Figure also that a watering system will go below the plants. A flood system tray is about 2-2.5' tall to provide room beneath for a res tank.

You really don't want a plant much more than about 3' (1m) tall. That's about the depth limit for foliar penetration of a 1000HPS.

I can actually have 12 plants in veg and 12 in flower cuz I'm growing for my sis too and there's a provision for that in the law. So I'll have 12 plants and just need to decide what will be the most efficient to way to farm them.
damn, lucky you.

12 in flower still is too low a plant count to consider using SoG in the standard fashion. I put twice that many clones into flower in my SoG every 2 weeks. Plants grown in true SoG style only yield about 3/4-1oz per copy, but if you're harvesting 23 every 2 weeks as I do, you make up for the low per-plant yield a bit.

You'll certainly be vegging the plants you intend to flower to make them large enough to raise the per-plant yield to something decent. I suspect you'll either be tying down the mainstems or pruning the growing tips off mainstems themselves in early flowering (perhaps in wk 1-2) to make the plants bush out a bit.
