Unless you are ready to redo your room to make it air tight, I would not bother, if you got good ventilation. By air tight that means wrapped in plastic or something comparable that will not let air leak in or out, mechanical vents that can be opened and closed automatically depending on when your fans come on. The regulators and tanks or burners also cost good money. Just a bunch of hassle if you already have good ventilation. But a lot of growers like to use it and have the extra cash to do it and they do report increase in yields.
