Why use red spectrum supplemental lights?

Adding red supplementary light enhances photosynthesis, improves plant morphology, supports flowering and fruiting, and compensates for specific spectral gaps that your main light lacks, ultimately leading to healthier plants and increased yields.

How do I pick the best model for my growing space?
