Indoor agriculture, often called controlled environment agriculture (CEA), represents a revolutionary approach to farming that addresses the challenges of traditional outdoor cultivation. As the global population burgeons and environmental concerns intensify, the need for sustainable and efficient food production methods has never been more pronounced.

In this article, we try to understand the significant role of fabric ducts in optimizing indoor agriculture environments. These innovative duct systems offer precise climate control, enhanced energy efficiency, and customized airflow solutions, ultimately fostering healthier crops and sustainable farming practices.

The Need for Indoor Agriculture

The need for indoor agriculture has become increasingly evident in the face of challenges posed by traditional outdoor farming. Climate change, urbanization, and population growth have exposed the vulnerabilities of traditional agriculture, with unpredictable weather, dwindling arable land, and unsustainable practices threatening global food security. Indoor agriculture, also known as controlled environment agriculture (CEA), offers a solution.

Cultivating crops in regulated indoor environments mitigates these challenges, enhances resource efficiency, and ensures a consistent food supply. Its adaptability to various locations and reduced environmental impact make indoor agriculture a vital component of the sustainable future of food production.

Fabric Ducts: An Overview

Fabric or textile ducts are a modern alternative to traditional metal ductwork systems. Made from high-quality fabrics like polyester or nylon, they are crucial in optimizing indoor environments, such as commercial, industrial, and agricultural spaces. Here’s a brief overview:

Advantages of Fabric Ducts in Indoor Agriculture

Material and Design

Fabric ducts are flexible and designed for even air distribution. They come in various shapes, sizes, and colors, allowing customization to match the space’s aesthetics.


Fabric ducts find use in commercial, industrial, and agricultural settings, where uniform air distribution, customization, and energy efficiency are essential.

Uniform Air Distribution

Fabric ducts evenly distribute conditioned air throughout the growing area, ensuring consistent temperature and humidity levels critical for plant health and yield optimization.

Energy Efficiency

Fabric ducts reduce the energy consumption of HVAC systems. They require lower air pressure, resulting in decreased energy costs and a smaller environmental footprint.

Condensation Control

Fabric ducts can be designed to prevent condensation buildup, reducing the risk of mold and mildew growth on crops, which is essential for maintaining crop quality and hygiene.

Customizable Design

Fabric ducts offer flexibility in design, allowing growers to tailor the airflow patterns to specific crop needs. This customization can optimize growing conditions and maximize yields.

Easy Installation and Maintenance

Fabric ducts are lightweight and easy to install, saving time and labor during setup. They are also simple to clean and maintain, contributing to the overall efficiency of the indoor farming system.

Noise Reduction

Fabric ducts can help reduce noise levels in indoor agriculture environments, creating a more comfortable working environment for staff and minimizing stress on crops.

Aesthetic Integration

Fabric ducts come in various colors and designs, enabling them to blend seamlessly with the facility’s aesthetics. This enhances the overall appearance and promotes a positive working environment.

Material Options

Fabric ducts can be manufactured using materials with specific properties, such as antimicrobial coatings for enhanced crop hygiene and fire-resistant options for safety, ensuring suitability for diverse indoor agriculture needs.


High-quality fabric ducts are durable and can withstand the demanding conditions of indoor agriculture facilities, offering long-term value and reliability.


Fabric ducts can be easily reconfigured or expanded as the indoor agriculture operation grows or changes, providing scalability and cost-efficiency.

Case Study: Prihoda Fabric Ducts

Dive deeper into details with our project details:

Prihoda and the Eden Project in Cornwall

Prihoda, a leading provider of fabric ducting systems, embarked on a high-profile partnership with the renowned Eden Project in Cornwall. The Eden Project, famous for its striking biomes and lush botanical gardens, sought Prihoda’s expertise to enhance the air distribution in its restaurant areas.

The Eden Project, Located near St Blazey, Cornwall, is a sprawling complex featuring massive greenhouse structures. It attracts over a million visitors annually who explore two climate-controlled megadomes—one simulating a rainforest environment and the other a Mediterranean climate. Surrounding these domes is an extensive botanical garden showcasing native flora and fauna, including prehistoric species.

Project Requirements

Prihoda ensured two distinct air patterns within the main restaurant and café areas—the Med Restaurant and the Eden Kitchen. One pattern aimed to direct conditioned air into the occupied seating zones, while the other needed to flow over the serving counters, mixing with and slowing down air velocity to avoid discomfort for staff serving visitors.

Prihoda’s Solution

Prihoda devised a single fabric ducting installation accommodating air distribution patterns. Large-diameter laser-cut perforations were positioned at the front of each duct for the seated areas, efficiently delivering air at the desired velocity to the occupied seating areas. For the serving staff, Prihoda utilized micro-perforations—rows of tiny laser-cut holes, each measuring four-tenths of a millimeter in diameter. This design ensured a high air volume at very low velocity, providing fresh and cool air directly into the service environment.

Innovative Lighting Integration

The Eden Project envisioned incorporating LED lighting into the fabric ducting. Prihoda’s design team demonstrated their adaptability and creativity by proposing a solution. During production, they sewed LED lighting strips, attached to velcro strips, along the entire length of the half-round fabric ducts. This design not only met the aesthetic requirements but also facilitated easier installation.

Quality Fabric Selection

Prihoda’s commitment to quality led them to use Premium fabric for the Eden Project installation. Premium fabric is known for its anti-static and flame-retardant properties, making it ideal for a food environment. Moreover, this fabric is antimicrobial, non-hygroscopic, and non-shrink, ensuring compliance with stringent hygiene standards.

Cleanroom Quality Assurance

Given the installation’s location in a food environment, Prihoda went the extra mile by providing fabric ducting material certified to ISO4 – Class 10 standards. This ensured that no fibrous materials from the ducting would enter the supply air system, maintaining a clean and safe environment.

The partnership between Prihoda and the Eden Project exemplifies the company’s dedication to delivering innovative, high-quality fabric ducting solutions tailored to the unique requirements of their clients.

Prihoda’s Eden Project

The collaboration between Prihoda and the iconic Eden Project is a testament to the innovative capabilities of fabric ducting systems in optimizing indoor environments. Prihoda’s expertise in providing precise air distribution, innovative lighting integration, and superior fabric quality has enhanced the comfort of visitors and staff and exemplified the adaptability and sustainability of indoor agricultural solutions. This partnership underscores the critical role played by advanced ventilation systems in creating efficient, aesthetically pleasing, and environmentally conscious indoor spaces, paving the way for a more sustainable future in controlled environment agriculture.
