So I was looking at some kind of Mephisto website, obviously not the USA store website because it’s down, and I saw a listing of the strains. I think this listing was a little bit old, but it kind of laid out the recommended set up for growing each strain for maximum yieldl. The common tent size was 1.2×1.2 m which, according to my stoner math, is roughly a 4x4 in ‘Murican feets. 
The site then went on to say that, for example, with the 24 carat strain, your best yield would come from growing 20 plants in SOG style in roughly 3 gallon pots. Other strains listed set ups of anywhere from that size all the way down to 4 five gallon pots for the same 4x4 setup. When talking about how tall the plants could get, all of the recommendations qualifies this with “Under HPS.“ Herein lies the confusion. A lot of breeders recommendations are based on old technology like HPS lights. Sometimes you see statements like this plant should yield 400 to 500 g “per light“ Precisely what is “a light?“Is it a single ended 1000 W HPS? Double ended 1000w? 600w? Most of the more current recommendations I see for a 4 x 4 tent will tell you to put an HLG 550In a 4 x 4 tent or even a 5 x 5. Those run about 520 W in their competitors can apparently be as low as 480 W. But I also see the new HLG 650 with the Diablo boards being touted as a direct replacement for a double ended 1000 W HPS light and those boards appear to run around 620 to 630 W. Is that designed more for a 5x5? That’s what I’m trying to figure out. A baseline for lighting using modern lights. That way, I figure I can take the recommendation from Mephisto or other breeders, adjust for the light type equivalent, and then just do simple math. If I want to do a 2 x 4, divide the light in half. That would be quite simple with something like an HLG set up. If a four panel 288 llbased light is good for a 4 x 4 than a two panel light will be good for a 2 x 4 in a single panel for a 2 x 2. If a 600-650q is good for 5 x 5, then a 300-320w would work for a 2.5 x 5 and so on But I need to know The original calculations in order to make such conversions and extrapolations. As the French would say, Mercy Bowcups.

What I was trying to find out is what the starting point originally was so I can strip away at least one or two levels of that confusion.
