Nanometer Specific Fluorescent Grow Lights

Certain fluorescents even provide narrow spectrums of light—focused in the upper red, blue, pink, and even green spectrums—plus UV radiation. These narrow-spectrum fluorescents allow you to easily trigger or maintain specific growth and development phases.

I mix different color spectrums with different lamps in this large T5 fixture, depending on which plants I’m growing.
