CO2 recommendations

So, I'm in need of some CO2 addition with how much light I have. Looking to get a controller with bottle/diffuser set up for around $600 if possible. It was just a number thrown out, not set in stone though. I have never looked at CO2 as I never thought I would be at that point, hell I didn't even grow this time last year. If for just a little more I could integrate some temperature control in as well that would be great.

In a couple years i'm sure I will just get some PLC parts and make my own controller. It would be extremely easy since I do that kind of thing at work, just not real cost or time effective at the moment.

Are you running a sealed room now? CO2 is a waste of money otherwise
Not exactly. At the moment, this is what my airflow looks like, not the best drawing but i just threw it together for this purpose sorry. With CO2 added, would not have the A/C intake sucking from tent. Aware that a lot of CO2 will still be wasted. Also not set in stone on CO2, just not sure where to go from here and with the amount of light I have it makes sense. Some might suggest hydro....NOPE sticking with soil

I know CO2 usually needs a sealed room. Nobody has had any success with circular air flow through tents and using CO2?

Good read on Co2....


Co2 supplemented or not.
Most important I learned about the need to vent. When and why. My biggest mistake was not venting properly during lights out.

Air conditioners do not bring fresh air into the grow. Mini-splits included. They cool and recirculate the air in the room. (Yes. some ac's do have fresh air capabilities. Few.)
