Why the Quantumlink

Precision light measurement for your canopy.

Without accurate light data, growers risk uneven canopy coverage, wasted energy, and inconsistent yields. The Quantumlink delivers full-spectrum PAR measurement so you can optimize every fixture and maximize every photon.

Full-Spectrum PAR

Accurate PPFD measurement across 400-750nm for LED, HPS, and mixed lighting.

DLI Tracking

Daily Light Integral calculation for consistent light delivery across cycles.

Canopy Mapping

Identify hot spots and dead zones to optimize fixture placement.

Multi-Metric

PPFD, Lux, color temperature, and flicker frequency in one sensor.

Energy Optimization

Right-size your lighting output and reduce energy waste.

Growlink OS

Continuous monitoring and logging through the Growlink platform.

The Growlink LINKS System

One sensor. Complete light intelligence.

The Quantumlink connects to your LINKS ecosystem through a canopyLINK or HUB — feeding real-time light data into Growlink OS for automated monitoring, alerts, and optimization across your entire facility.
