Growlink Quantumlink

Accurate full-spectrum PAR data.

Any light source.

Light drives yield, quality, and efficiency.

Too little, and plants stall.

Too much, and you waste energy or stress the canopy.

Quantumlink gives you precise, canopy-level insight so lighting decisions are based on data, not guesswork.

Dial in your lighting Measure PPFD across the canopy and track daily light exposure over time to understand uniformity, intensity, and consistency across rooms and zones.

Fine-tune fixture placement and layout Identify uneven canopies faster Reduce wasted energy without sacrificing yield Reliable data from any setup Quantumlink measures the full range of photosynthetically active radiation plants actually use, delivering spectrum-correct readings regardless of fixture type.

LED, HPS, metal halide, or mixed lighting Consistent results across different spectra Confidence when comparing yield vs energy cost Because different fixtures emphasize different wavelengths, spectrum-correct sensing matters.

Quantumlink gives you the full picture so you can confidently adjust intensity, duration, and strategy across veg, flower, or mixed rooms.
