Do you agree the 24hr light makes the tight nodes? Do close nodes = more yeild?

Its been my experience that under 24 hrs light (CFL REALY CLOSE) the nodes are super close, but I put some 3week old seedlings in for pre sexing an they double their size in a week?
The fem seeds are the same age an no stretching just unbielievably close leafs (you cant even see the stem lol).
The regs looked just like the fems tell the 12\12 started so i assume its the dark.
Ive heard that the tight nodes will quadruple the yield but takes longer an requires lots of side lighting.

Anyone else herd that about tight node spacing?
Is it the light cycle keeping em so close?

My plants r 1" away though 1/4" plate on Hps and mh mix, and never seen tighter nodes there growing on 1 another almost.... Not sure if it's good? But it is what it is... My plants r 7 inches high from dirt with 6th set of nodes coming in... Hope this helps!... Oh nodes r double aswell two stems both sides at all node points

Lol if you still don't No?
