Greenhouse artificial lighting management and tips for higher yields
Artificial lighting plays a crucial role in modern greenhouse production, helping growers optimize crop growth, quality, and yield throughout the year. In this session, a leading greenhouse researcher and experienced commercial growers will share practical insights on managing lighting strategies, improving light use efficiency, and getting the most value from lighting investments. Topics include the transition from HPS to LED, balancing plant performance with energy consumption, and understanding why 20% more light does not automatically translate into 20% more production. Speakers will also share lessons learned from daily greenhouse operations and discuss how growers can optimize lighting based on crop needs and economic returns. Attendees will leave with actionable tips and a better understanding of how lighting can support more productive and profitable growing.
Speakers
My Name is Octavio Perez Rodriguez, currently I work for Nature Fresh farms in Delta Ohio, we have 45 acres of LED organic strawberries and 45 acres of HPS tomatoes. I have been working in this industry for almost 20 years, the last 12 year in USA and before I worked in Queretaro, Mexico in the Agropark. I have been working with lit crops for almost 12 years mainly with HPS, and amost five years doing in house research about LED (top and interlighting), but in 2023 we did our first LED crop with strawberries.
My name is Marc Salvany, and I am the Chief Executive Officer and co-owner of Gavita International B.V. Through our flagship brand, Agrolux, we offer future-ready solutions, build strong partnerships, and deliver reliable services to professional growers worldwide. I lead the company’s global growth and transformation, with a strong focus on product innovation, operational excellence, and scalable supply chain and service networks. Before becoming an independent company through a management buy-out in 2025, Gavita was part of Hawthorne’s Professional Horticulture Lighting business, a division of the publicly listed Scotts Miracle-Gro Company. In 2026, we launched the LYRA platform, powered by AgroluxOS and HortiMesh, bringing lighting, data, and control together in one future-ready ecosystem.
My name is Bernard van Loon I currently work as business developer for Delphy Digital with a focus on North America. With past experience as a data scientist and an Msc in Plant Science focused on statistical crop modelling from Wageningen University, my aim is to combine theoretical and practical solutions to help growers take the next step in Data Driven Growing. Light is the key aspect for yield, and understanding how a crop reacts to light during different stages and scenarios is key for yield prediction and crop management. One part of Data Driven Growing with Delphy's QMS solutions is alloiwing a grower a deeper insight into how their lighting (indoor and outdoor) interacts with their crop throughout the growing season.
