Air Circulation. 2 room set-up + CO2

My setup is that one room is for mom/veg, and other larger room is for flower.

In veg room I have a filtered intake with an intake fan attached, but no exhaust, so I am straining my fan.

In flower room, same deal, but no filter, as i can't afford one.

Both rooms have co2, with separate sensors and tanks in each room.

My plan is to turn the fan in the flower room around, connect it to a carbon scrubber that i already own, cut a hole inbetween the flower and veg rooms, and move the veg room intake fan to blow between the veg and flower rooms, leaving the filter on the hole as a passive intake. Thisk would bring filtered air into the mom/veg room, flood it with co2, then drain it into the flower room, where it is reenergized with co2, and finally exhausted out through a scrubber.

Does this sound like an ideal situation? Should I stay airtight? My equipment for airflow are the 2 inline fans, the carbon scrubber, and the hepa filter. Any suggestions would be welccome.

Co2 in ur flower room only, dont waste it on moms and clones.. seal ur flower room up completly.. as for clone/mother room, wel i was in the same pos myself, unsure whether to have them share same re-circ air or what.. but i decided to keep them seperate and exhaust mom room with passive intake through the floor,,
This was bcos i came to the conclusion that it was more efficient to control the flower room environment the smaller i kept it, if it joined to the mom room then thats a larger environment id need to control,.. it works out less ac is needed, less fucking around to keep ducting between rooms lightproof, less co2, less heat and instability created from the mom room and u can control ur flower room much more tightly which is important if u wannna produce..
Also its not such a big deal to control mom room environment so closely cos they just moms and theyll be alright so its less stress i think
And just attach a fan to ur scrubber in flower room and let it re-circ the air, it dont need to vent out..
Dude ur plan seems pretty easy with both rooms sharing air which is what i really wanted to do but in reality it was a hard thing to achieve properly, and like i said i think theres more benefits in controlling the flower room seperatley

EDIT: i should say that my rooms are in the 1 room thats seperated, i think ur talking bout 2 seperate rooms so im not sure if anything i said is relevant dude, sry

as long as you keep the contamination to a min sounds good to me . course im high as hell and it sounds way complicated lol

you can get a controller that will not allow the fan to operate while the CO2 is being released. So that way you could save money by not having to control the air of each room seperately. But you want different humidity levels for each your flower room and veg room so I would have to agree with street legal and start by controlling the environment in the flower room and when you get some extra cash from your harvests then work on controlling the environment in your veg room and keeping both rooms seperate and sealed. The problem you will encounter with sealed rooms is heat, so you may need an ac unit (preferably a mini split a/c unit because it does not exchange air) and use an intake and exhaust for your lights so that when your lights are being cooled it does not pull air out of your room. I would also suggest getting a good book off amazon, they work good as a quick reference nad you can get one for 15 bucks new.
