The Grower’s Choice 6K 400 W SE Veg is a high-quality single-ended metal halide lamp designed specifically for the vegetative stage of plant growth. Emitting a crisp 6000 K spectrum that closely resembles cool spring sunlight, it promotes vigorous, bushy development by encouraging short internodal spacing and dense foliage. With pulse-start technology, it delivers reliable performance and uniform light output, making it well-suited for both hobbyist setups and commercial grow rooms. The bulb is constructed from premium quartz glass, ensuring stable spectral output and ample PAR throughout its lifespan. It holds onto roughly 90 % of its initial light output even after 5,000 hours of use, reflecting a long service life and helping reduce replacement costs. But if this lighting system is too powerful for your grow space, then take a look at the ROI-E420 system, or the smaller 10K 1000W SE for better light management.
