The GrowLight Quattro series was developed with a balanced light spectrum. The LED chips generate the optimum wavelengths that stimulate photosynthesis and chlorophyll formation the most. White full spectrum light stimulates root growth. Blue wavelengths stimulate leaf growth. The red wavelengths ensure stronger shoot and flower growth and prolong the flowering phase. They are usually used together with the blue/white wavelengths to stimulate plant growth as a whole. In combination, the plants will always grow in a good ratio of roots to shoots and leaves. Well-matched light wavelengths that are suitable for a wide range of applications. The GrowLight-Quattro can be used for growing and forcing plants or as a light supplement in dark rooms/greenhouses. It is also suitable for overwintering citrus fruits and succulents during the cold season, for example. Thanks to the harmonised wavelengths, the GrowLight-Quattro can also be used for growing in rooms without any daylight at all. An integrated control unit allows the blue/white and red wavelengths to be controlled and dimmed individually in order to have the best possible effect on different growth phases. A timer is built into the device (35W only). The GrowLight Quattro strips are available in two versions (35 W and 60 W).
