It's not that simple...While it's true the plants use a lot of blue and red, the plants need a broader spectrum of light than just red or just blue. They also use different wavelengths for veggin vs. flowering. You can't hardly beat the spectrum of an MH bulb for veggin and an HPS bulb for flowering tho. We are experimenting with a new induction light which seems mostly blue and reddish...strange lookin bulb and all!
TANKJR Reviewed by TANKJR on . red or blue uv lights I know that uv lights are made up of red and blue light. Red light is more for growing and photosynthesis, and blue is more for maturity and reproduction. I've heard of people using red lights to make their plants have stronger and stalkier leaves and stems. Would pure blue lights make them mature faster or make the buds larger/stonger? Rating: 5
