655W in 3x3 or 4x4?

ppf is a fixed number, it's always the same amount...

You should call Fluence a Osram company and tell them they dont know what they are talking about.

PPF is not PPFD.

You need higher temps. I run 84-86 @60% humidity. Clear through. Start to chop. If I drop below 77° they get all droopy. Atleast in my experience. But you def need to be above 80° with strips.

I showed how to calculate PPFD from the PPF numbers in my first post. Not going to make a difference the further the light sensor is from the LED the lower the PPF readings then doing the math to calculate PPFD will show it gets weaker the higher the light.

PPF is a constant as @sethimus stated - it is a measure of the total amount of PAR - not weighed by a distance variable. Your sentiments undermine the very unit of measure.

I run 660w of strips in a 2x4 and 575w in 32x32.
Flowers the fuck outta both.

More in the 8sq ft than the 9!!!

LOL. 32"x32" is 7.111111111111111 square feet.

ppf is the total output of a lamp. ppfd is the total output of the lamp over an area. why is that so hard to understand? ppf can only be measured in an ulbricht's sphere. now go weep in a corner, loser

People can disagree, but the rage and swearing tends to leave them ignored.
