beginner sea of green help

Hey all, i live in cali and i am going to grow indoors for the first time very soon here. i have a nice outdoor crop right now, but during the dry spells i need a lil sumpin. anyways, i am looking at a sea of green with one plant per square foot, a 3x4 foot area about 6 feet high. heres a few Q's.
1- I want as much light as possible, $ is not a prob, but space is, is 400 watt HPS too much(many?) lumens per square foot? figure about 50,000 lumens output over 12 square feet, that is bout 4,166 lumens per sq ft.
2- in a sea of green, is it advised to top them, or let them grow just one top?
3- I read about leeching rockwool cubes because of Ph, is this necissary when rooting clones?

any help is much appreciated, this is a picture of a premature cola of mine right now, it is an early harvest breed of indica that i am too stoned to remember right now, harvest in 3 weeks!! ;)

you'll use a 400WT more effectively in a 3x3 area(44WTs psf)in a space this size you can raise 16 cuttings in 6" pots,in a sog you dont have to trim them,you want to harvest single stalk colas,you can induce the photoperiod at about 6",use a good reflective material(foylon,reflectix)to maximize the lighting,rockwool must be pH stable before it's used,this is done by presoaking it in a solution of phosphoric acid(pH 4.5)for 24HRs....bonbon

Here is a pic of that same cola bud today, quite a change from just a month or so ago. and a pic of me hiding as well, hidin' in the bush! just a few other crop pics. all for medicinal use of course. Tell me what you think! I am not sure what strain they are, but the early bloomers are ICKY STICKY and smell a bit like bubblegum.

your outdoor crop does look like ya know what you're doing but i suggest either a stronger hid or using the one ya got in a smaller space. i don't think you'll be happy with 40-some W/sq ft on your present grow space. cut the space in half...if i were you. i use a 460, sun-agro for 5 plants (topped once at 3rd-4th node, in a 4-5 month total grow from seed) and end up with a minimum of 1.5z/plant in a modified sog, stadium style.

great job with your current grow!

yeah, well done with that grow. hope it smokes aswell as it looks.
im sure you will make the move indoors with similar results. you seem to know what youre doin..just keep doin it.

I have decided to go with my bathtub, which is 2X4 of "useable space". that should give me 50 watts per sq foot. thanks for the compliments, i ate a bud fresh off of the branch that day and it was super spicy.
