It is not a magic wand. Just a smarter one.
The optimal method for measuring fractional PAR (photosynthetically active radiation) is with the LP-80 ceptometer. It is a very accurate way to determine canopy growth and canopy light interception, as well as calculating fractional interception and crop coefficient. And because the methodology is automated, it saves you intensive manual work and saves you time. The low cost of the LP-80 also keeps your entire budget from going up in smoke.
