Ok so back to the original question sheesh!!
1g per watt is pretty much a rhetorical type question. I had 2 girls under 400w. Just harvested my AK47 and got almost 400g's so yeah 1g per watt but my next girl gets chopped here soon and by looking at her, she should produce close to 300g. Now thats 700g's "wet" from 2 plants....do the math and its about 300g dry. What if I had 4 plants in there? (max for that space and wattage). 1400g wet, 560 dry give or take?
You can go to my journal in my sig and look for yourself. Nothing crazy like fdd's monsters...bows to the master lol,,,,,but still a good quality indoor grow.
FDD please dont make fun of my tiny 1.6g deer turd dooky ball. It was my first time making hash and I prolly screwed it up somewhere along the line.
I guess the answer is that: If you do everything really good and have a successful grow 1g per watt is the goal. I'm talking indoor cab/closet HID type grow. Alot of the ppl on these forums are younger novelty growers that use a bazillion cfl's and flouros etc...even though some of the more experienced try to mentor and educate the younger minds, they "do what they want to do". And thats ok
but they cannot expect to get 1g per watt even though some do attain it.
