Grow Light: Artificial Lighting for Healthy Plant Growth
A grow light is an artificial light source designed to stimulate plant growth by emitting an appropriate spectrum of light that plants need for photosynthesis. These lights are widely used in indoor gardening, hydroponics, greenhouses, vertical farms, and research laboratories, where natural sunlight is limited or unavailable.
Grow lights allow growers to extend the growing season, control environmental conditions, and optimize crop yield and quality.
How Grow Lights Work
Plants absorb light primarily in the blue (400–500 nm) and red (600–700 nm) wavelengths. Grow lights are engineered to emit these wavelengths, either selectively or as part of a full spectrum, to support different stages of plant growth:
Blue Light – Encourages vegetative growth (leaves, stems).
Red Light – Promotes flowering and fruiting.
