Optimizing Nighttime LED Lighting to Accelerate Flowering of Long-Day Plants
Growers often face the challenge of promoting early flowering in long-day plants during seasons with short natural daylight hours. A recent study by Dr. Qingwu Meng and Thomas J. Kramer from the University of Delaware, supported by AFE, offers practical insights into how different types and durations of nighttime LED lighting can enhance flowering in crops like snapdragons and petunias. By adjusting lighting strategies, growers can reduce production cycles, save costs, and improve plant quality. Key Findings The study revealed that the spectrum of light plays a significant role in influencing flowering in long-day plants. Snapdragons and petunias showed distinct responses to warm-white (WW) and red + far-red (R+FR) LEDs. Snapdragons flowered up to 28% earlier under R+FR LEDs due…
