What lux do you run at in veg and flowering in tent?

[the123321]

I plan to try the Dr.meter Professional LED Light Meter to measure the lux of a 240w kingbrite led quantum board in a 32x32 tent. The temperature in tent is like 77-81f with around 50 - 60% humidity in the tent.

I have read different numbers on different websites. What lux do you run at in veg and flowering on there?

From what I understand Lux is measurement of light visible to the human eye. Our cannabis plants light usage is measured in PAR or PPFD.
There is an equation to get a guesstimate of PAR using a LUX meter and white light.
Your kingbrite in a 3x3 should be 737 uMol/m2/s @20" height.
There is a quick read here that can explain more than I can

Maximize Cannabis Growth @ 700, 1,500 or 2,000 µmol/m2/s? And, What About CO2?

Words and images by @SuperFunker. How 'high' must Photosynthetic Photon Flux Density (PPFD, µmol/m2/s) be to induce peak photosynthesis in Cannabis? In 2008, Chandra measured a maximum rate of photosynthesis at 1,500 µmol/m2/s. In 2015, Chandra conducted a similar assessment and measured a...

I was just reading this page earlier trying to figure out why my light turns plants purple at a certain distance away. Has something to do with Anthocyanin in the plant and light spectrum.
