With regards the question of stable CO2. I think folk sometimes confuse unstable with unavailable. My understanding is that plants will adapt to their environment or ultimately die. For instance, plants used to a low-energy environment will adapt accordingly and compete to use up available CO2 at the beginning of the photoperiod. In this case the CO2 is not unstable it is just not available throughout the entire photoperiod.
I guess it's a good question to ask "What are the criteriums for unstable CO²?" I find the term unstable CO² rather confusing in it self. And in many threads at the end, it becomes even more confusing because there are so many individuals takes on it.
But it must be possible to narrow it down in a simple summary everybody can understand.
To give a short summary my best guess.
stable CO² =
1: A stable bubble count during the entire cycle.
2: A lime green drop checker at lights on.
3: Sufficient distribution/flow.
4: A good quality diffuser.
5: ? or more?
Then if one of these is not met, results in an unstable CO² distribution with all its consequences...
