First Time Grow attempting to Yield 2oz per plant

I will attempting my first grow soon and am planning on using:
-1 600wHID Aircooled
- 2 DWC/Bubbleponics 18g reserviors each with 5 clones.
-Rockwool,Hydroton
-General Hydroponic Nutes
-Mylar

I plan on utilizing LST/supercropping/topping to maximize my light penetration and am willing to veg for as long as it takes to reach my goal.
My Questions are:
- How tall should I let my girls grow in Veg to harvst 2oz per plant?
- Which strain is best situated for such a harvest? (i was thinking NL#5) or will any indica strong hybrid from a dispensary do? (I live in Ca and just got my prop 215 card)

(working with about 5.5 ft of total height space)

Thanks ahead for any info you guys may have to help.

I've gotten 2 oz from a 16 inch plant so not sure it's about height. Yield will be more about all the little factors but on how tall to veg, I'd say 24 inches and some of the indicas won't even get there.

THanks IL SMile, wish me luck!
