Of course it will work,just as fine as from a datasheet!Of course, no rush

Will something like this work for digitizing?

1 square meter = ~9 square feet ....
I 'm really leaning towards the assumption ,that no more than 10-12 CXAs(of the above case ) should be used ,LOL, I meant 1 square foot of course. I am not use to this measure but more to the square meter so it come naturally
Though I would love to have a big 400W cxa at 40% of efficiency in da house
A meter square to power would make about 1200$ for the light then. The price really begin to get down
Btw, the seed we grow are generally selected in europe or America where the sun is less powerful. Perhaps by doing the selection the one which performed the best where the one needing less light and so we kept them.12 hours of constant (high) irradiation ,does not happen nowhere upon
the planet Earth.Is Abnormal situation ....
Well, here I have to say indoor is abnormal so no problem for me. The soil pot are abnormal, the areo/hydro CO2 supplement are all abnormal. It does make a different weed but doesn't matter to me.
Spring/Autumn at Equatorial zones ,might resemble that a bit ,but irradiance still is not constant from
8:00 am to 8:00 pm for example ...
While on a grow tent it is ....
Where I lived, for a practical experimentation in my studies we had a device (can't remember it's name lol) to calculate the irradiance. At the sun highest intensity time (around mid day), we where at 900W/sq meter. I am sure of this value btw. When some clouds appeared it was more light 400W/sq meter. And I said to myself, indoor is 400/600W per m2 all the day while the sun is on average 500W at the peak of the day. I personally prefer indoor weed and I understood why at this time.
Summertime ,close to North pole (*for the nothern Hemisphere ) ,Sweden let's say ..
Daylight lasts for almost all day long ..close to 24/24 ...With almost constant irradiance..
But irradiance is way low ...At average ~400-600 umols/sec (-900 umol/sec max noon peak )
Comparing to i.e Hellas,with a sunlight of average 1000umol/sec ( ~2000umol/sec noon peak) power and a duration of ~14 Hours ,at same time of year.
A 12 hours light regime ,under constant & high ( >1000umol/sec ) irradiation, is actually "overdriving" the photosynthetic systems of most plant species .
I live in europe, and I go north of africa every year. I learned to grow there with family, I have grown some myself. I can tell you something : the average there is not 900W/sq meter at mid day, in sumer I remember once a temperature of 52°C (taken under sun so not really accurate but at least 45°C in the shadow). The canna can flower almost at any period of the year overthere and the bud are much much better than any indoor grow or european outdoor grow if done by yourself. (in my opinion)
I guess same thing is happening in Afghanistan or Mexico. And canna is natural in these country it is a real weed in the proper sense of the terms. So It is use to this amount of light.
All this to say: I think you can go at more than 450W PAR /meter.
The only thing is there is no point in term of efficiency in indoor...
so @1400mA 10-12 pieces of AB bins per 1 square meter of leaf canopy area(ideally) ,
might be more than enough actually ..... Here I totally agree with you. Indoor and outdoor are different especially since we have no dimmer to imitate the amount of light increasing yet (I saw your thread and your idea is definitely possible look at aquarium light

Any links to sources of those graphs ?
We'll soon see.
Would that still hold true for high tech gardeners that use non-organic hydro and CO2 supplementation?
