Recommended lux during plant life cycle?

[niv141]

Im rather confused.

A post on reddit from a reputable person (SuperAngryGuy) says he recommends

5000-7000 lux_______cloning and seedlings
15000-20000 lux____ the lower end of what we want for veg growth
35000-40000 lux____ what we want to try to hit for flowering
75000 or so lux_____ it's pointless to go beyond this level of light intensity, saturation level

and yet there's this website that recommends different figures

< 15,000 lux – sparse or “stretchy” growth – plant isn’t getting enough light
15,000 – 50,000 lux – good amount of light for healthy vegetative growth
45,000 – 70,000 lux – optimal amount of light for cannabis plants in the flowering (budding) stage
70,000 – 85,000 lux – a lot of light, some strains thrive at this light level
> 85,000 lux – at this light intensity, you’ve hit the plant’s “saturation point” which means your plant can’t use all the light

I think you are confusing lux for color temperature.

5000-10000 lux ____ cloning and seedlings
15000-20000 lux ___ the lower end of what we want for veg growth
25000-30000 lux ___ for optimal veg growth
35000-40000 lux ___ what we want to try to hit for flowering for a high g/kWh ratio
50000-55000 lux ___ what we want to try to hit for flowering - the golden mean
65000-70000 lux ___ what we want to try to hit for flowering for a high g/m² ratio
>70000 lux ________ pointless to go beyond this level of light intensity -> saturation level (w/o CO2 and below a certain leaf temp.)

For your average warm white led: those first numbers are right. We veg softer though, at around 10000lux. But youre better of with measuring PAR/ppfd as it is a more absolute reading, lux depends mainly on how much green light you have in your spectrum.

Can u elaborate a bit on the flowering part?
the g/kWh ratio, golden mean, and g/m2 ratio. Having a bit of a hard time understanding those
