NO that is not what I am saying at all.

CO2 in regular temperatures will not make plants react in the same way as CO2 in ELEVATED temperatures.

For CO2 to be effective you also need to boost your temps beyond what would be considered healthy for a plant in a non-enriched atmosphere.

In REGULAR atmospheric conditions, with ELEVATED temperatures, a plant's metabolism will crank up but it will start to show signs of stress as it transpires gases and water fastern than the roots can take up water and the leaves can take in CO2.

In ENRICHED atmosphere, the metabolism increases (and yes this is what decreases length of flowering time) BUT now there is more CO2 available, and as long as you keep up with the plant's water demands so the damned thing doesn't croak, it can put on far more mass...

Anyway we are talking different languages. I never EVER in any of my posts said that you can 'just crank up temps and get the same results'. We're talking shortened time to harvest, not whether you can grow a much better plant using CO2.

I have no idea whatsoever how you interpreted my post in that way.
