Red vs. Blue Grow Lights: When to Use Each Color Spectrum
Red and blue wavelengths (400–700 nm) drive photosynthesis, but relying on them alone often results in leggy growth and reduced terpene production. High-quality harvests require a full-spectrum approach incorporating far-red, UV, and green light to improve canopy penetration and plant structure. Most premium fixtures now integrate these additional spectra to maximize overall yield and potency.
