Cool & Warm Spectrum Fluorescent Grow Lights

Some fluorescent grow lamps are available with spectrums weighted to specific color ranges, such as red or blue.

Fluorescent grow lamps are available in distinctively warmer spectrums, as well as full-spectrum forms that provide a better balance of light across the entire PAR light spectrum, which allow you to grow plants more effectively through their vegetative and flowering phases.
