If the quality drops, it directly affects the value of our plants. Gardin helped us clearly identify when our plants were receiving too much light. By adjusting our shading strategy based on that insight, the plants are healthier and growing better, which helps us consistently deliver the quality our customers expect." - **Maurits Kooijman, Head Grower at KP Holland** "Gardin helped us clearly identify when our plants were receiving too much light. By adjusting our shading strategy based on that insight, the plants are now healthier and growing better than before. We now use the data every day to monitor how the plants respond." - **Dr Sander Hogewoning, Director of Plant Lighting B.V** "Gardin could reliably detect the transition of CAM-phase III into IV with its sensor. Moreover, it was able to rapidly detect the malate depletion across multiple cultivars simultaneously and repeatedly at varying temperatures. I see strong potential for its use in commercial orchid cultivation, phenotyping plant research, and genetic breeding." - **Rob Van Enckevort, Owner and Grower** "We pay closer attention to the shading strategy now we work with Gardin, and take better steps to plan for periods of high light, like we have seen this year. Gardin has helped us to think more about the long-term effects of our crop strategy on plant health rather than choosing short term gains." - **Erik Lundgren, Co-founder and Chief R&D Officer** "Working with Gardin enabled us to explore a new technology and collect useful observations that strengthen our understanding of plant performance. These insights add value to our internal development work and help us assess how real-time plant data may support future optimisation efforts." - **Csaba Hornyik, Head of Science** "For the first time, Gardin's advanced sensors have enabled us to remotely explore plant activity in an industrial setting. This breakthrough has been a significant milestone in our quest to perfect recipe development and crucial for creating the optimal plant environment." - **Scott Philips, Group Development Director Berry Farming, Agriculture Investments** "Gardin cameras have become an integral part of our LED strawberry production. They support both our long-term crop and site planning as well as our day-to-day understanding of crop performance. They've quickly become an essential tool for our team. We see even more possibilities for how this technology can support our production in the future." - **Leonard Boer, Owner and Grower** "Before, I mainly focused on the climate conditions in the greenhouse...with Gardin I can measure the effect of the climate conditions based on the plants themselves. The sensor data contributes to a homogeneous production of high quality and to cost control. On balance, I estimate that the result per square meter is at least 5% higher." - **Stijn Jochems, Researcher** "Gardin sensors added value in seeing a response before we saw the crop deteriorating. I could definitely see the sensors being used to enhance quality and yield in lit crops, particularly as a way to increase their light use efficiency."
