The Growers Choice 4K 630W refers to a complete horticultural lighting fixture utilizing two 315-watt Ceramic Metal Halide (CMH) lamps to achieve a total output of 630 watts. This system is engineered to replicate and harness the powerful, penetrating light of the sun, making it an ideal solution for all stages of plant growth, from seed starting and vegetative development to flowering. The 4000K color temperature provides a balanced white light spectrum that supports vigorous plant development and can promote enhanced resin production due to its specific UV output. The system incorporates advanced features such as Smart Start Ignition Control, which ignites lamps one at a time to prevent electrical surges, and Soft Start Technology to prolong lamp life by gradually increasing current. 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.
