Sea Of Green

OK. I've made a switch to Sea of Green style. I've grown in 5 gal pots for awhile but my grow space has become alitte smaller so I think I can pull more yeild this was. Any advice? I'm going to do 2 4x4 trays. under 2 1000HPS. vegging for 2 weeks then doing the 12/12 flip. Using GH 3 part right now but doing the switch back to Canna on the next run. Watering once a nite for 15 mins or top feed. Let me know any advice or something that would increase the yeild on this. The goal is 15 grams per plant. I'm also thinking of doing a different strain for each 4x4 tray. Blackberry Kush, Agent Orange on the first run.

Any advice on this? What has the yeild been for people that have done sea of green this style? I'm from the thinking of less is more so doing it this way is alittle out of my comfort zone but I have heard and saw great harvest on this kind of set up.
