How to Optimize Light Spectrums for Each Stage of Plant Growth
As your plants transition into the vegetative stage, they require more energy to support the rapid growth of leaves and stems. This stage benefits from a mix of blue and red light, with a higher proportion of blue to red (around a 60:40 ratio).
Redefining PAR: The Impact of Far-Red Photons on Photosynthesis and Horticultural Lighting
The effectiveness of far-red photons in driving photosynthesis means that technologies utilizing these photons, such as downshifting luminescent materials and fixtures that include far-red, should be reevaluated for their effectiveness as plant growth spectrum providers.
Uncovering Spectral Signatures in a Pecan Orchard
Multispectral cameras capture spectral signatures much like a thermometer measures the temperature of the human body. Changes in plant reflectance indicate stress, but additional information is required to identify the cause.

Advanced Mid-Power and High-Power LEDs for Horticulture Lighting
Cree LED's J Series® family offers a comprehensive portfolio of mid-power and high-power LEDs engineered specifically for horticulture lighting. The lineup includes high-efficacy 2835, 3030 and 5050 platforms designed to maximize photon output, energy efficiency, and long-term reliability in demanding grow environments. Photophyll™ Select options in the JB3030C and 2835 platforms deliver industry-leading efficiency with excellent sulfur resistance and footprint compatibility with 301B/H devices - making design-in seamless for horticulture luminaires. The 2835 N-Class color portfolio adds even greater flexibility with 15 high-efficacy spectral options that support precise spectrum tuning. For high-power applications, the JR5050C provides the industry's highest efficacy in its class and can reduce system costs by up to 40%. The JR5050B complements this with best-in-class efficacy in both 6V and 30V configurations. The J Series portfolio also features top-performing white LEDs. The JB3030C delivers up to 3.33 PPF/W (typical), while the JB2835B offers the highest efficacy available in a 2835 white platform. Together, these solutions give horticulture lighting manufacturers exceptional efficiency, broad spectral versatility and unmatched design flexibility.
