Information

Far-red light (>700nm wavelength) is at the very edge of the photosynthetically active radiation (PAR) and visible spectrum, and falls outside the PAR range of 400-700nm.

 

Different wavelengths of light have different photosynthetic efficiency, peaking in the red and blue regions. Although photosynthetic efficiency falls sharply for wavelengths longer than 685nm, far-red light enhances the photosynthetic efficiency of shorter wavelength light.

 

Delivering far-red light to the crop at certain times allows growers to manipulate plant responses, flower faster, and boost yield. HIGH GROW LIGHTs platform is built to help growers leverage far-red and intelligent lighting control.

 

For example one of our grow light SHINE series modular led grow light has equipped withFar-red high efficacy led chips, help the plants has better performance in boosting and flowering stage.

 

 

FAR-RED LIGHTs PROFITABILITY When Planting

 

  1. GROW CROPS FASTER

 

Far-red light, delivered only at specific times of the day, acts on photoreceptors in short day flowering plants, accelerating flowering and ultimately reducing time to harvest.  

 

  1. BOOST PHOTOSYNTHETIC EFFICIENCY

A small absolute quantity of far-red light delivered during the day can boost the crops ability to metabolize with PAR spectrum light in the 400-700nm range. We typically see about a 10-15% increase in yield between light formulas with and without far-red light.

 

  1. MANIPULATE CROP RESPONSES

Fine tuning the ratio of red to far-red light allows growers to induce shade avoidance responses in the crop, which can be used to boost leaf area and radiation capture in the earliest stages of growth.
