I know this old guy 😆 thats running the co2 bags in his non sealed room and his plants are like ....OMFG...

That's what I'm trying not to do. But it's either shell out for a ac or vent. And I need a humidifier so it looks like I'm venting. Is it still considered sealed if you're running an exhaust with no intake?

I want to be there when your grow room implodes. That's a hellacious exhaust fan.

The manufacturer of the Exhale bags states on their website that if you are exhausting out of the room, just place the bags on the floor at the opposite point of the exhaust fan and let it draw the co2 up thru the plants and out. It may not be ideal, but it still impacts plant growth enough to make a difference.

Lmao. Am I thinking wrong when people talk about a negative pressure grow?

Oh yeah.
There is an HVAC guy here, I forget who, sorry, (He builds hospital rooms). But the whole point is to have enough airflow so that you don't notice it, it just keeps everything moving out.

There is really no such thing as a sealed room grow unless you plan on providing oxygen and everything else...
If it's sealed, they will eventually die from lack of replenished air.

Have to disagree bro.... you only need co2. Fresh air is what exactly?

I run 0 air exchange other than going in and out of my room.

Plants make a lot more oxygen then they consume so you absolutely don't need to supplement o2 and only need to supplement co2 as they hold onto most of the carbon.

Unless you run a co2 burner... then it's needed to get rid of other gasses produced like ethylene from inefficient burners and carbon monoxide etc.

100 percent true. No one supplements with O2 in a sealed room.

Nitrogen (N2)78.08%
Oxygen (O2)20.95%
Argon (Ar)0.93%
Neon, Helium, Krypton0.0001%
Carbon dioxide (CO2)0.038%
Water vapor (H2O)0-4%
Methane (CH4)trace
Sulfur dioxide (SO2)trace
Ozone (O3)trace
Nitrogen oxides (NO, NO2, N20)trace

We still need some of these, but not all, and it's won't kill us like a deprevation of O2 would.

Like I said before, I've never run Co2 but it seems that a sealed room would eventually run out of something that is necessary for plant life.
 
#52
Nope... i know nitrogen is not taken up except by nitrogen fixing bacteria.

I have run a completely sealed room for yrs

Yes your right they will die without supplementing co2.

But not o2 if I remember right they produce about 10x the amount of o2 as they use.

O2 is never a question since plants are the Earths #1 supplier of it.
