Best way to supply plants with co2 is...?

Discussion in 'Indoor Marijuana Growing' started by KMilz, Sep 27, 2011.

  1. I recently acquired a co2 tank meant for soda lines in a restauant, and was wondering the best way in which to use it; I know a regulator would be a good start, but money isn't available at the moment so what I reall would like to know is:

    -where to put the source of the co2 in relation to the plants
    -how long to leave it on, and at what times
    -whether or not I need to turn off ventilation for it to be efficient

    Sorry, I'm sure there are already other threads that state this info, but a very brief perusal of threads didn't net me the info I was looking for, so any help would be appreciated. Thanks!
