I personally now do 4 plants, when I get clones they get between 2-3weeks veg topped, 4 branches selected to keep. Cut everything else off and LST those 4 to keep them equal.
I get 4oz near enough per plant and sees me through harvest to harvest without staggering any plants.
Well in all honesty it gets me EASILY harvest to harvest with PLENTY spare.
I smoke about an oz a month.
I personally like 4 plants in my setup.
Yours you could do 6 similarly to my 4.
Should rock you up around 600g for around a 13 week turn around.
