Ho all, I'm waiting on a carbon filter to arrive, I would love me to know why I shouldn't run the hose back into the tent for more air movement. Am I recycling dead air?
I'd have thought so yeah. Unless you had plenty of fresh air coming in through another intake too. Plus that air getting pumped back in will be the warm humid air so you might get issues with that too. No expert though, just my thoughts.
As you are recycling dead air so to speak... which has a temperature & how do you think this going to effect you grow conditions ? Yes what ever you have chosen for lighting may give off some heat ya gonna pump this through ya tent 24/7 not so cool.
But I'm assuming a grow tent & that plants need to breath - day time/lights on, Co2 in & night time/lights off Co2 out that is plant breathing through a natural cycle... should not be not to hard to understand after some basic science.
At some point you need FRESH input.
Other wise on a far out note - a closed loop system aka dehumidifier / AC / Co2 - Headache !
