Vertical farming and controlled environment agriculture

Companies active in the field include Edible Garden AG Incorporated, Heliospectra, Priva and Sollum Technologies. Edible Garden operates greenhouse and hydroponic growing facilities, while Heliospectra and Sollum Technologies develop horticultural LED systems. Priva develops greenhouse climate-control and automation systems. These examples span crop production, lighting and environmental control.

Sollum Technologies, Intelligent Growth Solutions Ltd and Oishii Farm Corporation are listed startups in the field. Sollum supplies dynamic LED systems for greenhouse lighting, Intelligent Growth Solutions supplies vertical-farming technology, and Oishii operates indoor vertical farms focused on premium strawberries and other produce. Their work reflects distinct opportunities in lighting, farm systems and crop production.

Wageningen University, Ohio State University and Cornell University are among the named research organizations. Wageningen studies crop production and climate resilience, Ohio State researches indoor-farm production planning and environmental control, and Cornell works on greenhouse lighting and energy optimization. Recent research also includes universities and institutes examining crop quality, energy-water modeling and automated control.

Funding metrics list $749.4 million across 116 grants since 2020, along with 17 funding rounds totaling $794.0 million. These figures represent reported funding associated with the field, rather than a single program or organization. They indicate that public grants and investment rounds both contribute to sector financing.

Autostore Technology AS has the highest listed holder count, with 14 patents. Oishii Farm Corporation has 6, while Nippon Chemical Industrial Co. and Beanstalk Inc. each have 5. Overall patent activity fell 43% in the latest 12-month comparison, even as publications grew 23.6% over the same comparison period.

In September 2026, Intelligent Growth Solutions and James Hutton Institute published a comparison of basil growth, antioxidants and volatile profiles in vertical farms and glasshouses. A separate September 2026 study examined cost-competitive crop-performance targets. In June 2026, Wageningen University & Research launched HortINspire, an international network for protected cultivation.

Machine learning, photoperiod, photosynthesis and plant metabolism are among the emerging terms in the field. Recent work also examines digital twins for adaptive resource control, multi-sensor greenhouse systems and computer vision for crop monitoring. These methods aim to connect plant responses with control decisions, while practical adoption depends on useful data and reliable integration with farm operations.

The main approaches are greenhouse systems, vertical plant factories, hydroponics, aeroponics and aquaponics. Greenhouses combine sunlight with climate management, while plant factories rely on stacked, enclosed growing areas. Hydroponics and aeroponics describe ways of delivering nutrients to roots; aquaponics links plant production with fish systems. Each approach balances environmental control, resource use and operating complexity differently.

The United States leads the listed country data, with 48.2% of documents, followed by the United Kingdom at 14.5% and the Netherlands at 10.5%. Germany and Canada are also prominent in the data. These figures describe document activity, not a direct measure of farm output or commercial deployment.

Leafy greens and herbs, fruiting vegetables, and berries are the main listed applications, with 15,455, 14,818 and 14,600 documents respectively. Other applications include seedlings and transplants, as well as fodder and forage. Crop choice matters because growing systems, lighting needs and commercial economics differ across produce types.
