Mine is a drip system in a tray with square pots 10" high, and about 5"x5" at the top, filled with hydroton. I've gotten 2.5 oz of dry bud per plant (dry).
I flowered my recent batch of Purps (indica strain) at about 10-12 inches and they are now four weeks into flower at about 2 feet tall.

You get over two pounds per 1000 watt lamp? What size are your pots in gallons?

I ran Sour Diesel with the plants on the floor, and got over a pound a light... when they were on the floor I waited until 18 inches before flowering which took a little while longer than I like to veg for.

When I ran the same strain on the tables (2.5 foot high tables, 7.5 foot high ceilings) I flowered around 9-10 inches and got .6 pounds per light - A HUGE FUCKING DIFFERENCE.

I can't wrap my head around it because it seems basicly the longer you veg with that strain, the more herb you get..and other variables hardly change a thing. I had 3X better technology in my room the second time I grew it, as well as 3X the smarts when growing herb.

What I want for a low ceiling is a large producing indica... my room is a bit packed and it's just easier to deal with. Having a hard time getting my hands on an Indica that produces as much as the Diesel is supposed to. Have friends pulling two lb per light with SD, high high quality herb.. some of the best I've seen here in California.

I ran one less plant per 1000 watt the second time around, but they just didn't fill in well. Considered topping them, but that takes time with veg too.

In any case, I'm a bit frustrated that I can't hit the same numbers as I did the very first time I grew.
