Calm down a little, admittedly they didn't lay it out...Par or PPF is the measure of all light [photons:radiometrically] per second umol/s, PPF/D is in a Square meter of space but the same umol/s^2.....A single reading like you mentioned doesn't account for all photons per second of that fixture, just a narrow area where those diodes may be more powerful than say diodes on the outside that aren't measured in the "spot" reading..., so it is completely innacurate and would be also technically different for Kelvin temps as Blue waves give off more photons per/w than Red waves, so we need an accurate way to determine ALL light.....does that make any sense?
This method is used for all types of light, not just LED's.........
Yeah, i understand that. Alllll im saying is, he took the same points measments from areas on the floor for each light. Center, 1ft out 2 ft out from all sides. with the same meter. and the PSGoliath did better then the 1000w by 60 average PAR.
Yes, the goliath does have more greens and yellows, so yes, it will register a higher number somewhat, but in the realm of things, the plant uses those colors, where-as the 1000w HPS doesnt even have those nms to begin with. It has no green, which is proven to be needed from the plant for better CO2 uptake and such.
So, in a sense, Neils spectrum is superior to the 1000w just in that retrospect alone. The center par value almost doubled that of the 1000w. and still carried 35-40% higher to the edge of the footprint.
*shruggs, IDK bro, Its not really that big of a deal.
At the end of the day, you can use shit genetics, shit products, shit atmosphere conditions, shit water, shit timing, and NEITHER will produce well, agreeable?
and, ive seen readings from 1000w HPS, the par drops off considerably past 24inches, where as Neils lights dont.
Ill tell ya this. I have great genetics (Fire OG), great Nutes (megaCrop), "great"light (PSmini), in coco, in a 2x2 and I bet I pull 2:1 with this light.
