Underhill - TurfSpy Glasses

How does it work?

Like the technology that makes camouflaged enemies stand out in jungles and forests, our advanced light filtering technology, developed by NASA, turns healthy vegetation dark, exposing plant disease and stress.

Why does it work?

Dying plants signal their distress with changes in how they absorb and reflect sunlight. The earliest signals occur at the outer limits of the human visual spectrum, and are rendered invisible compared to the predominant middle wavelengths. TurfSpy™ Stress Detection Glasses filter the overpowering light in the center so that the fringe spectra, which show early plant stress, become visible!
