You lost me on DLI , it measures how much per day ligh cycle. I don't under stand that lol.Lux is just another form of light measurement .
PAR rules for plants .
The VPD is part of how the plant survives .
The charts represent levels to keep your plant happiest .
DLI is like a rain gauge for light . It measures how much per daylight cycle .
Always best to learn the light without a meter. Meters are best used to even distribution.You can do a LUX to PAR conversion if your light matches one of the presets

But I think you are wasting your time chasing this with a 240W LED light. You can go full blast at 18 inches for 18 hours a day during veg. 12-18 inches for a 12 hours during bloom.
Ok Thanks I'll read into this now lolDaily Light Integral Daily light integral (DLI) is the amount of PAR received each day as a function of light intensity (instantaneous light: μmol·m-2·s-1) and duration (day). It is expressed as moles of light (mol) per square meter (m-2) per day (d-1), or: mol·m-2·d-1 (moles per day). The DLI concept is like a rain gauge. Just as a rain gauge collects the total rain in a particular location over a period of time, so DLI measures the total amount of PAR received in a day. Greenhouse growers can use light meters to measure the number of light photons that accumulate in a square meter over a 24-hour period.

I do have 4 of them, 240x4 leds over 8 plantsYou can do a LUX to PAR conversion if your light matches one of the presets

How big is the tent?I do have 4 of them, 240x4 leds over 8 plants
2m tall, 2m wide left to right ,How big is the tent?
