Re: What is guaranteed to happen if I don't use Co2 in the grow tent? [Re: World Spirit]

Adding CO2 isn't required, as long as you have adequate ventilation.  Cannabis only needs so much CO2 to continue to respire.  Any extra goes unused, unless your grow tent is warmer than the optimal "without CO2" temperatures (mid-high seventies F or so).  Don't know the details off the top of my head, but the reaction(s) involving CO2 are what I want to call "heat dependent," though that's probably not the term.  Either way, more heat (up to a point) means more CO2 can be processed.  Less heat means less can be processed.

This is nice for some growers for a few reasons.  First, more CO2=faster growth, and (some claim) bigger buds (I've seen evidence for and against this hypothesis).  Second, due to the heat thing discussed above, growers with heat issues can sometimes resolve them by adding CO2.

To add CO2, your ventilation needs to be well-controlled and -contained: you don't want all your $CO2$ leaking out all the cracks, and you don't want your fan sucking all the CO2 through before it gets to be absorbed.  So there's a "linger factor," some sort of balance that you'll have to research more to find out about, because I don't know shit more.
