I was concerned about that too when I started with my DIY CO2.
Unlike most houses in the US, we like to keep our day temperature
around 63-65F, and night around 58-60F. Other than taking 24 hours
to get started, and 48 hours to really get going, I have no complaints
about the CO2 production. It usually lasts for about 3 weeks and then
starts declining a bit.

I suspect most of the variations on the length of CO2 production
are due to the type of yeast, and to a lesser extent, the sugar.
