Any reason to ever vent room with CO2 and AC ?

[poindexterous]

Just wondering if there's any reason to ever vent a room where a CO2 gen keeps 1500ppm, and an AC keeps temp and humidity at ideal levels???

I'm sure the room breathes a bit and oxygen is never depleted as I never pass out and the CO2 gen always fires up, also CO2 ppm drops from 1500 to 500 during 12 hours of dark. Just wondering if there's any reason I'm not thinking of to run vent fans now and then?

No reason at all. That's why we seal them. 1500 ppm co2 isn't a problem for us to breath.

i was just gonna say...that's why they call it a SEALED room, lol nothing in, nothing out...

Very good, thanks for confirmation, just makin sure I wasn't overlooking anything

It does seem counter intuitive at first. Watch your humidity very close.

no.

A small exhaust fan connected to a charcoal filter creates negative pressure in the growing area. I have this connected to a fan speed controller. This ensures there will never be odors leaking to the outside world.

If your using bottled co2, your going to have a hugh co2 bill. You could go through a tank a day doing this. Sealed means sealed, contain the odor and use an internal scrubber. You don't want + or - pressure in a sealed room.

where im at o2 cost's $120 a grow(for me 8 week grow).compared to what im gett'n back ....that is a fraction....i use bottle o2,where you at budleydoright?...how far in the BUSH?

I was going through 3 tanks per cycle, I have recently resealed everything and think I have it down to 2. At $20 bucks for 20# .

Before I resealed, if I turned off the co2 the plants would draw it down to 100-150, never lower. Now they can draw the Co2 down to 0 on my digigro meter. I have only gone through one complete tank, am on my second and only have 2 weeks left. i may have cut my use in half.

So internal scrubber..that means just a small fan attached to a carbon filter,but NO ducting correct?..wont this still create negative pressure..Im running a halfassed sealed room,using this method.

Also,Im worried about the SMELL,whenever I open the room to water/care for the plants.

Will the internal carbin filter cover this?

Lastly,would a portable a.c be enough to cool two 600's?
