UVB is most beneficial for flowering and that is a range of 280-315nm. And UVA which is best during vegetative growth is 315-400nm. So it will barelyyyy measure any UV at all actually. Tricky marketing tactics. But still the best on the market, hopefully they can further increase the range of measurement in a newer model! ### ⭐⭐⭐⭐⭐ Can't beat industry leader in PAR Meters *by J*** on December 27, 2020* Apogee quality quantum sensor delivers extended range readings of PAR vs cheap lux meters. This is what you need to dial in your system.
