Energy savings in greenhouses by transition from high-pressure sodium to LED lighting

David Katzin et al.

Summary: This study examines the energy savings potential of transitioning greenhouses from high-pressure sodium (HPS) to LED lighting in high latitude regions. The results show that transitioning to LEDs can lead to a 10-25% reduction in total energy consumption, but may also increase the demand for heating.

High Light Intensity Applied Shortly Before Harvest Improves Lettuce Nutritional Quality and Extends the Shelf Life

Qianxixi Min et al.

Summary: Applying high light intensity shortly before harvest can increase the nutritional quality and freshness of loose-leaf lettuce, while also extending its shelf life. The prolonged shelf life is linked to the improved energy and antioxidant status of the crop at harvest, with higher levels of ascorbic acid and carbohydrates correlating positively with shelf life.

Current status and future challenges in implementing and upscaling vertical farming systems

S. H. van Delden et al.

Summary: Vertical farming systems have the potential to produce food in a climate-resilient manner with reduced pesticides and fertilizers, and lower land and water use compared to conventional agriculture. However, successful integration of vertical farming into mainstream agriculture will require improvements in profitability, energy efficiency, public policy, and consumer acceptance.
