LED grow lights deliver targeted, high-intensity light and are ideal for growing plants and vegetables indoors and in confined spaces. LED lights provide portions of the light spectrum plants need to thrive at different stages of their life and are made to last 50,000 to 100,000 hours.
All Blue Grow Light Panel
The most popular and recommended light for all-purpose growing is the blue LED light, which stimulates chlorophyll production more than any other color in the spectrum, "promoting thick leaves, stocky stems and strong vegetative growth," according to superiorgrowerssupply.com.
Blue LEDs run at a cooler temperature than other plant lights. "This more controlled running temperature reduces the need to water so often and keeps rooms with plants from getting uncomfortably hot in the summer months, requiring additional air conditioning," according to LEDwholesalers.com.
Mixed LED Grow Lights: Blue and Red
Blended LED systems combine blue and red lights to produce lush vegetation, promote flowering and can be used for spring vegetable and flower seedling development, according to davesgarden.com. Designed for use year-round, the mixed panel provides "even blending" of light wavelengths, eliminating the need to reposition panels "to achieve uniform exposure."
Red LED Grow Lights
Red LED light stimulates vegetative growth and flowering, according to gardeners.com, "but if a plant gets too much red light, it will become tall and spindly." Typically red LEDs are combined with blue light for balanced growth, but horticulturists have used red exclusively in short durations to stimulate flowering, seeding and fruiting when plants are under-producing.
