I think this should have been mentioned awhile ago: the main grow is a 1-time only thing. I have 6 months to grow these plants and will allow as much time as necessary to cure the buds. After that, I'm done with it and just having a (much nicer) perpetural SoG going which should keep me high for cheap for the rest of my life.
OK, I haven't mentioned ventilation. Not because I haven't thought about it, but because I have thought about it and basically have the entire thing planned out. All of the ventilation will be ran through dryer ducts above the shed. Please look at the attached picture.
I'm putting a DIY Cooltube on the 400w HPS to keep it cool and am building a DIY carbon filter to freshen-up the air before I send it outside.
Above the mother room, there will be a ~1' space where I'll have all of the outtake.
There will obviously be more ventilation in the main-grow room, but I'm too lazy to make a 3D model of it (I'm using MS Paint).
More lighting is not an option. And please don't be shy - I'm not afraid of constructive critisitsm. It seems like everyone thinks that I'm way ahead of my self, but IMO, I'm not. If I am, please let me know, but explain to me why my ideas won't work (telling me "you need more light" over and over again doesn't help).

According to this chart, a 100w HPS can cover a 2' x 2' area. I'm using a 150w HPS to cover the same area...The Hemp Goddess said:

In the picture, the red boxes are fans; the black arrows are airflow.

OK let me explain how to figure out if a light will cover a certain area.....
To have proper lighting you need 3,000-5,000 lumen's Per Square Foot, 3,000L being the up most minimum of light you should have and 5,000L being average. So if you have a 2 foot by 2 foot SOG room, thats 2x2=4 square feet. Now you take that 4 and multiply by 3K & 5K and get 12K-20K is suggested. A 150W HPS produces just around 13,000 lumen's. So you just barley meet the min requirements. I would kick it up to 250 if you plan on leaving the SOG room up and want satisfactory results. And also if you are only using 4" pots they are going to get so root bound its crazy, and they will be like a jungle....

Everyone here is telling you things we think you need to know. You are expecting certain results that you are not going to get unless you change some things. Whether you want to hear it or not, the amount of light you have directly affects how much product you can get. And as Timmy has mentioned, you are at the very low end on lumens/sq ft. Also, a 150w has very little penetrating ability.
I also agree with Timmy on the 4" pots---you will be completely root bound in no time and will have to water a lot (something that is also going to problematic). If you have some kind of hydro system made with PVC pipe, you can get away with 4" pots, but not with a soil grow, IMO. We have already discussed the difficulty of moving the plants up a step every 3 weeks.
Unfortunately, ventilation is not as simple as it seems like it should be. You will not be able to connect all the fans to 1 run of 4" dryer ducting. You need to be able to draw fresh air in from somewhere. The air that is being pulled through the cool tube actually needs to be cool. Pulling hot air from around the tube will do little to cool it. In the summer, you will almost certainly have to cool your space and in the winter heat it. The noise from 6 fans will be considerable, and you indicate that you plan on more in the main grow room...

You should definitely upgrade your lighting. What you have now will not produce the results that you are expecting. I looked at that chart for lighting that you posted and it's wrong for mj. I have a 400 watt hps that I'm using now and I keep it 12 inches away from the tops. On your chart, it says to hang it 48 inches away! That's a terrible chart. Just my thoughts. Take care and be safe.

Thanks for staying with me through this, I have come to accept that maybe I really need to switch my state of thinking into how I can simply become more efficient, since I cant actually be upping my wattage by much more. So I have come to the conclusion that switching to LED might be the most suitable line to follow under. Of course this is gonna require a couple days of research since my knowledge on LEDs and growing is fairly limited. I would appreciate any good links to information on LED grows or even if an LED / SoG could be implemented, thanks again.

I hate to sound snotty, but I am an old arthritic grandma, so listen up.
If anyone here thought that LEDs were the way to go, SOMEONE would have mentioned it. You are not paying attention! Go back and reread everything that has been written.
Here is what I would do if I had your setup:
Forget the 1 time grow and concentrate on you permanent cabinets
Build a 3x3 space to SOG
Do DWC
Use a 400w HPS w/a cooltube.
Ventilate, heat, and cool as needed.
Build a 3x3 space for mom, seedling, clone and vegging
Use an aero cloner (except I like moms in dirt)
Use 2' T5 fluoros
Ventilate, heat, and cool as needed
This keeps you below your 700w max, maximizes what you have to work with, and will work for a perpetual harvest.
