The Grower's Choice 4K 315W SE CMH lamp delivers a full-spectrum light output tailored for vigorous vegetative growth and excellent overall plant development. With a correlated color temperature of 4200K, this single-ended ceramic metal halide bulb closely mimics natural daylight, promoting tight internodal spacing and robust plant structure. The high Color Rendering Index of around 98 ensures true-to-life color rendering, enhancing visual crop inspection and optimizing photosynthesis across a wide range of plant species. This lamp outputs approximately 535 µmol/s of photosynthetically active radiation (PAR), offering strong intensity for efficient canopy penetration in compact grow spaces. 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.
