New research from the University of Wyoming has found that the timing and direction of far-red light exposure can significantly affect the growth, fruit quality, and nutrient uptake of June-bearing strawberries. The studies highlight that far-red light is not just a supplement to standard lighting, but a factor that must be precisely managed to optimize yield and efficiency in controlled-environment strawberry production.

Why it matters

As LED technology enables more precise control over light quality, understanding the role of far-red light in strawberry cultivation can help growers refine their practices to improve fruit yield and quality while supporting efficient resource use. The findings advance the scientific understanding of light management in strawberry production.

The details

The studies showed that carefully timed applications of far-red light can enhance strawberry plant growth, improve fruit quality, and support nutrient uptake. Experiments on light direction also demonstrated that where far-red light is delivered - whether from above, below, or laterally - can strongly influence plant architecture and fruit development.

What they’re saying

“Together, the findings highlight that far-red light is not only a supplement to standard lighting but also a factor that must be precisely managed. Optimizing both the timing and direction of far-red exposure offers growers new strategies to improve fruit yield and quality while supporting efficient resource use in production systems.”

The takeaway

This research demonstrates the importance of carefully managing the timing and direction of far-red light exposure in controlled-environment strawberry production to optimize plant growth, fruit quality, and resource efficiency. The findings provide practical insights for growers seeking to refine their cultivation practices and leverage emerging LED technology.
