GG 900W 4-Channel LED Grow Light
Designed for growers who demand full control, the GG 900W features four independent dimmer dials—each adjusting a dedicated bank of diodes: Veg (5000K), Bloom (3000K), IR (660nm + 730nm), and UV (395nm). Fine-tune your spectrum for every stage of growth without swapping lights or adding boosters.

Advanced Spectrum Control with Smart Timers
Pair with the Gambit Master Controller to schedule each channel individually. Run UV for just a few midday hours, scale back IR during veg, or boost it during flower for enhanced bloom. The sunrise/sunset function gradually fades lights on and off, reducing stress and mimicking natural light cycles.

LED Star Diodes (Seen on Many Grand Master Lights)
Powered by high-efficiency LED Star chips—used in many Grand Master LED fixtures—this light combines 3000K, 5000K, 660nm, 730nm, and 395nm to deliver a full-spectrum output optimized for vigorous growth, terpene production, and heavy yields.

High PPFD Across a 5x5 Canopy
The 8-bar layout floods your grow space with uniform PAR, ensuring deep canopy penetration and even coverage from corner to corner.

Durable, Silent, and IP65 Rated
Built with passive cooling, no moving parts, and a rugged aluminum housing, the GG 900W thrives in high-humidity environments. IP65-rated for moisture resistance—perfect for tents or commercial rooms.
