NEW room help/

hey guys whats up. i been reading and reading. after my last grow there was some thing i really wanted. co2 , scrog netting set up. and go back to hydro.
so i geuss my first question is wit a 1000w hps " im still looking for hoods but i think im just gunna buck up and by 2 mew xxxl magnums and run the air system threw this. what can i exspect the foot print on these to be??? i was thinking of running it like say 2 in a row. so like a 4 x 8 rectangel/ or what ever the actual light spread would be. also i have a light mover but i really dont want to realy use this to exstend my foot print. only to be used for getting the shadows and give the plant more light coverage down lower. so with that being said what can i exspect for a good light print??? im only going to be having my 15 plants. and i really want to get the best out of the 15 i will have. thats why i was thinking as big of a scrog patern as i could cover. so i could bonzi and bend these into so big busshes.
my next question is cooling with co2. so i have never grown in a room this size before. its always been a little closet for me. heat was always a isue. so this room is about 16 by 12. i was wanting to inclose the actual grow area with panda film so i could make it some what air tight to keep my co2 in. i was thinking of runing a 6 inch fan threw the lights with ducting. which should be some what air tight right??? so i wouldnt be lossing lots of co2?? this should keep the air cooler by removing the main heat source right??? and then i was going to mount some of those wall fans in the room to move the co2 threw the plants.
any tips? where am i going wrong.

OK, well heres thing with c02.
You need to bring the temp of your room up to the 90's and at the same time keep your rez water temps close to 70 degrees for c02 to be effective. and this only takes a week off the grow time.

The other big thing is this room in a living area with humans or animals ?
C02 can flood a whole house because it is heavier than air and kill.

The foot print of a 1000 watter is 8 x 8 but I stick with a 6 x 6. with light movers I'd use the whole room. That could be one hella screen of green.

o yah . the room is off sight. it goes house, garage,then a seperat garage. so there all conected. but the last garage. was built ontop of gravel. althow its atached to the main garage the rood is intirely seperatet. si 6x12 should be great for 15. i should be able to do some monster bushes. my ether question is how do you get into the middel to take care of triming and what not??? i was thing of building a 4x4 bridge that i could like move over the plants and just move it climb up like a later and walk out it like a platform similur to a scafeling. with the light mover i really dont want it to be going the distance as i read event 5 minutes without light can stop production. im not sure if thats true. but i really just want to use it to go maybe a foot each way to get all the angels... so with the co2 runing i really dont want to be pulling in fresh air right??? so if im running the 2 xxxl mags then i would run like inline fan to soft duck to first light then out the light into the next out that light into attic with scrubber atached??? the xxxl mags have lens on them right??? so this should remove some heat without effecting the co2 levels to much right?? also i bought a great ac unit. but i dont think im going to have to use it just with the size and only running 2 lamps. if i did have to run it how do people normaly run them without wasting all your co2??? because as i understand it. you only want the front of the ac unit within the room and the back needs to be boxed off and vented into the attic.??? reson i was thinking ac was because in the past my closet got soooooooooooo hot my buds got stretechy and looked more like ditch weed. but from what i read you need to get these warmed up. so then my idea to cool the water would be run it threw a house out side the house maybe installing a radiator with a electric fan. but i feel as if im being to over board. like i see all your guys set ups and they look better than i could ever dream of. but being a plumber im always looking to make stuff to complicated.

Next set of questions. in my last ongoings with hydro. i did the ruber maid with the holes in the top and had a top dripper on the. it worked all right. however i felt like the plants were to close together to really bud out. i like short wide plants. bonzi if you will. so what is the easyest to start up and use for the scrog style. i was thinking the buckets and conect all together for return back to the holding tank and use one pump to feed them over the top style.

o and the ether thing is i bought some of those 360 misters. so what i was actuly thinking is in the botum of the buckets runing some tube like 3/8ths into the bucket and inside the bucket putting like 5 of these misters on the tube. so it should be major mister..
