Co2

I was just wondering if co2 actually helps alot in the veg stage, or if its just mainly used for the flowering cycle..

its used in both stages. it mainly helps cut time off your grow, and helps promote nice large bud sites.

Yeah i heard it helps quite abit in flowering thats what i done last time but, i was wondering if it made it grow much faster.

I've used it through my entire grow, and am happy with the results so far. Check out my grow log in the proper forum.
Peace
