Still messing around with light height. Second grow with short plants. Could be genetics? Either way, as long as the yield and quality are still good I guess it doesn’t matter!
Photone can be used with a variety of light sources including a few different types of LED.
I've tested Korona /Photone and have traded email with the programmer on a few different topics. My take on it is that, overall, it's safe for a grower to use to get in the ballpark but, if you want consistently accurate readings, use a PAR meter (SPOT ON, LI-COR, or Apogee) is money well spent.
