The Cheapest LED Grow Lights

Light Emitting Diode grow lights (LEDs) are a long-lasting, durable light alternative for growing plants inside. LEDs do not have a filament, so they are not easily damaged like incandescent lights. In addition, they are solid and not as fragile. LED grow lights do not heat up like incandescent bulbs and use between 2 and 10 watts of electricity. Because they are mercury-free, recycle led grow lights for sale after they burn out.
