The growth and development of plants requires light waves in specific parts of the spectrum at various stages of growth. The Horticraft Holland frequency range provides the desired wavelengths for the vegetative phase of plants. Wavelengths range from 430 to 780, and peaks in the Blue region of the light spectrum. Blue light is usually referred to as part of the light with a wavelength of 400-500 nm that is directly related to the production of chlorophyll. This wavelength band is within the visible light spectrum. It has a relatively high energy and has a significant effect on plant vegetative growth and flowering. Plants that grow in sufficient blue light have strong and healthy stems and leaves. From an energy efficiency standpoint, blue light appears to be less efficient than green or red photons due to the underutilization of high energy. However, for normal plant growth, minimal intensity blue light is essential for most indoor lighting applications. In addition, blue light is involved in the regulation of stomatal opening, which is a small plant organ in the leaves that controls both water loss and CO₂ uptake. FREQUENCY can reach a light energy utilization of 80%-90% and the energy saving effect is very large.

FREQUENCY can be used in fields such as greenhouse light supply, tissue culture, sapling cultivation, and plant factories. It is a ideal LED grow light for indoor growers with a 150cm x 90cm or 5ft x 3ft coverage. With a full power of 240W, it can deliver PPF of 665 μmol/s with an efficiency of up to 2.8 μmol/J. The light source consists of high efficiency LEDs with a spectrum of 5000 K, which is well-balanced and suitable for the entire growth cycle from propagation to flowering. Blue light promotes the rapid growth of strong stems and compact size microgreens during the vegetative stage and is ready to bloom at its best. Red is the main light spectrum used for photosynthesis. Red light promotes leaf area growth and is required during the flowering period of the plant. Blue light is suitable for vegetative growth, promotes weight gain of stems and leaves. The effect is enormous and the growth rate with FREQUENCY is almost three times that of naturally growing plants. FREQUENCY comes with a 5 years warranty and the approximate lifetime of 50000 hours for this type of LED grow light.
