Co2 and positive pressure

I’m in the transitioning phase going from vented to sealed room, now I have sealed most of the room already and I have the air con in place, the only thing is that the air con is single hose.. so because of that I’ve had to build it into the wall so that the intake is outside of the room and the cold air outlet is in the room, this is so the co2 doesn’t get sucked up and exhausted. I know I’m going to have a positive pressure issue because of this, I’m wary of the positive pressure pushing the co2 out any gaps and end up burning through loads of co2. Had anyone had a similar problem or can give some advice? I figured I have 2 options... 1 is to just get on with it and see what happens with the do2 consumption, 2 is to have my exhaust fan on low speed in there.. I have a speed controller so I can have it on low and I was just thinking that the oxygen is going to be at the top of the tent where the exhaust fan is so maybe it will suck out mainly oxygen rather than co2? Dual hose or window air con are scarce here in the uk it’s so annoying, so it was a choice between a split ac or a portable single hose... in hindsight I would have probably juts not done the sealed room idea but i didn’t think about the positive pressure issue before I ordered all the equipment lol any help would be great

ok I understand that , sorry man your options are limited to that I don’t know any other way to cool your room other than water cool everything and exhaust your lights with vented hoods and maybe that way u might not need the A/C but then it’s getting pricey .... good luck bro happy growing

humidity here is too high for water cooling lol I’m using LEDs I have the drivers out the area which helps.

Wow it's so crazy how fortunate we are for freedom of being able to literally buy anything I want at anytime of the day , Canada kinda like the UK too I go there often and you can't find shit there !
