The GC 4 is a high-efficiency LED grow light perfect for homegrowers with small setups. This compact grow light comes with 4 modular light clusters — each with switchable channels that let you adjust the spectrum based on what phase of growth your plants are in, meaning you get ideal light coverage in both veg and flower. WIth a total power draw of 128 watts, you save energy and keep your operation costs low. Despite its compact design, it produces impressive light penetration and coverage. Equipped with a passive cooling system that keeps noise to a minimum, this plug-and-play setup is ideal for growers looking for professional-grade results in a small homegrow. For those who need more advanced lighting control with optional dimming, check out the upgraded GCx 4 PWR. If you like the design of the GC 4 but need a bit more power, the GC 9 is where it’s at.
