Grower's Choice Master Controller

The Grower's Choice Master Controller is a commercial lighting control system engineered to provide centralized management of compatible Grower's Choice LED and HID grow lights. Designed for professional cultivation facilities, it allows growers to automate lighting schedules, independently manage multiple grow zones, monitor room temperatures, and protect lighting equipment through intelligent environmental controls.

Capable of controlling up to 200 compatible fixtures, the controller supports two independent lighting zones with up to 100 fixtures per zone. It is compatible with the entire Grower's Choice ROI LED Series along with GC-315 CMH, GC-630NS CMH, and GC-1000 DE fixtures, making it an ideal solution for commercial flowering rooms, vegetative facilities, and multi-room cultivation operations.

Using its integrated LCD touchscreen, growers can independently program lighting schedules for each zone while adjusting light intensity throughout the day. Built-in sunrise and sunset simulation gradually ramps fixture output over programmable intervals, creating smoother lighting transitions that more closely replicate natural daylight cycles.

The controller includes dual temperature probes that continuously monitor environmental conditions for each lighting zone. If temperatures exceed user-defined thresholds, connected fixtures can automatically dim or shut down to help protect crops, lighting equipment, and the overall grow environment.

Supporting adjustable output levels from 10% to 115%, the Master Controller offers precise light intensity management for both LED and HID fixtures. It also supports multiple ballast configurations, allowing commercial growers to manage various Grower's Choice lighting systems from a single centralized controller.

Designed specifically for commercial installations, the Master Controller supports controller cable runs up to 100 meters per lighting group, dedicated outputs for two independent lighting zones, alarm outputs, and external contactor module connections. Its compact wall-mounted design simplifies installation while providing reliable control across large cultivation facilities.

Powered by the included 5V power adapter, the controller weighs approximately 1.1 pounds (0.5 kg) and includes two temperature sensors, two controller cables, and a user manual. It is backed by a 3-year Grower's Choice manufacturer warranty.

Commercial Lighting Management

Control up to 200 compatible Grower's Choice fixtures from one centralized controller.

Two independent lighting zones allow separate schedules, dimming levels, and environmental protection for multiple grow rooms.

Dual-Zone Environmental Protection

Included temperature probes continuously monitor each lighting zone independently.

Automatic dimming and shutdown functions help protect crops and equipment whenever user-defined temperature limits are exceeded.

Sunrise & Sunset Simulation

Gradually increases and decreases fixture output over programmable intervals to simulate natural daylight transitions.

This feature helps reduce sudden lighting changes while providing smoother daily operation.

Precision Light Control

Adjust fixture output from 10% to 115% depending on the connected lighting system.

Independent programming allows each lighting zone to operate according to its own lighting schedule.

Professional Commercial Compatibility

Compatible with the complete Grower's Choice ROI LED Series, GC-315 CMH, GC-630NS CMH, and GC-1000 DE fixtures.

Designed specifically for commercial grow rooms, greenhouses, and large-scale cultivation facilities.

Touchscreen Operation

The integrated LCD touchscreen provides simple access to lighting schedules, dimming levels, temperature settings, and controller configuration.

Its intuitive interface makes daily lighting management quick and efficient for commercial operations.

Built For Large Facilities

Supports controller cable lengths up to 100 meters per lighting group, external contactor modules, and alarm outputs for seamless integration into professional cultivation environments.
