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
