I can't but if you aren't adding CO2 it will be very low.  Also, if you
aren't adding CO2 you might wish to try Seachem Excel as a carbon source for
your plants.  I get growth almost as good with Excel (after building to a
double dose) that I get with pressurized CO2 in a tank with what I would
call a medium light level -- 2.2 wpg in a 55G.  The upside to Excel is no
big upfront costs.  The downsides are that over time it costs more than CO2
and you have to add it daily.  Also, I couldn't say how good Excel does or
does not perform in high light situations except in a nanotank where it does
quite well.
