I’m talking about LEDs specifically.
It’s just a dance I don’t want to do. X power at X distance which needs to change based on height so do I raise the light or fiddle with the dimming?” I choose to move the light. It’s just easier on my brain.
18” full power is good for veg and 12” for flower. For me anyway.
You’ve chosen the opposite which is to have static lights and adjust power which is fine too it’s just not the way I do it.
