600w MH/HPS SOG + P.P.P strain... expected yield?

[The Grim Reefer]

Hey guys and gals. I have a 600w Lumatek/Hydrofarm setup (cost me $400 for just the ballast and reflector...yikes) and plan on doing a SOG grow with some P.P.P. which is supposedly a good yielding lady. If done correctly about how many ladies could I fit in this spot and about what would I realistically expect to get when all is said and done?

8 rows of 8 plants in a 4'x4' = 600 grams

600 grams divided by 64 plants = 9.375 grams per plant
