Pretty much as the title reads. I know in standard photo growing you wait until flowering. But with auto flowering seeds when would i want to introduce the Co2?

Thanks for the help
 
i would when you start to see the pre flowers. they veg so fast, if at all, that you could even just run the entire grow after they are established.
