Ok for example; a humidifier which I use in my tent creates water vapour, water vapor affects the intensity of light reaching my plant.
So I can change my growing conditions based on my growing environment.
I can raise my light when I have the humidifier off or I can lower my light when I have the humidifier on.
The amount of water vapour between my light and my plant has an effect on light intensity hitting my plant.
I’m not disagreeing with what light intensity actually is or whether it’s better or worse than Spectrum. I’m saying the growing conditions ‘can’ have an effect on light intensity and the spectrum as a whole… indirectly, not directly.
Hence the reason you shouldn’t be looking just at light intensity or Spectrum on their own. You need to make sure your total grow environment complements each other.
So the question to begin with was kind of confusing or whether it was question at all… more of a rhetorical question🤔
