In cannabis cultivation, spectrally balanced lighting is essential for all growth stages. Here are the key points and recommendations for choosing spectrally balanced lighting:
Blue light (400-500 nm): Promotes vegetative growth and makes the plant compact.
Red light (600-700 nm): Promotes flowering and fruiting, and increases yield.
Far red light (700-800 nm): Affects photoperiod and flowering time.
Ultraviolet light (UV-A, 315-400 nm): Enhances secondary metabolites such as THC and CBD.
Full spectrum LED light: Covers all necessary wavelengths, suitable for all growth stages, energy-saving and long life.
Ceramic metal halide lamp (CMH): Provides a balanced spectrum, suitable for vegetative growth and flowering.
Double-ended high pressure sodium lamp (DE HPS): The spectrum is reddish, suitable for the flowering stage, but needs to be used in combination with other lights.
HLG 550 V2 R-Spec: Full-spectrum LED light, suitable for all growth stages, high efficiency and energy saving.
Phlizon CREE COB series: Full-spectrum LED light, suitable for small-scale cultivation.
Gavita Pro 1700e LED: Full-spectrum LED light, suitable for large-scale cultivation.
NanoLux DE CMH 630W: Ceramic metal halide lamp, balanced spectrum, suitable for all stages.
Spectrum coverage: Make sure the light covers blue light, red light, far-red light and ultraviolet light.
Light intensity and uniformity: Choose lights with appropriate light intensity and uniform distribution.
Energy efficiency and life: Choose high-efficiency and long-life lights to reduce long-term costs.
Heat dissipation performance: Good heat dissipation design ensures stable operation of the light.
Vegetative growth stage: Increase the proportion of blue light to promote compact plants.
Flowering stage: Increase the proportion of red light to promote flowering and fruiting.
Full-cycle lighting: Use full-spectrum LED lights to simplify management.
Conclusion
When choosing a spectrally balanced light, you should consider spectral coverage, light intensity, energy efficiency and heat dissipation. It is recommended to use full-spectrum LED lights, such as HLG 550 V2 R-Spec or Gavita Pro 1700e LED, to meet the needs of all stages of cannabis growth.
