Gardin Photosynthesis Sensor and AI Platform

Gardin Agritech is a United Kingdom precision agriculture company based in Oxford, with a registered address in Abingdon. It develops technology that measures crop photosynthesis in real time so that growers in controlled environment agriculture can see plant stress and light use before symptoms appear.

The product combines an optical sensor with an AI platform. The sensor reads photosynthetic activity of the crop, and the platform converts the readings into insights for growers on stress detection, light optimisation and energy use. Since its commercial launch in June 2023 it has been deployed in Spain, Morocco, the Netherlands and Canada across more than 20 crop species.

• Real-time photosynthesis measurement: tracks photosynthetic activity of the crop continuously.
• Early stress detection: flags plant stress often before visible symptoms.
• Light optimisation: helps tune lighting and cut energy use.
• Cross-species hardware: affordable, autonomous sensor used on more than 20 crop species.
• AI platform: turns sensor readings into grower insights.
• Research use: supports seed variety research.

Hi-tech greenhouse growers of tomatoes and flowers in Vietnam could tune supplemental lighting using photosynthesis data. Plant factories could cut electricity use. Seed companies and research institutes could screen varieties for stress response.

Detects plant stress early, in some cases weeks before it is visible when crop walking. Supports light optimisation, with 20-30% energy savings reported in trials. Works across crop species with affordable, autonomous and robust hardware. Customers and partners cite yield and profitability gains of up to 15% and 30%.

Energy and labor costs are pushing greenhouse and vertical farm operators to manage light and climate with plant-level data. Vietnam's expanding hi-tech greenhouse and plant factory projects, as well as seed research centers, may benefit from direct measurement of plant physiology.
