The last I read from Finnex, the reason for no PAR data on the Planted+ is that the person/company they relied on to do their PAR testing is no longer doing that. They were looking for someone else to do it at that time - a few months ago.

Finnex PAR data was measured with the LI COR PAR meter, which does measure the red light that is within the 400-700 nm spectral range for PAR. It is the Apogee Quantum PAR meter that misses some of the red light near 700 nm.
