I tried to start a new thread for this, but for some reason it will let me reply to my post but I can't start a new post. What gives?

Anyway, I am thinking of using a DIY carbon filter. Like the one here:

My question is this...
I will be using it for the growbox and during drying/curing. How often do I need to change out the activated carbon? Should I just change it when I switch from the grow to the cure? Or do I need to change it a few times throughout the grow? Thanks.
OneDayJD Reviewed by OneDayJD on . MAJOR n00b - question about smell I am thinking about doing my first grow in January. Therefore, I want to have all of my research done ahead of time. I am going to do a grow box in a closet probably with the Rubbermaid bin setup. My question is about smell. Obviously I need to keep this discreet and don't want my room and/or house to smell like pot the whole time I am growing. My question is when does it start smelling? Does it smell as soon as the plants start to grow? Or does it not start smelling until they are flowering? Rating: 5
