Sylvania GRO-LUX Aquarium fluorescent lamps provide the essential energy for use in indoor gardening applications. Light provides the energy that plants need to produce food and other substances required for growth and flowering. These lamps provide the types of light that are most beneficial for these essential processes.
GRO-LUX Aquarium lamps provide the right balance of red and blue wavelengths for low-energy plants such as house plants. High energy flowering plants require more energy in the red portion of the spectrum. Photosynthetically Active Radiation (PAR) varies according to the cultivar grown.
In addition to providing essential energy for growth and maintenance, GRO-LUX lamps bring out the vibrant natural colors of the foliage, flowers and vegetables enhancing their appearance.
Lamps shall provide the red and blue wavelengths of energy needed for photosynthesis and chlorophyll synthesis in plants and in general, provide the light needed for plants to flourish and look their best.
