Start using DLI

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
