5.2 Light Spectrum
The G8600 provides a full spectrum of light, balanced with pure (4800-5000K) and warm (2800-3000K) white light, suitable for all stages of plant growth from seed to harvest. Specific wavelengths contribute to different aspects of plant development:
- Blue (400-500nm): Promotes leaf growth, inhibits excessive stretching, keeps plants compact.
- Green (500-600nm): Penetrates canopy, enhances overall photosynthesis efficiency.
- Red (600-700nm): Increases yield, promotes more flowers and larger fruits.
- Far-Red (700-750nm): Contributes to taller, stronger plants.
