degradation. Indoor farming maximizes land efficiency by utilizing vertical space and compact setups. Indoor farming represents a sustainable and resource-efficient approach to food production while safeguarding our valuable land resources.



Indoor farming has the remarkable ability to simplify supply chains and serve as a reliable year-round source of food. By cultivating crops in controlled environments, these farms eliminate the dependence on seasonal variations and external factors that often disrupt traditional agricultural practices, ensuring a consistent and steady supply of fresh produce year-round.



Through precise control over growing conditions, indoor farms minimize crop waste. Factors such as temperature, humidity, and nutrient levels are carefully regulated, resulting in healthier and more resilient plants. In addition, advanced monitoring systems allow for early detection of plant diseases or pest infestations, enabling prompt intervention and reducing crop losses.
