Good morning,
I have pretty much every control measure dialled in.

I have noticed my buds being quite airier than I have run in previous locations and setups.

I currently run 6” exhaust on a day night temp setting.
I can’t (security reasons) and don’t have a direct inflow of fresh air from outdoors. That being said, my garage is quiet drafty so I assumed I would be okay on the fresh air front utilizing my exhaust to draw in new air into my tent.

i noticed my buds being fluffy on my last run, but chalked it up to lighting.
this because I only had one 315 cmh for a 4x4 space.
Previous run I added a 315 and noticed a increase in production but not so much to the end density of the product.

IMO this leaves only low co2 levels.
What do you guys think?

I was thinking of adding a co2 enrichment setup but I’m concerned that a vast majority will be lost out of my exhaust?

never ran Co2 appreciate any and all advice in advance.

B
