Surely these Co2 bags are useless in a well set up room.
Let's take a look at this for a moment. U are supposed to sit the bags above the plants as the co2 falls downwards onto them. However the way that the air in your room circulates would prevent the co2 from doing its job as the out take fan would the co2 away before it touches the plants. Also the ocilating fan would mess things up too.
Would a better idea not be to place the bag at the outside the room next to the intake fan? Or does it need heat to activate the bag? Oooorrrr...are they just pointless?
