In June, the CF2GO (Chlorophyll Fluorescence 2 Go) was officially launched at the Greentech conference in Amsterdam in the Netherlands, and was nominated out of 47 products for the innovation award by the jury! The CF2GO is a camera system capable of measuring accurate real-time efficiency of photosynthesis and plant stress from a distance by capturing chlorophyll fluorescence signals. Its ability to operate 1 meter away from the plant with high accuracy sets it apart from traditional sensors, that often work with leaf clippers. The information that lies in chlorophyll fluorescence has been studied over the last 80 years at universities and research groups. The past ~20 years, this fundamental research has been implemented in practical applications that are used in agriculture (mainly by large breeding companies, multinationals and universities). The integration of this technique into a camera system with a small body that can measure from afar is novel, and marks a new step in the usage of photosynthesis sensors as it makes its way into greenhouses. With real-time data on efficiency of photosynthesis and stress indicators, deeper insights into crop performance can be obtained, enabling more informed decisions in cultivation practices. The camera can be mounted either stationary, or on for instance a robotic arm that moves throughout the greenhouse. The CF2GO is already operational in four commercial greenhouses (two for validation and fine-tuning of the product). In the magazine 'In Greenhouses', or 'Onder Glas' in Dutch, cultivation manager Johan Langelaan from Maarel Orchids explains why they started integrating the CF2GO in their cultivation. He explains: "We can now see in real-time when the plants require more or less light for photosynthesis, allowing us to adjust screening and lighting immediately. We can do this without fear of potential damage from too much or too little light. This way, we get more out of the crop and can grow with greater confidence". Another important advantage they mention is that no interpretation is required: “because you get hard facts and measured values from the system, and you can immediately see what they mean”. Maarel Orchids is now actively working on integrating the measurements with the climate computer to automate lighting and shading controls, which is something that is mostly done manually still. The article can be found at: https://www.onderglas.nl/gewas-krijgt-exact-de-hoeveelheid-licht-die-het-nodig-heeft/ In this blog, I will explore the technical specifications of the CF2GO and how it captures its measurements. I will also showcase data from experiments and real-world examples from greenhouses, demonstrating what photosynthesis and stress data look like and how this information can be used to optimize cultivation practices.
