Sun White Spectrum

The spectrum that started it all and can grow almost anything is a full-spectrum light formulated to mimic natural sunlight conditions and is ideal for every stage of plant growth. High CRI 95 light accentuates plant coloration and makes visual inspection easier. Includes 660 nm (red) and 730 nm (far-red) wavelengths to boost photosynthesis rates via the Emerson Effect.
