Shedding Light on Tomato Growth: Why Spectrum Matters

15 November 2025 | Int. Greenhouse Guide |

Light is more than just brightness, it’s the engine of plant life. In greenhouse and vertical farming environments, the quality of light matters just as much as the quantity. Recent research shows that dynamic lighting, adjusting color spectrum and intensity throughout the day, can significantly improve tomato growth, yield, and even flavor. Static LED setups may provide consistent light, but they can’t match the natural rhythm that plants evolved under.

A recent trial in Leamington, Ontario, compared traditional static LEDs with dynamic spectrum lighting from Sollum Technologies. The results were striking: tomato yields increased by nearly 20%, with stronger, more uniform plants, all under identical growing conditions. By tailoring the light spectrum to mimic sunrise, midday, and sunset, growers can now fine-tune photosynthesis and energy efficiency like never before.

Whether you’re managing a greenhouse, vertical farm, or exploring new agritech solutions, understanding the science of light spectrum could transform how you grow. Learn how dynamic lighting systems are reshaping controlled environment agriculture and helping farmers achieve smarter, more sustainable results.
