Spectrum and Coverage:
The 720W UnderCanopy LED Grow Light is specifically designed to enhance the flowering stage by delivering a balanced full spectrum that includes red (PPF600-700: 1592 µmol/s) and far-red (PPF700-800: 612.3 µmol/s) wavelengths. These wavelengths are critical for stimulating flowering responses, promoting robust bud development, and improving flower density. The inclusion of far-red light also triggers the Emerson Effect, which boosts photosynthesis efficiency and accelerates bloom cycles. This optimized spectrum ensures more consistent flower color, increased terpene production for richer aromas and flavors, and higher yields, making it an invaluable tool for growers focused on achieving premium-quality harvests during the flowering stage.

FAQs Section
1. How do under-canopy lights with far-red spectrum change the way I grow my plants?
The inclusion of far-red light enhances photosynthesis through the Emerson Effect, which allows plants to utilize light more efficiently. This leads to faster growth, denser flowers, and improved overall plant health, enabling you to achieve higher yields and better-quality harvests.
- Do I need to adjust my feeding or watering schedules with far-red spectrum lighting?
Yes, with increased light intensity and spectrum diversity, plants may require more water and nutrients to sustain enhanced growth and flowering. Monitor your plants closely and adjust schedules as needed to ensure they receive adequate hydration and nutrients.
- How does the far-red spectrum affect flowering and terpene production?
Far-red light encourages more robust flowering by accelerating bloom cycles and enhancing flower density. It also stimulates terpene production, leading to richer aromas and flavors in the final product.
- How much heat do the 720W UnderCanopy Lights produce?
Thanks to passive cooling technology, these lights generate minimal heat, even with far-red output, keeping your grow environment stable and reducing the need for additional cooling systems.
- Can these lights be daisy-chained together?
Yes, you can daisy-chain multiple units depending on your power source and voltage. Typically, 4-6 units can be connected on a single circuit, but always check power requirements and circuit limitations.
- Are the 720W UnderCanopy Lights DLC listed for energy rebates?
Yes, these lights are DLC listed, making them eligible for energy rebates and helping you reduce operational costs while maintaining high efficiency.
- Do under-canopy lights with far-red spectrum increase the risk of plant stretch?
No, the far-red spectrum in these lights is balanced to avoid excess stretching. Instead, it promotes compact, healthy growth by improving light coverage across all plant levels.
- How do I position the lights to take advantage of the far-red spectrum?
Position the lights under the canopy to target shaded areas, ensuring even light coverage. The 24-inch cord length between bars allows flexibility in placement to maximize far-red exposure across all plant levels.
- What maintenance is required for under-canopy lights?
Maintenance is minimal. Wipe down the fixtures periodically to remove dust and debris, and ensure connections are secure for optimal performance.
- How does the far-red spectrum affect environmental controls?
Far-red lighting can lead to increased transpiration and photosynthesis, which may require slight adjustments to humidity and temperature settings. Proper monitoring and airflow management will help maintain optimal growing conditions.
- What is the expected lifespan of the 720W UnderCanopy Lights?
These lights are built to last with an L90 > 5000-hour rating, ensuring consistent performance over years of use.
