GrowRay Adaptive Controllers serve to optimize lighting throughout a greenhouse. Each luminaire has its own sensor, effectively providing plants with their own “light meter.” If a particular section of a greenhouse is shaded from the early morning sun, GrowRay’s grow lights with Adaptive Controller will automatically adjust to provide the plants with the ideal level of light. At the same time, ​lights on the eastern side of the greenhouse would be dimmed or turned off. This reduces energy consumption and provides every plant the correct PAR at all times.

GrowRay’s Adaptive Controller adjusts light intensity in real time based on available sunlight. If full sunlight is available, GrowRay grow lights are automatically turned off. When available sunlight is diminished, the lights are turned on in a linear fashion, with just a little supplemental light output for a passing cloud, to full on for a rainy day, or short winter days. Adaptive Controller automatic dimming thresholds are factory set to begin adding supplemental light when measured sunlight levels fall below 900 PAR. GrowRay Adaptive Controllers thus provide plants with the correct light level for optimal growing results.

“We added GrowRay supplemental lights to our existing grow. We determined that adding additional light and adjusting our pruning to take advantage of it has increased dry weight per square foot between 10% and 30%, by improving growth and density of the flowers. The flowers also showed visibly increased trichomes. In addition to the additional dry weight and trichome production, another great benefit is that our bloom cycle has been consistently reduced by up to 7 days, translating into additional output per square foot annually.
