Your 1300 par reading sounds right. The par is calibrated for indoor light. It's the beginning of spring. You should get 1800-2000 at noon around July, remember the earth is on an axis.


I'll try a different light source next round just to make sure. I have a feeling it's slightly high but x2 or x3 is too much. Again, if you feel it's too much, change the pot to your liking.

This meter pegs out at 1391 no matter how bright it is outside. Readings are two to three times greater than what a real par meter is showing me. Buyer beware, this meter is not legit. Sorry bro, I gave you a chance to come correct and you failed.
