Co2 should be the last thing to add to a grow. And only when everything else is dialed in, the grower is experienced enough to have excellent harvests with healthy plants start to finish, and has nothing else to improve upon. Co2 in itself is not going to work magic. Better/more lighting than that 150 watt light would have been a better use of the money spent and would have directly impacted yield and quality. But for some reason many new growers jump straight to Co2 without having ever finished a grow.
But gotta give the OP credit for at least getting some real equipment instead of hanging one of those completely worthless Co2 bags in the tent.
