The Cluster C4 is the perfect solution for novice and experienced indoor home growers that want to start growing with a high quality and performance, but still affordable LED light.
This Series has been copied, promoted and sold under a variety of brandnames (up to the present day) and not without reason of course, because the Cluster Series already proved itself to be a true HPS replacement and exceeds every other lighting source in its (price)class!
The Spectral output can be adjusted with 3 switches on top of the light: the Vegetative and Flowering mode. The Vegetative mode offers a high Blue ratio with 440nm wavelengths and the Flowering mode offers a high Red ratio with 660nm wavelengths. The COBs offer additional Cyan, Green, Yellow and Orange wavelengths to complement the Spectrum so the C4 provides a Full Spectrum when both switches are on!
Blue wavelengths encourage vegetative growth and are essential in lighting for seedlings and young plants during the vegetative stage of their growth cycle, especially when “stretching” must be reduced or eliminated. It also stimulates the production of secondary pigments which can enhance colors and is known to also stimulate Terpene (i.e. fragrance) production.
Red light affects phytochrome reversibility and is the most important for flowering and fruiting regulation. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production.
