What type of light is best for growing plants indoors?
LED grow lights offer the latest technology on the market today. Extremely energy-efficient, they have an ultra-low heat output and offer an ideal light spectrum range. Offering low energy usage, low heat, and color optimized for growth, LED lights are the most efficient, effective, and customer-friendly way to grow plants at home than growing with fluorescent lights or incandescent lights.
High-Intensity Discharge or HID bulbs produce light through an electric arc between tungsten electrodes inside a tube fused with alumina. These specialty bulbs have a very high light output level and are commonly used by commercial growers.
Metal Halide lights use mercury vapor mixed with metal salts to create a powerful light source. They use a special fixture and, like HIDs, are commonly used by commercial outfits.
