The Grower's Choice 6K bulb is the best bulb for plants in the vegetative stage. The 6K lamp emits a cool blue light, matching the color of sunlight in spring time. This color of light typically encourages short inter-nodal spacing and bushy plants.

• Mimics spring time light, promotes short inter-nodal spacing
• High quality quartz glass for consistent spectral output and PAR production
• Great for commercial applications where a large vegetative footprint is desired
