Here u go, factors already adjusted in readings.Which subtractions are you referring to? The correction factor was sourced from Apogee's website. BRS doesn't use it because they don't use an Apogee MQ-500 to measure PAR.
Additionally, you can find Dana Riddle's review of it here using the correction factor (and provides comparison data to the Li-Cor).
*The*MQ-210*and*MQ-510*Underwater Quantum Meters already apply the immersion effect correction factor to the meter readings througt the meter firmware. Additionally, the*SQ-420*and*SQ-520*have an "Immersion Setting" that applies the immersion effect corection factor to the sensor readings through the ApogeeConnect Software. These sensors do not need post-measurement corrections applied to their measurements.
I had 3 360s on a 60", had to go to 4 to get coverage. Still wasn't greast down low so went with 2 ap700s.
360s are only really good for about 15" each when doing a lot of sps.
