Today Ete introduces a very cool lawn tool, Turf Stress Detection Glasses (Turf-Tec) from Turf-Tec International. (Ete has no affiliation with this company and is receiving no compensation from them).

These glasses purport to help you see turf damage, weeds, and sprinkler problems earlier than you would with the naked eye. The technology for these glasses was developed by NASA.   This particular pair costs $35 (Ete's memory was way off on this).

Is this for real? Do they really work? How could these glasses help you? Find out in this Episode of Eco Lawn Science.
