We have Red & Blue LED Grow Lights Panels for sale at cheap prices.
Scientifically calculated even blending of red and blue LEDs eliminates the time consuming task of repositioning separate colored lights back and forth trying to achieve uniform exposure. 14 to 16 hours per day is all that is necessary for maximum plant health with this wave blended lighting system. This allows distances 4"-8" and less between the LEDs and the plants accelerating photosynthesis. Red and blue wave lengths are for growing and flowering of plants. The purity of the LED generated light lengthens flowering periods.
