If I may add.....

1st off, your watt output, in your flower room, is 646 watts; not 2150 watts. 2150 watts is totally irrelevant here. We're looking at the watts your bulbs are pulling. Your 150w "replacement bulbs" are using only 40 watts, 100w's are using 23w. SO, your using 646 watts to power you flower room. Not sure how you came with 480w? You lights are producing 36,700 lumens of light.(keep in mind lumens will diminish over bulb-life) Now, that's a very good lumen/sq. ft. ratio, pretty good overall. But, just know that 600w HPS HIGH OUTPUT bulb emits 95,000 lumens. So when you break it down a 600W HPS H.O. is bringing 158 lumens/watt to the table; your current set-up is only producing 57 lm/w.(rounded up) Ultimately, your producing 3x LESS the amount of lm/w with with 15 bulbs as opposed to 1 bulb while burning 46 more watts. Lumens are the amount of visible light emitted from a source. More lumens = more visible light = deeper penetration into your canopy.
A 600w, cooltube, HPS light will run ya about $200, with everything, digital ballast(uses actually less power), reflector, bulb, and cords and necessary fixtures, you 4-6 inch fan to cool it....$30 bucks. You would be able to have you plants closer with a cool-tube than CFL's and your temps would be a hell of lot cooler. FYI also, no one uses Halogens to grow, a 5 year old maybe.....maybe. HPS, MH, these are called H.I.D. lights (High Intensity Discharge) that's what they are made for, lighting up yards and buildings and shit. Closest thing to natural sunlight.

2ndly. Pretty much all the strains you list have an 8-12 week flower period. the Hazes will be on the longer side considering they are sativa dominant. Your looking at 2 weeks in the seedling stage alone.(A seedling does not shed it's cotyledons for about 2 weeks) So, there's 2 weeks in the seedling stage, then add another 2-4 weeks for vegetation, 2 weeks would be the bare minimum IMO. Plus your 8-12 weeks of flowering(every strain will finish at different times) I have heard of some heavy indicas that can finish in just over 6 weeks, i believe Blackberry is around 45-49 days, pure Blackberry. Your basically looking at 4 months from seed popping to trichs turning amber more or less.
Ruderalis is being used now crossed with some strains to shorten the flowering period. But basically its the stuff that grows wild in ditches and pastures. It's also the shit they were smoking in Reefer Madness back in the 30's. It's an auto-flowering strain, so it doesn't need a change in the light cycle to start flowering necessarily.

I'm just seeing too many discrepancies here. This may seem well thought out, but in reality its excessive overkill. Inefficient use of space and lighting and time. If you did plan to LST, it would actually make the process longer, FIM-ing too. Think of FIM-ing as....your basically cutting a person's foot off and telling them to run faster, as soon as you cut the top off of that plant it is going to go WTF happened??? It's going to slow down for a minute and try to figure out what to do now. It'll take back off in a week or 2, but the added stress will slow it down which you don't seem to have to time for. Patience is virtue.

MG is usable. In a case where it is the only thing available I can agree. But, it takes practice with MG to use it how it needs to be used for growing marijuana. I'm don't have time to get into it now.

Overall, good concept. Probably could have spent your money a little more wisely. I suggest reading up more before you jump into this. Know the tendencies of your strains. Focus on 2-3 strains first, pick your 2 favorites and try to make each cycle more productive than the last one. Pick one that clones easy, roots faster, flowers shorter and in less time. 5 AK-47 seeds are going to give you 5 different plants; the characteristics of each varying. 1 will ultimately best to pick of the litter, 1 will ultimately be the runt of the litter, the other 3 will suffice, but we don't want average here. We want the best of the best, the Top Dog.

I'd ditch your sandbox idea as well. Your plants will need to be about a foot apart to have adequate room for roots. I've read the 3lbs. per light growlog, a few times over the years, pretty awesome i know. On a big scale it'll work, small scale....no way. You may get to week 5 of flower and your plants may start to kill each other off with one plant basically winning this royal rumble. A good rule of thumb to remember is that these plants need about 1 gallon of pot space per foot of plant. So a 3 foot plant should be in a 3 gallon pot(before it reaches 3 feet). It should finish at 3 feet.

Im not trying to rag on ya or "hate" on you. You obviously have the drive to produce some top shelf buds. It seems to me you have been misinformed on some major details. Or you may just think that it might work. Stick to the basics and when you get that down you can start experimenting.

Can you fill me in on your germination methods btw? Just curious.

Peace.
