Thanks . I think fresh air is required in dark cycle

Room size matters. One can use tools like this for cfm calcs.
If you room is completely sealed you would probably need fresh air. Most rooms aren’t truly sealed. My room will return to ambient CO2 levels (300-400 PPM) during the night cycle when the controller is off.
The article @GramTorino linked talks about venting the room right before lights out. Did you read that link?

Fascinating subject.
Always wanted to run co2 but the complexity has me intimidated. Exhale bags for me although I’m not sure if it even works.

Awesome knowledge being dropped here, thats why I love this site. @GramTorino great article man thanks for linking it! Also thanks to @ReikoX and everyone else for sharing your knowledge on the subject. I am planning on building out some sealed rooms here in the next 6 months so I have been thinking about this very topic so I appreciate the conversation.

Are you seeing a noticeable difference yet? Did you run co2 during your veg as well?
Yes, its definitely paid for itself in terms of yield. In veg I only ran it at 600 ppm. Here they are at day 40.

Excellent work my friend!
Are you in hydro?

No, living soil beds bro. Yield is up due to CO2, quality is down due to other issues though.
Jesus buddy, your in a stoner forum, topics move wildly.
Your answer is Zero…
What was the point of this thread if you knew the answer you were going to do already…
