I bought one of these co2 bags that are supposed to hang over my plant and last for around 6 months. if I had a single 3ft by 3ft bush under 2x600 hps in a 4 ft by 6ft by 8 ft room covered in mylar. and hang it a foot over it is this going to make much of a difference is it worth its money and does it change the yield or quality or both and how much? thanks for any info.
