I just have a simple question that I thought about after installing my carbon filter and noticing the smell it gave off. I was wondering if circulating the activated carbon exhaust back out into the room would give the plants CO2. (i.e. does the activated carbon and air getting blown out create any kind of CO2?) Just a dumb question I thought of because as soon as I installed carbon filter, I swear my plants flowering began exploding. Could just be coincidence as they are in that stage of flowering anyway. Just seems like they have made more progress in a shorter amount of time on this grow. If anyone has any ideas I would appreciate it.
