What is Dual-Channel technology?
HortiSpectra lamps are equipped with an advanced technology called Dual-Channel, which allows you to independently control two distinct light channels:
Channel 1 — Full Spectrum: broad-spectrum white light, ideal for the vegetative phase and general growth
Channel 2 — Red + Far Red + UV: spectrum enriched with specific wavelengths to stimulate flowering and improve crop quality
Thanks to two independent dimmer knobs, you can adjust the intensity of each channel separately, creating the perfect light combination for each phase of the culture cycle.
Why is it important to control the spectrum?
Plants don't need the same light throughout their lives. Just as in nature sunlight changes with the seasons, even in indoor cultivation it is essential to adapt the light spectrum to the growth phase.
Always using the same light throughout the cultivation means not taking full advantage of the potential of your plants. Spectrum control is what distinguishes an amateur grower from a professional one.
How to use Dual-Channel in the vegetative phase
During the vegetative phase, plants need white light rich in blue and green to develop healthy leaves, robust stems and a strong root system.
Recommended setting:
Full Spectrum Channel: 80-100%
Red + Far Red + UV Channel: 20-30%
This combination favours compact growth, dark and chlorophyl-rich leaves, and a robust structure ready for flowering.
How to use Dual-Channel in the flowering phase
When plants enter the flowering phase, they need more red light and colour red to stimulate the production of flowers and fruits.
Recommended setting:
Full Spectrum Channel: 70-80%
Red Channel + Far Red + UV: 80-100%
The increase in the Red + Far Red + UV channel stimulates the production of larger, denser and richer in active ingredients flowers, significantly improving the quality and quantity of the crop.
The role of Far Red and UV
Channel 2 of HortiSpectra lamps includes three specific wavelengths:
Red 660nm: the peak absorption of chlorophyl, maximum photosynthetic efficiency
Far Red 730nm: activates the Emerson effect, increasing the overall photosynthetic efficiency and accelerating flowering
UV 385nm: stimulates the production of resins, terpenes and anthocyanins, improving the organoleptic quality of the crop
Conclusion
Dual-Channel technology is not just a dimmer — it is a professional tool that allows you to customise the light according to the real needs of your plants, phase by phase, species by species.
With HortiSpectra lamps you have total control of your crop cycle, from germination to collection.
