no the sun produces a high of like 1100 psf but not every day and thats only at its peak, than theres clouds and trees, seasons\ angle and other things that subtract from itThe sun gives off almost 2/3rd more light than a 1000 HPS. Right? Well doesnt matter, the sun has way more lumens than a 1000 watt. I guess Im not understanding.
it gets brighter all morning until it peaks than drops off.. in a 4x4 room with 1000 watts thats like 140000 lummens devided dy 16 sq ft=8750psf
so its not too extreme but it is a lot and if your entire environment isn't right on than it can only use so much than it starts converting it too heat and solws photosynthesis
unless you have co2 i wouldn't go over 7000 lumens psf with co2 10,000
my buds grow big and dense with just over 5000 psf
