Co2 levels and air exchange Thanks!

Ok so basically im going to be doing either a 8x8 or 10x10 grow room within a room soon i havent decided on which yet, reasons for doing a room within a room is so i can have more control over air theres many leakes in this room already with huge ceilings. Which to me sounds like uncontrollable air for the most part and escaped lighting. i havent decided between 2 600 watts 1 1000 watt or 2 1000 watts, basically i want to grow 2maybe 4 plants from seed low stress trained or supercropped topped a little, Scroged and bushed for big yield. Im going to top early at the second node so that once plants are strong in veg i can grab those 2 stems at the first node that are now huge and turn them into mothers basically i want some comment on that idea by the way its gonna be from super soil i've had 'cooking' or inoculating for the past 40 days. once i get those mothers and get a nice amount of clones ill prolly set up a big time Sog either with rockwool cubes close together in trays with drip irrigation or something of that sort possibly a couple dwc systems with like 6 plants per tub but then again i dont know how close roots can be when it comes to touching each other in water, Anyways enough of the rambling basically wanna know if an intake from the outside room into the 10x10 room i create and then a carbon filter with a outake fanbon the other side sucking air from inside the 10x10 to outside the room and finally outside the window or another room? then what about my air cooled lights a whole different ducting setup? let me know im down for a huge discussion

Ok so i got it, im going to either push or pull air from one of the other rooms in the house where co2 gets refreshed by almost constant ac is it ok to pull that air from the top of that other room, it might be a little warmer but co2 should be great. another thing how far can ducting go before another fan has to be placed on for efficiency and perfect airflow we dont want any hot spots. it will be pulled from the co2 refreshed room into the next bedroom through ducting but only escaping into the 10x10 grow room that i have talked about. That should handle all Co2 enrichment properties for proper bud structure and growth. After that is done then we will move on to lighting and ducting for that Thanks ill be happy to post pictures once this is all on its way. i look forward to feedback i appreciate it and so does everyone else on this sight
