Violet-blue light offers a light in the 400 - 520 nanometer range that encourages chlorophyll absorption, photosynthesis and growth.luorescent grow lights have a low heat signature and produce a decent spectrum of light for growing. Tube lights or compact fluorescents in a reflector are both available. Lifespan averages 10,000 hours. LED grow lights offer the latest technology on the market today.
