Will creating co2 elimitate need of intake/exhaust?

If I did one of the co2 generator things (ie. water/sugar/yeast) would I still need to have intake/exhaust out of my closet?

Im trying to do whatever I can to avoid cutting holes thru my ceiling and wall.

Thanks in advance. Will surely +rep!

No you would still need a exaust fan and a fan in the room to harden the plants also creating air movement.If you did not or could not get an exaust fan then you will need a ossalateing fan 100%.A good way of getting air out of the growroom is to cut a hole in a crawl space or loft space and get a small fan that is aimed at the hole this will force air out of the room.I would put more than one in the area you are gonna make the hole this will help with keeping temp down and bring in fresh air.Run some dryer hose in and just point a fan at it this will remove a little of the stagnent air.

Ive already got 2 fans in the tent (which is in the closet) to help circulate air. Was hoping if I could keep temps under control, that I wouldnt need to intake/exhaust out of the closet if creating co2.

Would I still need to do both? OR could I just exhaust thru the ceiling and intake air from outside of tent but inside closet?

also interested in this conept

you would still need everything. if all your thinking about is taking shortcuts your bud will be short too
