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
