Measure the Light
That Matters…

Plant growth and reproduction is driven by photosynthetically-active radiation (PAR), which occurs at wavelengths between 400 and 700 nm. Not all sources of light deliver equal light intensity across this range, and proper understanding of the PAR profile of your greenhouse or growth chamber is the key to controlling critical parameters of plant growth and reproduction:

  • Photosynthesis and photoperiods
  • Water and nutrient efficiency
  • Flowering conditions
  • Plant stress

Different plants have unique PAR requirements based on growth stage and type, and a sensor that over- or under-estimates PAR could result in the application of too little or too much light intensity. The LI-190R Quantum Sensor, included in the LI-250Q package, provides uniform sensitivity across the PAR waveband, delivering the most accurate PAR profiling of any sensor on the market.

…No Matter the Source

Optimizing light for efficient greenhouse or growth chamber production means knowing when and how to use artificial lighting to supplement sunlight.

The LI-190R Quantum Sensor measures PAR with the same precision in sun, artificial lighting, or a mixture of the two. Compatible artificial sources include incandescent and high-pressure sodium lamps, high-intensity fluorescent lights, and the rapidly emerging range of LED light systems.

Most importantly, the LI-190R measures PAR down to the nanometer in a mixture of light sources without recalibration or changing multipliers. No other sensor on the market provides a comparable level of precision or adaptability to varying ratios of natural and artificial light.

Grow Confidently

The LI-190R Quantum Sensor is built upon 40+ years of LI-COR light measurement experience with sensors optimized for unprecedentedly accurate PAR measurement. LI-COR instruments have been featured in thousands of peer-reviewed publications, and we have built our brand around scientific partnership.

We’re excited to extend this partnership to commercial greenhouse and growth chamber operations.
