Spectrum Lighting for Plants

Anonymous added on January 26, 2011 | Answered

I have been told that I should use blue spectrum for vegetative growth and red for flowering. Is this true or is it always better to have more blue light?

Yes, this is true. It is best to have a balance in the spectrum, but a little more blue does help with having a healthy plant.
