The Grower’s Choice 3K 1000W DE CMH is a double-ended ceramic metal halide bulb engineered to replace traditional 1000 W HID fixtures with a cleaner, more efficient technology. Emitting a warm 3,100 K full-phase spectrum, this lamp is optimized for bloom while also being perfectly capable during vegetative growth. It produces rich red and far-red wavelengths with added UV and a precise blue component, closely mimicking natural sunlight and stimulating stronger metabolic activity and resin production versus typical HPS options. Designed for commercial environments, the lamp packs around 2,050 µmol/s of photon flux, about double the output of Grower’s Choice’s 500 W CMH, and maintains a high Color Rendering Index of 90, delivering brighter and more natural-looking light. 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.
