If you can't get at least 80 grams per plant it's hardly worth the effort.

Yes it's doable but it ultimately depends upon how many plants you plan to put under the 600.
4-6 plants yes it's doable.
Any more plants and it's doubtful.

If your budding 12/12 straight from well rooted clones with zero veg time you can fit 15 to 20 plants under a single 600 watt hps , amount of plants will vary with reflector size & veg time .
How long you veg the plants will ultimately play the largest role as to how many plants you can put under a single reflector .
I pull between 60 grams to 90 grams per plant every grow using a sea of green single cola style .
How long are you vegging them for ?

Depends on the size of the plant, container size, how much light per sq ft. I got 185g from a plant in a 2x2x5' tall space. That was with 162w of t5ho and two CFLs as sidelighting (probably 40w combined, I don't remember.). 200w total? That's 50w/sq ft.
I got 90g from an 85w ufo in the same space. That's only 21w/sq ft. Better g/w, but poorer g/sq ft.
Added four Cree 9.5w LED lightbulbs for sidelighting (123w total, 31w/sq ft) and got 150g.
This was the same strain in all three cases. I don't get as much from kush and afghan. They take longer to finish and I don't get as much. Just did Hindu Kush similar to 12/12 from seed (2-3 weeks of veg) in a small #1 container. It was a small 1.5' (maybe a little more) tall plant. Could have fit 4 in a 2x2 space. Got 22g.

Go for it ....definitely doeable....4 plants under a 600 with the topping method used and 4weeks of veg in 3 gallon containers should give you 4zips per plant....

The Last indica I scrogged in a 2'x2' space yielded me 230g finished under DIY LED's. You have pretty good chances!
How many watts did you use in flower?

I used 4 cree cobs driven at 60w each. And I also used 2 100w Chinese red LEDs prob more like 30-50 than a hundred, could be wrong though, I'm gunna have to test em now.
Thanks. That makes sense. You got 58g/sq ft, which is great. You used 85w/sq ft which is well past the point of diminishing returns even for inefficient (cheap) LED. You got 0.7g/w, which isn't bad. I thought it would come out to 0.5 (considering how far past the point of diminishing returns you were).
Just wanted to make sure the OP understands the tradeoff between watts/space/grams. (Wouldn't want him doing 30-40w/sq ft and thinking he's failing at 30g/sq ft.).

I do a lot of cabinet grows. And I had that fixture laying around, which is why I used it. Correct, in truth I was about 35w per sq ft over. I however think I did a little better than that formula suggests, reason being is my 6 LEDs weren't centralized I can move them horizontally and as much as the plant lets me vertically up or down. I also don't incur a lot of droop because my amperage isn't cranked up either. 30g per square foot with LEDs on a first time grow still isn't bad, especially if uses a cheap Chinese panel or two.

It's normal and what you should aim for if you grow 5-6 plants in there. It's going to be very hard with 8 or more.
