When you switch to 100 percent light

At what week of bloom do you all switch to 100 percent light? Here are my plants… At 75 percent light
… should I flip to 100?

They look happy at 75%, 100% might be too much. I’d download the photone app on your phone and measure what your getting at the canopy.

Start using DLI

Daily Light Interval (DLI) is a quick and efficient way to calculate how much light our plants are receiving within a 24hr period, allowing for easy light adjustments. DLI will help you and the community to better understand your lighting in a more universal term, leading to clearer communication of what the true light value is. Almost all smartphones have the ability to use an app (we will get to this don’t jump the gun) in order to calculate DLI, and if that is not an option a cheap LUX meter…

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]
