Results are in, I was impressed with the Photone app, pretty close to the Apogee when a diffuser is used, totally wack without a diffuser.
Starting with the Apogee SQ-626 in the flowering tent
Get a reading of 1297
Will place phone at same location with diffuser
With diffuser removed
Pretty close, had similar results in the veg tent. Apogee showed 321 at plant tops
Photone with diffuser
Without diffuser
