Shit man goodluck w/ your home. Just be careful as being in jail is worse than selling your home. More plants do not equate to more bud..just more legal issues, trouble taking care of, and a shorter veg time...If you are vegging in another cabinet you will have time to veg your girls as you flower cycle will run 60 days. Even SOG in this space you wont be able to do more than 10 at most.
More plants does not necessaily equate to more bud. I have seen people on here and other forums pull a lb or close to it out of cabinets 3x1.5. Search some supercloset or coolcab grows. These grows i have seen use 4-5 plants. I feel i can do it w/ 3 if i veg for 2 months and get the SCROG dialed in. The light mover will serve no pupose if you get 2 lights. I would get 1 light each side and no light mover. I would even think about going 2 400's. They would be easier to cool and the difference in bud wont be much if any. I use a 478 cfm fan to cool my 600w cooltube alone. I dial it to around 300-320 with a speed controller.
If i were you...and wanted to go 2 lb total.
1. Two 400s, no light mover
2. Highly reflective rubber paint
3. 478 CFM S&P 200x inline fan for the light tube that houses both lights
4. Spend the money you save from not getting the light mover on C02 controller. C02 will increase your yield, and more importantly allow you to run temps around 90. Cooling the light tube alone will allow you to keep your temps at 90. This will mean you will only exhause when your humidity gets above 50% for flower. This will increase stealth and reduce smell.
5. TD-200x or TD -150 and a can 33 carbon filter. You will want to get a speed controller because you will want 200cfm max going through the filter.
6. 4-5 Plants each side.
7. High producing strain like skunk or donkey dick or ppp that grows large thick colas.
8. Use SCROG instead of SOG because you have a small spave and more control. (Most people you see doing SOG would be doing scrog if they could put up a screen in their growroom.)
9. Grow medium...i prefer dwc for ease and fast grwoth. Do whatever, stay away from aero in my opinion unless you have at least some experience with the strain.
10. four small 4" inch fans that are 6$ at wallmart blowing up through the plants to push the c02 up
11. Two 6" or 4" fans to blow the top of the plants.
12. 3" or larger netposts
13. Consider a water chiller for the DWC, it will keep the plants healthy and increase growth.
14. At least 6 gallon dwc per plant. So 5 plants 30 gallon dwc. Larger the DWC res, the less maintence for filling, less ph-tds-temp fluctuations.
Now if you will be vegging in another are try to veg them in a dwc bucket you can just transfer...it will be a pain if not impossible to untangle the root system.or...use dividers in the DWC res or uses individual dwc buckets.
edit: i think you mean light hangers not light movers..they are different things. I use light hangers that allow you to adjust height, they dont move horizonally.
