Light intensity during flowering

[Dave101]

Photone app vs apogee meter.

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 [image] Get a reading of 1297 [image] Will place phone at same location with diffuser [image] With diffuser removed [image] Pretty close, had similar results in the veg tent. Apogee showed 321 at plant tops [image] Photone with diffuser [image] Without diffuser [image]
